A quantum game of telephone
Arefur Rahman, Matthew L. Stevens, Cory M. Nunn +3
Characterizing multinode quantum networks without ubiquitous local entanglement sources presents significant experimental challenges. We introduce ``quantum telephone,'' an iterati…
Structured Factorization Approaches for Quantum State Tomography
Zhen Qin, Joseph M. Lukens, Brian T. Kirby +1
Since the complexity of quantum state tomography (QST) scales exponentially with system size, exploiting priors such as low-rankness, tensor-network structures, and neural-network…
Re-examining the Role of State Texture in Gate Identification and Fixed-Point Resource Theories
Alexander C. B. Greenwood, Joseph M. Lukens, Li Qian +1
A protocol for identifying controlled-NOT (CNOT) gates versus single-qubit-only gates in universal quantum circuits using randomized input states was recently shown to be intimatel…
Comparing Homodyne and Heterodyne Tomography of Quantum States of Light
Rhea P. Fernandes, Andrew J. Pizzimenti, Christos N. Gagatsos +1
Non-Gaussian quantum states are critical resources in photonic quantum information processing, rendering their generation and characterization of increasing importance in quantum o…
In situ quantum verification of polarization-stabilized optical channels
Matthew L. Stevens, Noah I. Wasserbeck, Zachary Goisman +8
The active stabilization of polarization channels is a task of growing importance as quantum networks move to deployed demonstrations over existing fiber infrastructure. However, t…
