Temporal Entanglement and Witnesses of Non-Classicality
Giuseppe Di Pietra, Gaurav Bhole, James Eaton +4
The universality of quantum theory has been questioned ever since it was proposed. Key to this long-unsolved question is to test whether a given physical system has non-classical f…
Mechanism behind creating qubit gates expressed as interfering quantum pathway amplitudes
Michael Kasprzak, Gaurav Bhole, Herschel Rabitz
Hamiltonian encoding was introduced as a technique for revealing the mechanism of controlled quantum systems. It does so by decomposing the evolution into pathways between the comp…
