Quantum 9, 1787 (2025). https://doi.org/10.22331/q-2025-07-09-1787 Quantum trajectories of a Markovian open quantum system arise from the back-action of measurements performed in the environment with which the system interacts. In this work, we consider counting measurements […]
With the ability to detect and amplify extremely weak electromagnetic signals without adding additional noise, masers have many potential uses, including the production of more sensitive magnetic resonance body scanners, such as those used in […]
Excitons—bound pairs of electrons and an electron hole—are quasiparticles that can arise in solids. While so-called “bright” excitons emit light and are therefore accessible, dark excitons are optically inactive. As a result, they have a […]
Insider Brief Quandela and Mila have partnered to advance quantum machine learning by combining photonic quantum computing with artificial intelligence research. The collaboration will focus on benchmarking QML models, identifying potential quantum advantages, solving training […]
Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, internal structure, and de-excitation properties of […]
Quantum computers have the potential to revolutionize computing by solving complex problems that stump even today’s fastest machines. Scientists are exploring whether quantum computers could one day help streamline global supply chains, create ultra-secure encryption […]
Randomness is a source of power. From the coin toss that decides which team gets the ball to the random keys that secure online interactions, randomness lets us make choices that are fair and impossible […]
Insider Brief UbiQD has signed an exclusive multi-year supply agreement with First Solar to integrate its quantum dot (QD) technology into thin-film bifacial solar panels. The deal follows successful joint R&D and could scale UbiQD’s […]
Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left thinking something […]
A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur Ruhlig, a little-known physicist, first observed signs […]
