Spain has finally revealed its third quantum supercomputer, a machine that is capable of developing far more complicated algorithms than conventional computers can. The supercomputer, located at the Barcelona Supercomputing Centre, or BSC, was designed and built by Barcelona-based company Qilimanjaro Quantum Tech and funded by the European Commission and Spain’s Secretariat of State for Digitalisation and Artificial Intelligence, representing a total investment of €9.8 million. The computer was revealed on Thursday, May 28 at the BSC headquarters.

Conventional computers vs. supercomputers: What is the difference?

What differentiates a supercomputer from a conventional computer is that the latter works with bits, which is short for “binary digits” and is the most basic unit of information in computer science. These bits can only represent the values 0 or 1. Supercomputers, on the other hand, use qubits, which can represent both states at once. This means that supercomputers can easily take on problems that a conventional computer can barely solve.

The newest addition to the MareNostrum 5 supercomputer system: 314 million billion calculations per second

The BSC’s third supercomputer was built to speed up research and the development of artificial intelligence. Unlike the two previous supercomputers built at the centre, the third one is analogue, while the others are digital. The machine has been made to complement the systems that are already in place.

It will be integrated into the MareNostrum 5 system, a large supercomputer already in place at the centre that is capable of performing up to 314 quadrillion calculations per second, combining classical supercomputing, quantum computing, and artificial intelligence.

This incredible machine is a main driver of European research into artificial intelligence, climate modelling, and medicine. It is housed at the chapel of Torre Girona, which was also home to the first four versions of the MareNostrum supercomputer between 2005 and 2023.

Since their launch in February 2025, the first two supercomputers have already clocked up to 4,200 computing hours and have participated in 53 research projects.

How can supercomputers impact daily life?

These machines are capable of furthering research into various sectors, and will therefore have a direct impact on science and advancement in many areas.

To begin with, these computers are capable of simulating complex human organs, leading to faster diagnoses of diseases and tailor-made, individualised medical treatments.

The supercomputers can also generate highly localised and precise meteorological data, allowing for earlier predictions for extreme weather, including storms and droughts.

They can also help with modelling major cities like Barcelona and Madrid, helping officials to plan public infrastructure and optimise traffic flow.

Supercomputers will be integral in the furthering of artificial intelligence technology, which has already taken the world by storm and is a major part of the daily life of many citizens.

They can also simulate renewable energy models, reducing carbon footprints and lowering energy costs, and much more.

Furthering European technological sovereignty and making major scientific advancements

To date, the programme promoting the new quantum computer, the European High Performance Computing Joint Undertaking, has acquired six quantum computers distributed across different European countries, including Poland, the Czech Republic and Germany.

The launch of this new supercomputer represents a significant step forward for not only Spanish computer science, but European technology as a whole. This incredible machine, capable of solving major problems in science today, including medicinal science and climate science, will also help European countries to achieve technological sovereignty and reduce reliance on infrastructure from other countries.

A few years ago, the idea of Norway joining discussions around French nuclear deterrence would probably have sounded unlikely to many people in Europe.

Now it is happening openly. And the reason is simple.

Europe’s sense of security has changed dramatically since Russia invaded Ukraine.

On Wednesday, May 27, Norwegian Prime Minister Jonas Gahr Støre confirmed in Paris that Norway will join France’s growing discussions with European countries about nuclear deterrence and defence cooperation.

Standing beside French President Emmanuel Macron, Støre said Norway would participate alongside several other European countries already involved in talks about how French nuclear capabilities could contribute to European security.

The announcement may sound highly technical at first glance, but politically it says a lot about the atmosphere currently spreading across Europe.

Countries that once felt relatively comfortable relying almost entirely on NATO and American military protection are now starting to think much more seriously about what Europe’s own defence structure could look like in the future.

And honestly, the fact that Norway is participating makes the situation feel even more significant. Because Norway has traditionally been one of the European countries closest to the United States when it comes to defence and security cooperation.

Why France is suddenly becoming central to Europe’s defence discussions

Since Brexit, France has become the European Union’s only nuclear power. That reality has pushed Emmanuel Macron into a much more important position inside Europe’s defence conversations over the past few years.

Back in March, Macron revealed that several countries had already agreed to begin discussions with France around possible nuclear cooperation.

Germany, Poland, Sweden, Denmark, Belgium, Greece and the Netherlands were among the countries mentioned at the time.

Now Norway has officially joined that group too.

Much of what is being discussed remains confidential, but officials have already indicated the talks could involve joint military exercises, intelligence sharing and possible cooperation involving French nuclear capable Rafale fighter jets.

French officials reportedly described the broader concept as a form of ‘forward nuclear deterrence’.

At the moment, nobody is suggesting France is preparing to place nuclear weapons across Europe tomorrow. Norway itself stressed very clearly that no nuclear weapons would be deployed on Norwegian soil during peacetime.

Still, the symbolism matters enormously. Because Europe’s political mood around defence has changed very noticeably since 2022.

Conversations that once felt uncomfortable or politically sensitive are now happening far more openly. And a lot of that anxiety comes directly from geography.

Norway shares a border with Russia in the Arctic region and sits close to some of Russia’s most important military and nuclear infrastructure.

Speaking in Paris, Støre pointed out that Russia’s largest nuclear arsenal is located in the High North only a relatively short distance from Norwegian territory.

Why many European countries are rethinking defence strategy

Officially, NATO remains at the centre of European security. That has not changed.

Norwegian leaders themselves repeated very clearly that the alliance remains the foundation of Norway’s defence policy.

But at the same time, many European governments are becoming increasingly nervous about depending too heavily on a single system during a period of growing geopolitical uncertainty.

Especially with questions continuing around future American foreign policy.

Donald Trump’s return to US politics has added another layer of concern for some European governments, particularly those wondering how stable long term American military commitments may remain in the future.

That uncertainty has encouraged several countries to strengthen defence ties inside Europe itself alongside NATO structures rather than relying exclusively on Washington.

Before 2022, discussions about European “strategic autonomy” in defence often sounded abstract and distant.

Now they feel much more real. Military budgets are rising across Europe. Countries are modernising armed forces at speed and defence cooperation between European governments has intensified significantly over the last few years.

Nordic countries especially have moved much closer together on security matters since the start of the war.

Finland joined NATO, Sweden followed shortly afterwards and Arctic security itself has become far more important strategically as tensions continue growing between Russia and NATO countries in northern Europe.

The new France Norway defence agreement reflects a changing Europe

Alongside the nuclear discussions, France and Norway also signed a wider defence and security agreement on Wednesday known as the Narvik agreement.

The deal includes cooperation around air defence, military planning, Arctic security and increased coordination between the armed forces of both countries.

Again, none of this appeared suddenly out of nowhere. The political atmosphere across Europe has shifted steadily over the past few years.

And honestly, many European leaders no longer seem convinced that the continent can afford to think about security the same way it did before Russia invaded Ukraine.

That does not mean Europe is preparing for war tomorrow. But it does mean governments are increasingly planning for a future where military deterrence, defence coordination and long term security risks are no longer treated as distant theoretical problems. Because for many European countries today, especially those geographically closer to Russia, the sense of vulnerability feels far more real than it did only a few years ago. And that changing feeling is starting to reshape Europe’s defence conversations very quickly.

A 37-year-old British man has died following a violent altercation in the Las Verónicas nightlife area of Playa de las Américas, in southern Tenerife. The incident occurred during the early hours of Thursday in one of the island’s busiest entertainment districts, an area known for its concentration of bars, clubs and late-night venues that attract large numbers of international visitors, particularly British tourists.

Emergency services were called to the scene after reports of a fight between two men in the area. Despite rapid intervention by paramedics, the man was pronounced dead shortly afterwards. Local police confirmed that the incident involved two British nationals and took place on the street outside nightlife venues in the area.

Arrest of 23-year-old British man

Spanish Policía Nacional arrested a 23-year-old British man shortly after the incident in connection with the death. According to information reported in Spanish media based on police sources, the two men were involved in a confrontation that escalated into a physical fight. Officers detained the suspect at the scene or in its immediate vicinity following the incident.

Authorities have not released the names of either individual. It has also not been confirmed whether the victim or suspect were residents of Tenerife or visiting tourists, although the area is a well-known holiday destination for British travellers. The suspect remains in police custody while investigations continue.

Emergency response and attempts to save life

Emergency medical personnel were deployed to Las Verónicas after receiving alerts about a serious assault. Paramedics carried out advanced resuscitation efforts at the scene, attempting to stabilise the victim. Despite these efforts, the man was confirmed dead at the location in the early hours of the morning. His death was certified shortly after emergency crews arrived.

Local emergency services also secured the area while police began their initial investigation, including gathering witness accounts from people in nearby bars and streets. Parts of the nightlife strip were temporarily cordoned off while forensic officers examined the scene.

Early reports suggest a single strike

Preliminary reporting from the media, citing police sources, indicates that the confrontation escalated rapidly and may have involved a single decisive blow during the fight. According to these early accounts, one of the men struck the other during the altercation, after which the victim collapsed. Emergency responders later found him in cardiac arrest.

The precise cause of death will be determined following a post-mortem examination. Authorities have not officially confirmed the exact medical cause at this stage. Investigators have not disclosed what led to the argument or whether alcohol, prior contact, or external factors played a role in the dispute.

Police investigation ongoing

The Spanish Policía Nacional have opened a full investigation into the circumstances surrounding the incident. Officers are working to reconstruct the timeline of events leading up to the confrontation and the fatal outcome. As part of the investigation, police are reviewing CCTV footage from surrounding nightlife venues and street cameras in the Las Verónicas area.

Statements from witnesses are also being collected, including from staff at nearby bars and clubs. The suspect remains in custody while investigators prepare reports for judicial authorities. Further legal proceedings will depend on forensic findings and the outcome of the investigation.

Las Verónicas nightlife district

Las Verónicas, located in Playa de las Américas in southern Tenerife, is one of the island’s most well-known nightlife zones. It is particularly popular with British and European holidaymakers and features a dense concentration of bars, clubs and late-night entertainment venues.

The area attracts thousands of visitors, especially during peak holiday periods. Local authorities have previously increased policing in the district due to incidents associated with nightlife activity, although serious violent cases remain relatively uncommon compared with overall visitor numbers. The incident has drawn attention due to the fatal outcome and the involvement of two British nationals in a popular tourist area.

No further official details released

At the time of reporting, authorities have not released the identity of the victim or confirmed whether he was travelling in Tenerife as a tourist. Officials have also not provided further details on the relationship between the two men, if any existed prior to the incident.

The investigation remains active, and further updates are expected once forensic analysis, witness statements and CCTV evidence have been fully reviewed by investigators.
