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…
The Case of the Missing Gates: Complexity of Jackiw-Teitelboim Gravity
Adam R. Brown, Hrant Gharibyan, Henry W. Lin +3
The Jackiw-Teitelboim (JT) model arises from the dimensional reduction of charged black holes. Motivated by the holographic complexity conjecture, we calculate the late-time rate o…
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…
Falling Toward Charged Black Holes
Adam R. Brown, Hrant Gharibyan, Alexandre Streicher +3
The growth of the "size" of operators is an important diagnostic of quantum chaos. In arXiv:1802.01198 [hep-th] it was conjectured that the holographic dual of the size is proporti…
Onset of Random Matrix Behavior in Scrambling Systems
Hrant Gharibyan, Masanori Hanada, Stephen H. Shenker +1
The fine grained energy spectrum of quantum chaotic systems is widely believed to be described by random matrix statistics. A basic scale in such a system is the energy range over…
