Quantum phase transitions represent fundamental changes between distinct quantum states of matter, driven not by thermal fluctuations but by quantum fluctuations at zero temperature. These transitions ...

Quantum Markov chains (QMCs) represent a natural quantum extension of classical Markov processes, encapsulating memoryless dynamics within quantum systems. They offer a powerful framework to model non ...

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 ...

Researchers have achieved a remarkable result: capturing and studying phase changes in quantum hardware, which hold hold promise for next-generation technologies like quantum computing and ...

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, ...

A stable "exceptional fermionic superfluid," a new quantum phase that intrinsically hosts singularities known as exceptional ...

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 ...

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 ...

The secret to more plentiful, unconventional superconducting materials could lie in an “exotic physics” trigger called the Griffiths singularity. After 55 years, physicists are finally beginning to ...

Physicists with the U.S. Department of Energy have discovered a new phase of matter—and, with apologies to George R. R. Martin, it's something of "a song of ice and fire." The new phase comes in the ...

Experiments on Google's 67-qubit Sycamore processor showed operations entering a new "weak noise phase" in which calculations were complex enough to outperform supercomputers, based on benchmark ...
