Matrix phase-space representations for quantum symmetries
Peter D. Drummond, Alexander S. Dellios, Margaret D. Reid
We introduce a general phase-space representation that includes global quantum symmetries in the basis expansion. This method, called matrix phase-space, projects the basis onto a…
Gaussian boson sampling: Benchmarking quantum advantage
Ned Goodman, Alexander S. Dellios, Margaret D. Reid +1
Quantum computers solve intractable problems which classically require an exponentially long time to compute. With the development of large-scale experiments that claim quantum adv…
Matrix phase-space representations for gaussian boson sampling
Peter D. Drummond, Alexander S. Dellios, Margaret D. Reid
We introduce coherent matrix phase-space distributions. These use conservation laws and symmetries to improve the accuracy and speed of quantum phase-space representations. As an e…
Validation tests of Gaussian boson samplers with photon-number resolving detectors
Alexander S. Dellios, Margaret D. Reid, Peter D. Drummond
An important challenge with the current generation of noisy, large-scale quantum computers is the question of validation. Does the hardware generate correct answers? If not, what a…
A macroscopic quantum three-box paradox: finding consistency with weak macroscopic realism
C. Hatharasinghe, M. Thenabadu, P. D. Drummond +1
The quantum three-box paradox considers a ball prepared in a superposition of being in one of three Boxes. Bob makes measurements by opening either Box 1 or Box 2. After performing…
Quantifying the mesoscopic nature of the Einstein-Podolsky-Rosen nonlocality
M. D. Reid, Q. Y. He
Evidence for Bell's nonlocality is so far mainly restricted to microscopic systems, where the elements of reality that are negated predetermine results of measurements to within on…
