Quandela, the European leader in photonic quantum computing, announces a major breakthrough for the sector in a scientific paper describing a reduction by a factor of 100,000 in the number of components required for fault-tolerant calculations. Quandela’s hybrid approach, based on a technology that generates photonic qubits with unprecedented efficiency from artificial atoms (semiconductor quantum emitters), should enable the company to accelerate the scaling-up of its quantum computers.

Physicists have built a new type of digital-analogue quantum simulator in Google’s laboratory, which can be used to study physical processes with unprecedented precision and flexibility. Two physicists from PSI’s Center for Scientific Computing, Theory and Data, played a key role in this achievement.

Quantum spin liquids are fascinating states of matter where magnetic spins stay disordered, defying the usual rules of magnetism. Professor Yasuyuki Ishii and his team have made an exciting discovery about one such material, β’-EtMe₃Sb[Pd(dmit)₂]₂. Instead of acting like a 2D system as expected, it behaves like a 1D system. This breakthrough changes how we understand these mysterious materials, offering new insights into magnetism and opening doors to advances in quantum materials and technology.

The results now published pinpoint the spiral magnetic structure of these materials, finally establishing the common origin of its promising magnetic and electric properties up to room temperatures. The experiments were fully conducted at the ILL, using five instruments out of a state-of-the-art suite of over 40, and taking advantage of advanced sample environment technologies.

The future of tin-based qubits is brighter thanks to breakthrough work by Stanford University researchers supported through a quantum research center led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory.

To promote the sustainability of electromobility and enhance resource efficiency, upcycling of lithium-ion batteries is gaining increasing importance. Efforts are focused on slowing down material cycles by repurposing used batteries from electric vehicles for new applications instead of transferring them directly to recycling processes. Despite its real significant potential to conserve resources, upcycling has yet caught on due to technical and economic challenges. However, a team of researchers has developed a practical method that combines a high-speed measurement method and artificial intelligence (AI) to overcome these barriers.
