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…
Simulating Gaussian boson sampling quantum computers
Alexander S. Dellios, Margaret D. Reid, Peter D. Drummond
A growing cohort of experimental linear photonic networks implementing Gaussian boson sampling (GBS) have now claimed quantum advantage. However, many open questions remain on how…
The Quantum and Stochastic Toolbox: xSPDE4.2
Peter D. Drummond, Run Yan Teh, Manushan Thenabadu +5
This is the fourth major release of the xSPDE toolbox, which solves stochastic partial and ordinary differential equations, with applications in biology, chemistry, engineering, me…
Validation tests of GBS quantum computers give evidence for quantum advantage with a decoherent target
Alexander S. Dellios, Bogdan Opanchuk, Margaret D. Reid +1
Computational validation is vital for all large-scale quantum computers. One needs computers that are both fast and accurate. Here we apply precise, scalable, high order statistica…
Simulating macroscopic quantum correlations in linear networks
A. Dellios, Peter D. Drummond, Bogdan Opanchuk +2
Many developing quantum technologies make use of quantum networks of different types. Even linear quantum networks are nontrivial, as the output photon distributions can be exponen…
Simulating complex networks in phase space: Gaussian boson sampling
Peter D. Drummond, Bogdan Opanchuk, Alexander Dellios +1
We show how phase-space simulations of Gaussian quantum states in a photonic network permit verification of measurable correlations of Gaussian boson sampling (GBS) quantum compute…
