A third quantum computer lands in Barcelona to lead Europe's technological revolution The Barcelona Supercomputing Center reaffirms its commitment to leading the EU's "technological sovereignty" BarcelonaNew scientific milestone for Barcelona, which continues to take steps to consolidate itself as one of the European capitals of knowledge, research and innovation. This Thursday, the Barcelona Supercomputing Center (BSC-CNS) has officially presented its third quantum computer, the EuroQCS-Spain, which with a cost of 9.8 million euros makes the institution one of the few centers in the world that combine supercomputing and quantum technology. "It is the only one with three quantum computers connected to a classic supercomputer," claimed the director of the BSC, Mateo Valero, during the presentation of the new technology, which has been co-financed by the European Commission and the Spanish government. Currently, supercomputers like the one at the BSC, MareNostrum 5, do not have enough capacity to tackle challenges of "great computational complexity", as they "would take too long" to process the information requested, explained Valero. This is where quantum computers like the one inaugurated this Thursday come into play, which in the future must be capable of solving problems that are unassailable for classic supercomputing. In this aspiration, Catalonia wants to establish itself as a global reference hub. With this Thursday's incorporation, the BSC now has two digital quantum computers and one analog. What differentiates them is how they process information: the digital system is more suitable for solving mathematical and cryptographic problems and search algorithms, and the analog allows tackling physical phenomena, optimizing the resolution of logistical problems, and training AI models. Valero explained that all the algorithms they are currently developing have some part of artificial intelligence. "For example, we are undertaking a major challenge which is the simulation of the future European combat aircraft. Without artificial
