Our intuition tells us that it should be impossible to see whether two identical objects have been swapped back and forth, and for all particles observed to date, that has been the case. Until now. […]

The excitonic insulator is an electronically driven phase of matter that can occur in solids. Scientists are searching for ways to detect and stabilize this exotic order in candidate quantum materials because it could pave […]
The silicon microchips of future quantum computers will be packed with millions, if not billions of qubits—the basic units of quantum information—to solve the greatest problems facing humanity. And with millions of qubits needing millions […]
The development of quantum computing means that the use of classic cryptography for secure communications is in danger of becoming obsolete. Quantum cryptography, on the other hand, uses the laws of quantum mechanics to ensure […]
A group of researchers led by Andreas Wallraff, Professor of Solid State Physics at ETH Zurich, has performed a loophole-free Bell test to disprove the concept of “local causality” formulated by Albert Einstein in response […]
An international collaboration of researchers, including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has succeeded in a proof-of-principle experiment to verify strong-field quantum electrodynamics with exotic atoms, by performing […]
A surprise observation of negative mass in exciton–polaritons has added yet another dimension of weirdness to these strange light-matter hybrid particles. Click to rate this post! [Total: 0 Average: 0]You have already voted for this […]
In a development that could make quantum computers less prone to errors, a team of physicists from Quantinuum, California Institute of Technology and Harvard University has created a signature of non-Abelian anyons (nonabelions) in a […]
The way light moves around inside an optical microcavity provides an exciting opportunity to explore the connection between classical and quantum physics. This field of research is known as quantum chaos, and it has the […]
It is often desirable to restrict flows—whether of sound, electricity, or heat—to one direction, but naturally occurring systems almost never allow this. However, unidirectional flow can indeed be engineered under certain conditions, and the resulting […]
