Insider Brief: ETRI, in collaboration with KAIST and the University of Trento, developed an 8-photon silicon photonic integrated quantum circuit, achieving 6-qubit entanglement, with future plans for scaling up to 32 qubits. The silicon photonics […]
Insider Brief: IQM Quantum Computers and Volkswagen demonstrated the CS-AFQMC method, which integrates quantum and classical resources to improve simulations of strongly correlated systems, achieving chemical accuracy with fewer qubits in applications like lithium-ion battery […]
A new route to materials with complex disordered magnetic properties at the quantum level has been produced by scientists for the first time. The material, based on a framework of ruthenium, fulfills the requirements of […]
Insider Brief Nirvanic Consciousness Technologies Inc., a Vancouver-based quantum-AI startup, has emerged from stealth to explore the computational basis of consciousness in creating safer, human-aligned artificial intelligence systems. The company aims to use quantum computing […]
Water, a molecule essential for life, has unusual properties—known as anomalies—that define its behavior. However, there are still many enigmas about the molecular mechanisms that would explain the anomalies that make the water molecule unique. […]
South Korea’s SDT Inc. has partnered with MIMOS Technology Solutions, a subsidiary of Malaysia’s national R&D agency, MIMOS, to open Malaysia’s first Quantum Computing Centre. With SDT’s experience in quantum communication and ultra-precision electronics, the […]
Germany’s QSolid project is led by the Jülich Research Center and includes 25 German institutions. It is funded by the Federal Ministry of Education and Research (BMBF), which has provided 90% of the funding to […]
A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when measured. They published a description of their experiment in the journal Physical Review Letters and state […]
Insider Brief: Atlantic Quantum, in collaboration with MIT’s Kevin P. O’Brien, received a $1.8 million Phase II STTR grant from AFWERX to develop scalable superconducting quantum computers for the Department of the Air Force (DAF), […]
Quantum 8, 1525 (2024). https://doi.org/10.22331/q-2024-11-14-1525 The extension of the Rayleigh-Ritz variational principle to ensemble states $rho_{mathbf{w}}equivsum_k w_k |Psi_krangle langlePsi_k|$ with fixed weights $w_k$ lies ultimately at the heart of several recent methodological developments for targeting […]
