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…
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…
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…
Recovering Quantum Information in Orbital Angular Momentum of Photons by Adaptive Optics
Jose Raul Gonzalez Alonso, Todd Brun
Orbital angular momentum of photons is an intriguing system for the storage and transmission of quantum information, but it is rapidly degraded by atmospheric turbulence. We explor…
Error correction with orbital angular momentum of multiple photons propagating in a turbulent atmosphere
Jose Raul Gonzalez Alonso, Todd Brun
Orbital angular momentum of photons is an intriguing system for the storage and transmission of quantum information, but it is rapidly degraded by atmospheric turbulence. Understan…
Protecting weak measurements against systematic errors
Shengshi Pang, Jose Raul Gonzalez Alonso, Todd A. Brun +1
In this work, we consider the systematic error of quantum metrology by weak measurements under decoherence. We derive the systematic error of maximum likelihood estimation in gener…
Protecting OAM Photons from Decoherence in a Turbulent Atmosphere
Jose Raul Gonzalez Alonso, Todd Brun
One of the most important properties of orbital angular momentum (OAM) of photons is that the Hilbert space required to describe a general quantum state is infinite dimensional. In…
