Wigner function negativity in a classical model of quantum light
Brian R. La Cour
The presence of negative values in the Wigner quasiprobability distribution is deemed one of the hallmarks of nonclassical phenomena in quantum systems. Here we demonstrate a class…
Gauging practical computational advantage using a classical, threshold-based Gaussian boson sampler
Sarvesh Raghuraman, Aditya Patwardhan, Brian La Cour
We describe an efficient, scalable Gaussian boson sampler based on a classical description of squeezed quantum light and a deterministic model of single-photon detectors that click…
An Adversarial Quantum Key Distribution Project
Brian R. La Cour, Noah A. Davis
Quantum key distribution (QKD) is a popular introduction to quantum technologies used in education and public outreach, as very little background in quantum theory is needed and th…
Definitive Proof of the Classical Multiverse!
Brian R. La Cour, Noah A. Davis
Recent astonishing experiments with quantum computers have demonstrated unambiguously the existence of a quantum multiverse, where calculations of mind-boggling complexity are effo…
Macroscopic Determinism in Interacting Systems Using Large Deviation Theory
Brian R. La Cour, William C. Schieve
We consider the quasi-deterministic behavior of systems with a large number, , of deterministically interacting constituents. This work extends the results of a previous paper […
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 General Conditional Large Deviation Principle
Brian R. La Cour, William C. Schieve
Given a sequence of Borel probability measures on a Hausdorff space which satisfy a large deviation principle, we consider the corresponding sequence of measures formed by conditio…
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…
A Decoder for the Color Code with Boundaries
Skylar Turner, Josey Hanish, Eion Blanchard +2
We introduce a decoder for the 3D color code with boundaries, which is a variation of the restriction decoder introduced by Kubicka and Delfosse. Specifically, we adapt the lift pr…
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…
