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 […]
A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). It is a system capable of controlling eight photons using a photonic integrated-circuit chip. With this system, […]
Insider Brief: Researchers developed a quantum-inspired genetic algorithm that merges natural selection principles with quantum mechanics to optimize photonic layer designs, specifically for transparent radiative cooling systems. The QGA allows for faster and more efficient […]
For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists at the Max-Planck-Institute for the Science of Light (MPL) have now demonstrated a […]
Quantum 8, 1524 (2024). https://doi.org/10.22331/q-2024-11-14-1524 Observational entropy captures both the intrinsic uncertainty of a thermodynamic state and the lack of knowledge due to coarse-graining. We demonstrate two interpretations of observational entropy, one as the statistical […]
