A researcher at Kyushu University and his collaborators have shown that continuous parameters in quantum gravity may not be freely adjustable "dials" from outside the theory, but rather arise from ...

Quantum differential operators, encompassing Schrödinger, Dirac and more general elliptic operators, serve as fundamental constructs in the mathematical description of quantum phenomena. Spectral ...

In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical theories, often unveiling hidden symmetries. Some recent studies have been aimed ...

Variational quantum algorithms. In methods like the Variational Quantum Eigensolver, where expectation values of observables are computed repeatedly, Pauli propagation offers a fast classical proxy ...

There is a law that quantum computing has lived under since its earliest days, something between an engineering inconvenience and a fundamental insult: the more you try to harness quantum mechanics, ...
