An Optimal Analysis of the Product Test
Jacob Beckey, Fernando Granha Jeronimo, Pei Wu
Product testing, i.e., deciding whether a pure multipartite quantum state is fully unentangled across a specified tensor decomposition, serves as a bridge between quantum property…
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…
Localizing entanglement in high-dimensional states
Christopher Vairogs, Akanksha Chablani, Leo Lee +3
In this work, we study the asymptotic behavior of protocols that localize entanglement in large multi-qubit states onto a subset of qubits by measuring the remaining qubits. We use…
Impulse measurements enhanced with squeezed readout light
Tsai-Chen Lee, Jacob L. Beckey, Giacomo Marocco +1
We quantify how squeezed light can reduce quantum measurement noise to levels below the standard quantum limit in impulse measurements with mechanical detectors. The broadband natu…
