Quantum State Preparation

Popis výsledku v původním jazyce

A method of encoding a target state on a quantum system, the method comprising: providing, to a classical computer, a time-dependent Schrödinger equation characterising the properties of the quantum system, wherein the Schrödinger equation has a potential term, V, wherein boundary conditions providing constraints on solutions are included in the Schrödinger equation, and wherein a control parameter η is provided which allows control of the form of a potential term V, and/or a momentum operator; providing to the classical computer a description of the target state, to be encoded on the quantum system; formulating a time-domain optimisation problem in which the control parameter as a controllable variable to minimise a between a time-varying state of the quantum system, and the target state after a finite time T has elapsed, subject to the limitations imposed by the Schrödinger equation, the boundary conditions, and the initial state of the quantum system; transforming the time-domain optimisation problem into the frequency domain; solving the frequency-domain optimisation problem to identify a form of the control parameter which drives the quantum system into the target state within time T; using the identified form of the control parameter to form a pulse to vary V; and/or the momentum operator; and applying the pulse to the quantum system to drive the quantum system into the target state.
