Duality ellipse The amount of coherence is linked to the amount of waveness and particleness of a quantum system through an duality ellipse relation. The coherence, modulated by the object shape, can ...

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

Advancements in quantum imaging are transforming scientific research, offering unprecedented resolution and sensitivity for ...

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and ...

For quantum computers to change the game of computation, scientists need to show that the machines’ calculations are correct. Now, there’s hope. Google’s Willow quantum chip has achieved verifiable ...

For two decades, a deceptively simple question has split condensed‑matter physicists: do the electrons in gold quietly align their spins, or is the metal as magnetically featureless as textbooks claim ...

Scientists in the U.K. have successfully connected two separate quantum processors, paving the way for a quantum internet and, potentially, quantum supercomputers. Increasing the number of quantum ...

Quantum superposition is a phenomenon in which a tiny particle can be in two states at the same time — but only if it is not being directly observed. When you purchase through links on our site, we ...

Quantum computers are still in their infancy. Presently limited to 100 or so error-prone qubits, the quantum equivalents to classical bits, they are far from supreme calculating machines that are ...
