A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use of spin defects in hexagonal boron nitride (hBN) as powerful, room-temperature sensors capable of detecting […]
Quantum 9, 1758 (2025). https://doi.org/10.22331/q-2025-05-28-1758 We propose a novel Reinforcement Learning (RL) method for optimizing quantum circuits using graph-theoretic simplification rules of ZX-diagrams. The agent, trained using the Proximal Policy Optimization (PPO) algorithm, employs Graph […]
Quantum 9, 1757 (2025). https://doi.org/10.22331/q-2025-05-28-1757 In some physical implementations of quantum computers, 2-qubit operations can be applied only on certain pairs of qubits. Compilation of a quantum circuit into one compliant to such qubit connectivity […]
Quantum 9, 1756 (2025). https://doi.org/10.22331/q-2025-05-28-1756 We study a coarse-graining procedure for quantum cellular automata on hypercubic lattices that consists in grouping neighboring cells into tiles and selecting a subspace within each tile. This is done […]
Quantum 9, 1755 (2025). https://doi.org/10.22331/q-2025-05-28-1755 The quantum state preparation of probability distributions is an important subroutine for many quantum algorithms. When embedding $D$-dimensional multivariate probability distributions by discretizing each dimension into $2^n$ points, we need […]
Inside Manu Prakash are two scientists. A bioengineer at Stanford University, he spends half his time studying urgent health issues with global impact and the rest pursuing questions “of no use to anyone,” he said. […]
A study in Nature describes both the mechanism and the material conditions necessary for superfluorescence at room temperature. The work could serve as a blueprint for designing materials that allow exotic quantum states—such as superconductivity, […]
Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers—examples include photons, which mediate electromagnetic interactions, […]
Bristol Quantum Information Technologies Workshop 2026 Submitted by BQIT on Wed, 28/05/2025 – 14:08. Dates: Monday, April 27, 2026 to Wednesday, April 29, 2026 Submission deadline: Friday, March 13, 2026 Registration deadline: Thursday, April 23, […]
A team of researchers at AI Google Quantum AI, led by Craig Gidney, has outlined advances in quantum computer algorithms and error correction methods that could allow such computers to crack Rivest–Shamir–Adleman (RSA) encryption keys […]
