Diagnosing quantum chaos with out-of-time-ordered-correlator quasiprobability in the kicked-top model
José Raúl González Alonso, Nathan Shammah, Shahnawaz Ahmed +2
While classical chaos has been successfully characterized with consistent theories and intuitive techniques, such as with the use of Lyapunov exponents, quantum chaos is still poor…
Failed attempt to escape from the quantum pigeon conundrum
Yakir Aharonov, Shrobona Bagchi, Justin Dressel +3
A recent criticism by Kunstatter et al. [Phys. Lett. A 384, 126686 (2020)] of a quantum setup violating the pigeon counting principle [Aharonov et al. PNAS 113, 532 (2016)] is refu…
Footprints of quantum pigeons
Gregory Reznik, Shrobona Bagchi, Justin Dressel +1
We show that in the mathematical framework of the quantum theory the classical pigeonhole principle can be violated more directly than previously suggested, i.e., in a setting clos…
Strongly measuring qubit quasiprobabilities behind out-of-time-ordered correlators
Razieh Mohseninia, José Raúl González Alonso, Justin Dressel
Out-of-time-ordered correlators (OTOCs) have been proposed as a tool to witness quantum information scrambling in many-body system dynamics. These correlators can be understood as…
Always-On Quantum Error Tracking with Continuous Parity Measurements
Razieh Mohseninia, Jing Yang, Irfan Siddiqi +2
We investigate quantum error correction using continuous parity measurements to correct bit-flip errors with the three-qubit code. Continuous monitoring of errors brings the benefi…
Benchmarks of Nonclassicality for Qubit Arrays
Mordecai Waegell, Justin Dressel
We present a set of practical benchmarks for -qubit arrays that economically test the fidelity of achieving multi-qubit nonclassicality. The benchmarks are measurable correlator…
