Back in 2019, Google made waves by claiming it had achieved what has been called “quantum supremacy”—the ability of a quantum computer to perform operations that would take a wildly impractical amount ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Quantum phase transitions and topological phases constitute a vibrant domain within condensed matter physics. Unlike classical transitions driven by thermal fluctuations, quantum phase transitions ...

This image depicts the ultracold atomic quantum simulator. The red and blue balls represent the fermionic atoms with up and down spins, respectively, arranged in a staggered pattern in 3D space, ...

After decades of looking, researchers have seen a string of atoms go through a 1D phase change so elusive that it could only happen inside a quantum simulator. “One motivation [for our experiment] is ...

Quantum phase transitions describe abrupt changes in the ground state of a quantum system at absolute zero when a control parameter is varied. They are distinguished from classical phase transitions ...

Quantum annealer D-Wave’s Advantage2 was one of the processors used to simulate quantum magnetic phase transitions. (Courtesy: D-Wave Systems) D-Wave Systems has used quantum annealing to do ...
