Theoretical physicists routinely introduce fictitious particles and fields in their calculations, in view of completing a theory or simply to make it more elegant. A striking example concerns the magnetic monopole imagined by Dirac in 1931: a […]
Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There […]
Every time you reach for your coffee mug, a neuroscientific mystery takes shape. Moments before you voluntarily extend your arm, thousands of neurons in the motor regions of your brain erupt in a pattern of […]
PRESS RELEASE — Sandbox AQ, an enterprise SaaS company delivering solutions that leverage quantum tech and AI, officially launched today and announced its investors, board chair, partners, advisors and initial customers. AQ stands for AI […]
At the height of the pandemic in 2019, traders used a derivative — named a call option — to boost a relatively unappreciated and borderline tanking GameStop (GME) stock into one of the most highly […]

Quantum 6, 672 (2022). https://doi.org/10.22331/q-2022-03-22-672 Thermal machines exploit interactions with multiple heat baths to perform useful tasks, such as work production and refrigeration. In the quantum regime, tasks with no classical counterpart become possible. Here, […]
Quantum computing continues to advance at a rapid pace, but one challenge that holds the field back is mitigating the noise that plagues quantum machines. This leads to much higher error rates compared to classical […]
Quantum 6, 671 (2022). https://doi.org/10.22331/q-2022-03-22-671 How can a multipartite single-photon path-entangled state be certified efficiently by means of local measurements? We address this question by constructing an entanglement witness based on local photon detections preceded […]
