Constraints on recovering quantum information after erasure
Mohammad A. Alhejji, Noah Lordi, Omkar Baraskar +2
Suppose that we encode quantum information into physical carriers. With what probabilities can we perfectly recover the quantum information after sets of carriers have been e…
Robust Negativity in the Quantum-to-Classical Transition of Kerr Dynamics
Mohsin Raza, John B. DeBrota, Ariel Shlosberg +2
We quantify the quantum-to-classical transition of the single-mode Kerr nonlinear dynamics in the presence of loss. We establish three time scales that govern the dynamics, each wi…
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…
Efficient simulation of noisy IQP circuits with amplitude-damping noise
Shravan Shravan, Mohsin Raza, Ariel Shlosberg
Efficient classical simulation of noisy intermediate-scale quantum (NISQ) circuits has been a topic of intense study over the past few years. The majority of results on efficient s…
Uniform Additivity of Tripartite Optimized Correlation Measures
Joshua Levin, Ariel Shlosberg, Vikesh Siddhu +1
Information theory provides a framework for answering fundamental questions about the optimal performance of many important quantum communication and computational tasks. In many c…
