Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has ...

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

This article investigates Quantum Fisher Information (QFI) as a diagnostic tool for analyzing parameter sensitivity and ...

New advances in entanglement witnesses allow researchers to verify genuine multipartite entanglement even in noisy, high‑dimensional and computationally relevant quantum states Quantum entanglement ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Computer science, at its most fundamental, is all about inputs and outputs. Consider the simple case of multiplying two numbers on a pocket calculator. You punch in some inputs — the specific numbers ...

Investors recently learned that quantum computers could one day be used to steal Bitcoin. That isn't going to happen in the near future, if ever. But, during the panic of the recent sell off, some ...
