Physicists show knotted cosmic strings may have dominated the early universe before collapsing to create matter—a theory ...

Qubits differ from classical bits, which are coded as only 0 or 1. A qubit can be a combination of both 0 and 1 simultaneously. One way to think of it is as a coin spinning between a 0 and a 1 axis.

Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect quantum entanglement without destroying it.

The proof, known to be so hard that a mathematician once offered 10 martinis to whoever could figure it out, uses number ...

The uncertainty inherent to quantum mechanics has long left physicists wondering whether the observations we make on the ...

Combining a quantum-inspired algorithm and quantum information processing technologies could enable researchers to measure ...

Modern multiverse fiction incorporates real physics equations and string theory principles rather than relying on pure ...

If these knots had a slight bias toward matter over antimatter, their unraveling could help explain the matter-antimatter ...

Abstract: The unique features of entanglement and non-locality in quantum systems, where there are pairs of bipartite states perfectly distinguishable by general entangled measurements yet ...

Abstract: Differential privacy provides a robust framework for protecting sensitive data, while maintaining its utility for computation. In essence, a differentially private algorithm takes as input ...

Quantum physics can seem like a maze of strange ideas and confusing math, but the right book can make it all click. Whether you’re just starting out or you’ve been curious for years, there are plenty ...
