C*-like modules and matrix -operator norms
Alessandra Calin, Ian Cartwright, Luke Coffman +5
We present a generalization of Hölder duality to algebra-valued pairings via -modules. Hölder duality states that if and are conjugate expon…
Local measurement strategies for multipartite entanglement quantification
Luke Coffman, Akshay Seshadri, Graeme Smith +1
Despite multipartite entanglement being a global property of a quantum state, a number of recent works have made it clear that it can be quantified using only local measurements. T…
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…
Group Fourier filtering of quantum resources in quantum phase space
Luke Coffman, N. L. Diaz, Martin Larocca +2
Recently, it has been shown that group Fourier analysis of quantum states, i.e., decomposing them into the irreducible representations (irreps) of a symmetry group, enables new way…
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…
Geometric Invariants of Quantum Metrology
Christopher Wilson, John Drew Wilson, Luke Coffman +2
We establish a previously unexplored conservation law for the Quantum Fisher Information Matrix (QFIM) expressed as follows; when the QFIM is constructed from a set of observables…
