Toy Models of a Nonassociative Quantum Mechanics

open access: yesAdvances in High Energy Physics, 2007
Toy models of a nonassociative quantum mechanics are presented. The Heisenberg equation of motion is modified using a nonassociative commutator. Possible physical applications of a nonassociative quantum mechanics are considered.

Wigner Distribution Sets Universal Lower Bound for Quantum Advantage in Gaussian Boson Sampling [PDF]

open access: yesEntropy
The computational complexity, or quantum advantage, of Gaussian boson sampling is ascribed to squeezing of the Wigner quasiprobability distribution. This approach reveals the physical origin of the quantum complexity resource.

High-threshold and low-overhead fault-tolerant quantum memory [PDF]

open access: yesNature, 2023
The accumulation of physical errors1–3 prevents the execution of large-scale algorithms in current quantum computers. Quantum error correction4 promises a solution by encoding k logical qubits onto a larger number n of physical qubits, such that the ...

Berry curvature and quantum metric in N -band systems: An eigenprojector approach [PDF]

open access: yesPhysical review B, 2021
The eigenvalues of a parameter-dependent Hamiltonian matrix form a band structure in parameter space. In such N -band systems, the quantum geometric tensor (QGT), consisting of the Berry curvature and quantum metric tensors, is usually computed from ...

Toward simulating quantum field theories with controlled phonon-ion dynamics: A hybrid analog-digital approach [PDF]

open access: yesPhysical Review Research, 2021
Quantum field theories are the cornerstones of modern physics, providing relativistic and quantum mechanical descriptions of physical systems at the most fundamental level.
