Methods and apparatuses for multipurpose light collection for remotely entangling atomic quantum computers in a multi-core architecture

Abstract

Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to systems and methods for receiving a readout beam associated with a state of a first qubit of an array of trapped ions, receiving an interconnect beam configured entangle a second qubit of the array with an external qubit of an external array, receiving an addressing beam, from an addressing unit, configured to control a state of a third qubit of the array, guiding, via at least one switch, the addressing beam from the addressing unit toward the third qubit, guiding, via the at least one switch, the readout beam toward a photodetector, and guiding, via the at least one switch, the interconnect beam toward an interconnect unit optically coupled with the external array.

Dependencies are inferred from the claim text.
