Quantum 9, 1807 (2025). https://doi.org/10.22331/q-2025-07-22-1807 Certifying quantum properties from the probability distributions they induce is an important task for several purposes. While this framework has been largely explored and used for quantum states, its extrapolation […]
Quantum 9, 1806 (2025). https://doi.org/10.22331/q-2025-07-22-1806 Quantum state estimation is a fundamental task in quantum information theory, where one estimates real parameters continuously embedded in a family of quantum states. In the theory of quantum state […]
Quantum 9, 1805 (2025). https://doi.org/10.22331/q-2025-07-22-1805 Block encoding severs as an important data input model in quantum algorithms, enabling quantum computers to simulate non-unitary operators effectively. In this paper, we propose an efficient block-encoding protocol for […]
Quantum 9, 1804 (2025). https://doi.org/10.22331/q-2025-07-22-1804 Autonomous quantum memories are a way to passively protect quantum information using engineered dissipation that creates an “always-on” decoder. We analyze Markovian autonomous decoders that can be implemented with a […]
Quantum 9, 1803 (2025). https://doi.org/10.22331/q-2025-07-22-1803 We investigate the challenge of classical simulation of unitary quantum dynamics with variational Monte Carlo approaches, addressing the instabilities and high computational demands of existing methods. By systematically analyzing the […]
Quantum 9, 1802 (2025). https://doi.org/10.22331/q-2025-07-22-1802 Non-Abelian gauge theories underlie our understanding of fundamental forces of modern physics. Simulating them on quantum hardware is an outstanding challenge in the rapidly evolving field of quantum simulation. A […]
Riverlane, a quantum error correction (QEC) company, has announced the integration of its second-generation QEC technology, Deltaflow 2, at a commercial data center operated by CentreSquare, where it is co-located with an Oxford Quantum Circuits […]
Multi-wavelength light sources are required for optical transceivers to increase data. However, scaling the laser array size increases thermal crosstalk, which may affect laser efficiency and reliability. Click to rate this post! [Total: 0 Average: […]
Quantum teleportation is a fascinating process that involves transferring a particle’s quantum state to another distant location, without moving or detecting the particle itself. This process could be central to the realization of a so-called […]
There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin gravitational wave detectors (one in Hanford, Washington, and the other in Livingston, Louisiana), laser beams bounce back and […]
