The fate of the false vacuum: Finite temperature, entropy and topological phase in quantum simulations of the early universe
King Lun Ng, Bogdan Opanchuk, Manushan Thenabadu +2
Despite being at the heart of the theory of the "Big Bang" and cosmic inflation, the quantum field theory prediction of false vacuum tunneling has not been tested. To address the e…
Initial states and apodisation for quantum field simulations in phase-space
Peter D. Drummond
Bosonic quantum fields can be simulated with `quantum software' in phase-space. The positive-P, Wigner and Q-function phase-space methods are reviewed. Initial quantum states and b…
Nonlocal pair correlations in a higher-order Bose gas soliton
King Lun Ng, Bogdan Opanchuk, Margaret D. Reid +1
The truncated Wigner and positive-P phase-space representations are used to study the dynamics of a one-dimensional Bose gas. This allows calculations of the breathing quantum dyna…
Phase-space representations of thermal Bose-Einstein condensates
King Ng, Rodney Polkinghorne, Bogdan Opanchuk +1
Phase-space methods allow one to go beyond the mean-field approximation to simulate the quantum dynamics of interacting fields. Here, we obtain a technique for initializing either…
Simulating and assessing boson sampling experiments with phase-space representations
Bogdan Opanchuk, Laura Rosales-Zarate, Margaret D Reid +1
The search for new, application-specific quantum computers designed to outperform any classical computer is driven by the ending of Moore's law and the quantum advantages potential…
One-dimensional Bose gas dynamics: breather relaxation
Bogdan Opanchuk, Peter D. Drummond
One-dimensional Bose gases are a useful testing-ground for quantum dynamics in many-body theory. They allow experimental tests of many-body theory predictions in an exponentially c…
