Physical currents for stochastic Einstein-Podolsky-Rosen quantum trajectories
R. Y. Teh, M. Thenabadu, P. D. Drummond +1
Theories of the measured homodyne current generated by a stochastic Schrödinger equation (SSE) can be tested in a simulation of the Einstein-Podolsky-Rosen (EPR) correlations for a…
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…
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…
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…
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…
Wigner's Friend paradoxes: consistency with weak-contextual and weak-macroscopic realism models
Ria Joseph, Manushan Thenabadu, Channa Hatharasinghe +4
Wigner's friend paradoxes highlight contradictions between measurements made by Friends inside a laboratory and superobservers outside a laboratory, who have access to an entangled…
Macroscopic delayed-choice and retrocausality: quantum eraser, Leggett-Garg and dimension witness tests with cat states
Manushan Thenabadu, M. D. Reid
We propose delayed choice experiments carried out with macroscopic qubits, realised as macroscopically-distinct coherent states and . Quantum superpositions…
Bipartite Leggett-Garg and macroscopic Bell inequality violations using cat states: distinguishing weak and deterministic macroscopic realism
Manushan Thenabadu, M. D. Reid
We consider tests of Leggett-Garg's macrorealism and of macroscopic local realism, where for spacelike separated measurements the assumption of macroscopic noninvasive measurabilit…
Weak versus deterministic macroscopic realism, and Einstein-Podolsky-Rosen's elements of reality
Jesse Fulton, M. Thenabadu, Run Yan Teh +1
Violation of Leggett-Garg inequalities allows proof of the incompatibility between quantum mechanics and the combined premises (called macrorealism) of macroscopic realism (MR) and…
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…
Testing macroscopic local realism using cat-states and Bell inequalities in time
M. Thenabadu, G-L. Cheng, T. L. H. Pham +3
We show how one may test macroscopic local realism where, different from conventional Bell tests, all relevant measurements need only distinguish between two macroscopically distin…
Leggett-Garg tests of macro-realism for dynamical cat-states evolving in a nonlinear medium
Manushan Thenabadu, Margaret Reid
We show violations of Leggett-Garg inequalities to be possible for single-mode cat-states evolving dynamically in the presence of a nonlinear quantum interaction arising from, for…
