Classical Attack on Bell Inequalities
Aishi Guha, Noah A. Davis, Brian R. La Cour
Representing multi-mode squeezed light with a Gaussian random vector, our locally deterministic detection model challenges the CHSH game, achieving fidelities exceeding 96\%. Squee…
Classical model of quantum interferometry tests of macrorealism
Brian R. La Cour
Macrorealism is a characteristic feature of many, but not all, classical systems. It is known, for example, that classical light can violate a Leggett-Garg inequality and, hence, r…
Quantum contextuality in the Mermin-Peres square: A hidden variable perspective
Brian R. La Cour
The question of a hidden variable interpretation of quantum contextuality in the Mermin-Peres square is considered. The Kochen-Specker theorem implies that quantum mechanics may be…
Classical emulation of a quantum computer
Brian R. La Cour, Corey I. Ostrove, Granville E. Ott +2
This paper describes a novel approach to emulate a universal quantum computer with a wholly classical system, one that uses a signal of bounded duration and amplitude to represent…
A local hidden-variable model for experimental tests of the GHZ puzzle
Brian R. La Cour
The Greenberger-Horne-Zeilinger (GHZ) puzzle has been used to study quantum nonlocality and provide an all-or-nothing, no-go theorem for local hidden-variable models. Recent experi…
Classical Simulated Annealing Using Quantum Analogues
Brian R. La Cour, James E. Troupe, Hans M. Mark
In this paper we consider the use of certain classical analogues to quantum tunneling behavior to improve the performance of simulated annealing on a discrete spin system of the ge…
Quantum decoherence emulated in a classical device
Brian R. La Cour, Corey I. Ostrove, Michael J. Starkey +1
We demonstrate that a classical emulation of quantum gate operations, here represented by an actual analog electronic device, can be modeled accurately as a quantum operation in te…
Classical model for measurements of an entanglement witness
Brian R. La Cour, E. C. George Sudarshan
We describe a classical model that may serve as an analog for joint and local measurements of an entanglement witness. The analogous experimental procedure and data analysis protoc…
A locally deterministic, detector-based model of quantum measurement
Brian R. La Cour
This paper describes a simple, causally deterministic model of quantum measurement based on an amplitude threshold detection scheme. Surprisingly, it is found to reproduce many phe…
Subspace projection method for unstructured searches with noisy quantum oracles using a signal-based quantum emulation device
Brian R. La Cour, Corey I. Ostrove
This paper describes a novel approach to solving unstructured search problems using a classical, signal-based emulation of a quantum computer. The classical nature of the represent…
Signal-based classical emulation of a universal quantum computer
Brian R. La Cour, Granville E. Ott
In this paper we present a novel approach to emulating a universal quantum computer with a classical system, one that uses a signal of bounded duration and amplitude to represent a…
Classical model of delayed-choice quantum eraser
Brian R. La Cour, Thomas W. Yudichak
Wheeler's delayed-choice experiment was conceived to illustrate the paradoxical nature of wave-particle duality in quantum mechanics. In the experiment, quantum light can exhibit e…
Entanglement and Impropriety
Brian R. La Cour, Thomas W. Yudichak
The relationship between quantum entanglement and classical impropriety is considered in the context of multi-modal squeezed states of light. Replacing operators with complex Gauss…
Emergence of the Born rule in quantum optics
Brian R. La Cour, Morgan C. Williamson
The Born rule provides a fundamental connection between theory and observation in quantum mechanics, yet its origin remains a mystery. We consider this problem within the context o…
Improving Performance of an Analog Electronic Device Using Quantum Error Correction
Corey Ostrove, Brian La Cour, Andrew Lanham +1
The use of analog classical systems for computation is generally thought to be a difficult proposition due to the susceptibility of these devices to noise and the lack of a clear f…
Parallel Quantum Computing Emulation
Brian R. La Cour, S. Andrew Lanham, Corey I. Ostrove
Quantum computers provide a fundamentally new computing paradigm that promises to revolutionize our ability to solve broad classes of problems. Surprisingly, the basic mathematical…
Asymmetric delay attack on an entanglement-based bidirectional clock synchronization protocol
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate an attack on a clock synchronization protocol that attempts to detect tampering of the synchronization channel using polarization-entangled photon pairs. The protoco…
Detecting Optical Channel Non-Reciprocity with Non-Local Quantum Geometric Phase
James E Troupe, Antia Lamas-Linares
Non-reciprocal devices are of increasing interest in quantum information technologies. This paper examines whether the presence of a non-reciprocal device in an optical channel is…
Local hidden-variable model for a recent experimental test of quantum nonlocality and local contextuality
Brian R. La Cour
An experiment has recently been performed to demonstrate quantum nonlocality by establishing contextuality in one of a pair of photons encoding four qubits; however, low detection…
Heisenberg scaling with weak measurement: A quantum state discrimination point of view
Andrew N. Jordan, Jeff Tollaksen, James E. Troupe +2
We examine the results of the paper "Precision metrology using weak measurements", [Zhang, Datta, and Walmsley, arXiv:1310.5302] from a quantum state discrimination point of view.…
