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…
Out-of-Time-Ordered-Correlator Quasiprobabilities Robustly Witness Scrambling
José Raúl González Alonso, Nicole Yunger Halpern, Justin Dressel
Out-of-time-ordered correlators (OTOCs) have received considerable recent attention as qualitative witnesses of information scrambling in many-body quantum systems. Theoretical dis…
Strengthening weak measurements of qubit out-of-time-order correlators
Justin Dressel, José Raúl González Alonso, Mordecai Waegell +1
For systems of controllable qubits, we provide a method for experimentally obtaining a useful class of multitime correlators using sequential generalized measurements of arbitrary…
