Product testing with single-copy measurements
Jacob Beckey, Luke Coffman, Ariel Shlosberg +2
In this work, we study the sample complexity of two variants of product testing when restricted to single-copy measurements. In particular, we consider both bipartite product testi…

High-Distance Error-Correcting Codes for Fermion-to-Qubit Mappings in 2D and 3D
Ruby Wei, Aqua Chung, Luke Coffman +2
Quantum simulation of fermionic systems is a leading application of quantum computers. One promising approach is to represent fermions with qubits via fermion-to-qubit mappings. In…

Measuring Non-Gaussian Magic in Fermions: Convolution, Entropy, and the Violation of Wick's Theorem and the Matchgate Identity
Luke Coffman, Graeme Smith, Xun Gao
Classically hard to simulate quantum states, or "magic states", are prerequisites to quantum advantage, highlighting an apparent separation between classically and quantumly tracta…
