How Time Works in Quantum Systems: Overview of time ordering and time correlation in weakly perturbed atomic collisions and in strongly perturbed qubits
J. H. McGuire, L. Kaplan, Kh. Kh. Shakov +5
Time ordering may be defined by first defining the limit of no time ordering (NTO) in terms of a time average of an external interaction, V(t). Previously, time correlation was def…
An overview of simply pulsed qubits
A. Chalastaras, L. Kaplan, Kh. Kh. Shakov +2
The behavior of simply pulsed qubits (quantum systems with two linearly independent states) may be characterized by the energy difference between the two states of the qubit a…
Sudden switching in qubits
Kh. Kh. Shakov, J. H. McGuire, L. Kaplan +2
Analytic solutions are developed for two-state systems (e.g. qubits) strongly perturbed by a series of rapidly changing pulses, called `kicks'. The evolution matrix may be expresse…
Time Ordering in Kicked Qubits
L. Kaplan, Kh. Kh. Shakov, A. Chalastaras +3
We examine time ordering effects in strongly, suddenly perturbed two-state quantum systems (kicked qubits) by comparing results with time ordering to results without time ordering.…
Quantum time ordering and degeneracy. I: Time ordering in quantum mechanics
J. H. McGuire, A. L. Godunov, Kh. Kh. Shakov +2
We examine how time ordering works in quantum mechanics and in classical mechanics.
Quantum time ordering and degeneracy. II: Coherent population transfer between degenerate states
Kh. Yu. Rakhimov, Kh. Kh. Shakov, J. H. McGuire
We find conditions required to achieve complete population transfer, via coherent population trapping, from an initial state to a designated final state at a designated time in a d…
