Scientists achieve the first direct measurement of the quantum metric tensor in black phosphorus, advancing understanding of quantum states in solid materials. (Nanowerk News) Quantum distance refers ...

Quantum metric spaces extend the classical notion of metric spaces into the noncommutative realm by utilising operator algebras and associated seminorms to capture geometric structure in settings ...

A hidden quantum geometry that distorts electron paths has finally been observed in real materials. This “quantum metric,” once thought purely theoretical, may revolutionize electronics, ...

Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have stubbornly resisted every attempt to bring them under one roof. A new geodesic-based ...

Quantum distance refers to a measure of quantum mechanical similarity between two quantum states. A quantum distance of one means that the two quantum states are the same, whereas a quantum distance ...
