Quantum Virtual Cooling
Jordan Cotler, Soonwon Choi, Alexander Lukin +10
We propose a quantum information based scheme to reduce the temperature of quantum many-body systems, and access regimes beyond the current capability of conventional cooling techn…
A Quantum Multiparty Packing Lemma and the Relay Channel
Dawei Ding, Hrant Gharibyan, Patrick Hayden +1
Optimally encoding classical information in a quantum system is one of the oldest and most fundamental challenges of quantum information theory. Holevo's bound places a hard upper…
Quantum Lyapunov Spectrum
Hrant Gharibyan, Masanori Hanada, Brian Swingle +1
We introduce a simple quantum generalization of the spectrum of classical Lyapunov exponents. We apply it to the SYK and XXZ models, and study the Lyapunov growth and entropy produ…
