The U.S. National Science Foundation (NSF) is investing $16 million in four teams to design high-tech infrastructure for the NSF National Quantum Virtual Laboratory (NQVL). Each team will receive a $4 million grant over two […]
The Chicago Quantum Exchange (CQE) has announced that Belden, a provider of network infrastructure and connection solutions, and Photon Queue, a quantum hardware startup, have joined as corporate partners. This move highlights the growing collaboration […]
The Business Software Alliance (BSA), a global trade association of the enterprise software industry, has released its inaugural policy agenda on quantum computing. The agenda presents a strategic roadmap designed to help governments accelerate the […]
BTQ Technologies Corp. (BTQ) has announced that its Quantum Secure Stablecoin Network (QSSN) has been highlighted by the U.S. Post-Quantum Financial Infrastructure Framework (PQFIF) as a model for quantum-secure tokenized deposits. Concurrently, the Quantum Industrial […]
A new study addresses a foundational problem in the theory of driven quantum matter by extending the Středa formula to non-equilibrium regimes. It demonstrates that a superficially trivial “sum of zeros” encodes a universal, quantized […]
Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens new possibilities for exploring fundamental […]
A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal. The paper is published in the journal Physical Review X. […]
Quantum 9, 1857 (2025). https://doi.org/10.22331/q-2025-09-11-1857 Many promising quantum applications depend on the efficient quantum simulation of an exponentially large sparse Hamiltonian, a task known as sparse Hamiltonian simulation, which is fundamentally important in quantum computation. […]
Quantum 9, 1856 (2025). https://doi.org/10.22331/q-2025-09-11-1856 We present BAE, a problem-tailored and noise-aware Bayesian algorithm for quantum amplitude estimation. In a fault tolerant scenario, BAE is capable of saturating the Heisenberg limit; if device noise is […]
Quantum 9, 1855 (2025). https://doi.org/10.22331/q-2025-09-11-1855 Highly correlated biphoton states are powerful resources in quantum optics, both for fundamental tests of the theory and practical applications. In particular, high-dimensional spatial correlation has been used in several […]
