The Observer Effect and Quantum MechanicsIn Episode 5, we looked at the horizon of the "multiverse" depicted by eternal ...

A quantum simulator has given physicists a new look at one of the strangest ...

An international team led by Innsbruck quantum physicist Peter Zoller, together with the US company QuEra Computing, has directly observed a gauge field theory similar to models from particle physics ...

Strike a bell, and it rings with a pitch and a fading that tell you about the bell: its size, its shape, the metal it is made of. Black holes ring too. When two merge, the newborn black hole shivers ...

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

Duke's 13-ion experiment completes a trio of string-breaking results across three quantum platforms. Here is what it proves ...

Researchers used 13 trapped ions to simulate string breaking, showing how quantum hardware could help scientists explore ...

In light of the recent criticisms of string theory, preeminent physicist Juan Maldacena sheds light on the promise of string theory and how it fits into our current understanding of the universe. In ...

String theory seeks to describe fundamental interactions by modelling particles as one-dimensional strings. In efforts to unify quantum mechanics and general relativity, it introduces additional ...

Theoretical physicists routinely introduce fictitious particles and fields in their calculations, in view of completing a theory or simply to make it more elegant. A striking example concerns the ...

String field theory is a second-quantised framework that recasts the perturbative dynamics of strings in terms of field-theoretic variables on the space of string configurations. By organising ...
