In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image […]
Quantum 8, 1245 (2024). https://doi.org/10.22331/q-2024-02-08-1245 We present a generalized framework to adapt universal quantum state approximators, enabling them to satisfy rigorous normalization and autoregressive properties. We also introduce filters as analogues to convolutional layers in […]
Quantum 8, 1244 (2024). https://doi.org/10.22331/q-2024-02-08-1244 We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are insufficient […]
Insider Brief Nord Quantique demonstrated quantum error correction to improve qubit coherence lifetime at the individual qubit level. The research shows an increase of 14% in the lifetime of a single qubit without using the […]
Testing and benchmarking are crucial steps in adopting and commercialising technologies. In the rapidly emerging world of quantum computing, where complexity and novelty present formidable challenges, the role of rigorous testing and benchmarking becomes not […]
Unrelated Announcement (Feb. 7): Huge congratulations to longtime friend-of-the-blog John Preskill for winning the 2024 John Stewart Bell Prize for research on fundamental issues in quantum mechanics! On the heels of my post on the […]
Guest Post by Karina Robinson Artificial Intelligence (AI) suffers from two massive blocks: colossal, costly energy use and a transparency deficit. The technology can be technically feasible but is still too expensive for most organisations […]
An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement of […]
Imagine that a grid of hexagons, honeycomb-like, stretches before you. Some hexagons are empty; others are filled by a 6-foot tall column of solid concrete. The result is a maze of sorts. For over half […]
Reliable quantum gates are the fundamental component of quantum information processing. However, achieving high-dimensional unitary transformations in a scalable and compact manner with ultrahigh fidelities remains a great challenge. Click to rate this post! [Total: […]
