Transmission of quantum information through quantum fields in curved spacetimes
Michael Kasprzak, Erickson Tjoa
We construct a relativistic quantum communication channel between two localized qubit systems, mediated by a relativistic quantum field, that can achieve the theoretical maximum fo…

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…

Efficient Hamiltonian encoding algorithms for extracting quantum control mechanism as interfering pathway amplitudes in the Dyson series
Erez Abrams, Michael Kasprzak, Gaurav Bhole +2
Hamiltonian encoding is a methodology for revealing the mechanism behind the dynamics governing controlled quantum systems. In this paper, following Mitra and Rabitz [Phys. Rev. A…
