A two-way approach to out-of-time-order correlators

Yingfei Gu, Alexei Kitaev, Pengfei Zhang

Out-of-time-order correlators (OTOCs) are a standard measure of quantum chaos. Of the four operators involved, one pair may be regarded as a source and the other as a probe. A usua…

Observation of Time-Crystalline Eigenstate Order on a Quantum Processor

Xiao Mi, Matteo Ippoliti, Chris Quintana +102

Quantum many-body systems display rich phase structure in their low-temperature equilibrium states. However, much of nature is not in thermal equilibrium. Remarkably, it was recent…

Calculated Boldness: Optimizing Financial Decisions with Illiquid Assets

Stanislav Shalunov, Alexei Kitaev, Yakov Shalunov +1

We consider games of chance played by someone with external capital that cannot be applied to the game and determine how this affects risk-adjusted optimal betting. Specifically, w…

Quantum Algorithm for Spectral Measurement with Lower Gate Count

David Poulin, Alexei Kitaev, Damian S. Steiger +2

We present two techniques that can greatly reduce the number of gates required to realize an energy measurement, with application to ground state preparation in quantum simulations…

Interacting anyons in topological quantum liquids: The golden chain

Adrian Feiguin, Simon Trebst, Andreas W. W. Ludwig +4

We discuss generalizations of quantum spin Hamiltonians using anyonic degrees of freedom. The simplest model for interacting anyons energetically favors neighboring anyons to fuse…

Shot Noise in Anyonic Mach-Zehnder Interferometer

D. E. Feldman, Yuval Gefen, Alexei Kitaev +2

We show how shot noise in an electronic Mach-Zehnder interferometer in the fractional quantum Hall regime probes the charge and statistics of quantum Hall quasiparticles. The depen…
