Quest for quantum advantage: Monte Carlo wave-function simulations of the Coherent Ising Machine
Manushan Thenabadu, Run Yan Teh, Jia Wang +3
The Coherent Ising Machine (CIM) is a quantum network of optical parametric oscillators (OPOs) intended to find ground states of the Ising model. This is an NP-hard problem, relate…
Non-periodic Fourier propagation algorithms for partial differential equations
Channa Hatharasinghe, Run Yan Teh, Jesse van Rhijn +2
Spectral methods for partial differential equations (PDEs) with non-periodic boundary conditions arising in computational physics often use polynomial expansions on non-uniform gri…
Q-based, objective-field model for wave-function collapse: Analyzing measurement on a macroscopic superposition state
Channa Hatharasinghe, Ashleigh Willis, Run Yan Teh +2
The measurement problem remains unaddressed in modern physics, with an array of proposed solutions but as of yet no agreed resolution. In this paper, we examine measurement using t…
Complexity order of multiple resource algorithms
Run Yan Teh, Manushan Thenabadu, Peter D Drummond
Algorithmic efficiency is essential to reducing energy and time usage for computational problems. Optimizing efficiency is important for tasks involving multiple resources, for exa…
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…
Resolving Schrödinger's analysis of the Einstein-Podolsky-Rosen paradox: an incompleteness criterion and weak elements of reality
C. McGuigan, R. Y. Teh, P. D. Drummond +1
The Einstein-Podolsky-Rosen (EPR) paradox was presented as an argument that quantum mechanics is an incomplete description of physical reality. However, the premises on which the a…
