Nonreciprocal quantum batteries exhibit remarkable capacities and efficiency

In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which ...

Mapping noise to improve quantum measurements

One of the biggest challenges in quantum technology and quantum sensing is "noise"–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information.

Quantum computers are like kaleidoscopes: Why unusual metaphors help illustrate science and technology

Quantum computing is like Forrest Gump's box of chocolates: You never know what you're gonna get. Quantum phenomena—the behavior of matter and energy at the atomic and subatomic levels—are not definite, one thing or another. ...

Pseudomagic quantum states: A path to quantum supremacy

A new study in Physical Review Letters (PRL) introduces the concept of pseudomagic quantum states, which appear to have high stabilizerness (or complexity) and can move us closer to achieving quantum supremacy.
