What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics. Click to […]
Prime Minister’s Announcement As reported by The Quantum Insider yesterday, Prime Minister Justin Trudeau announced a $40-million contribution to a Toronto quantum startup Xanadu Quantum Technologies as they work towards building the world’s first fault-free […]
The second law of thermodynamics is often considered to be one of only a few physical laws that is absolutely and unquestionably true. The law states that the amount of ‘entropy’—a physical property—of any closed […]
When it comes to creating ever more intriguing quantum systems, a constant need is finding new ways to observe them in a wide range of physical scenarios. JILA Fellow Cindy Regal and JILA and NIST […]
When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. […]
Physical systems evolve at a particular speed, which depends on various factors including the system’s so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods for […]
The cosmos seems to have a preference for things that are round. Planets and stars tend to be spheres because gravity pulls clouds of gas and dust toward the center of mass. The same holds […]
Quantum 7, 904 (2023). https://doi.org/10.22331/q-2023-01-24-904 We consider a system of multiple qubits without any quantum control. We show that one can mediate entanglement between different subsystems in a controlled way by adding a (locally) controlled […]
Alain Aspect is a French physicist whose ground-breaking work quantum entanglement later led to the 2022 Nobel Prize in Physics, awarded jointly with John Clauser and Anton Zeilinger. Dr. Aspect, in addition to being a […]
