CREATION OF A MAXIMALLY ENTANGLED QUANTUM STATE

摘要

Embodiments are directed to engineering a structure, comprising: measuring energy eigenstates of a Hamiltonian, predicting a time evolution of a combination of two energy eigenstates based on the measurement, and creating an entangled quantum state for two coefficients of the two energy eigenstates such that an associated wavefunction is encouraged to undergo the predicted time evolution.

1. A method for engineering an optical quantum computing structure, comprising:
etching a plurality of gaps in an electro-optical slab to define a plurality of fingers that extend between a first horizontal side and a second horizontal side of the electro-optical slab, the plurality of fingers constructed from an electro-optical material coupled to a plurality of optical feed lines to form a respective waveguide; disposing a semiconductor quantum well structure at a first vertical surface of the electro-optical slab; outputting light from the plurality of fingers along a first axis to strike at least one layer of the semiconductor quantum well structure and generate a spectrum of energy transitions; applying an electric field to the electric field electrodes along a second axis perpendicular to the first axis; measuring energy eigenstates of a Hamiltonian of the optical quantum computing structure in response to recording the spectrum of energy transitions; predicting a time evolution of a combination of two energy eigenstates of the optical quantum computing structure based on the measurement; and controlling the electric field to create an entangled quantum state for two coefficients of the two energy eigenstates such that an associated wavefunction is encouraged to undergo the predicted time evolution.
