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

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

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 ...

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

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

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 ...

Physicists have put a decades-old idea about why the strange rules of quantum mechanics disappear in our everyday world to ...

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 ...
