AI Technical Summary

Technical Problem

QCCD-based quantum computers face throughput limitations due to the time required for transporting quantum objects within confinement devices, which hinders efficient quantum computation performance.

Method used

Implementing a pipeline delivery of entangled quantum objects and remote quantum logic operations to minimize transport latency, enabling high-throughput quantum computations by using entangled sets of e-bits that are transported and interact at minimal latency, allowing all-to-all connectivity without requiring data qubit transport.

Benefits of technology

Enhances the computational throughput of QCCD-based quantum computers by performing quantum computations on a throughput-limited timescale rather than a transport-latency-limited timescale, thereby improving the efficiency and speed of quantum logic operations.

Abstract

A multi-domain confinement device is provided. The multi-domain confinement device is configured for pipeline delivery of entangled sets of e-bits for use when performing remote quantum logic operations. The multi-domain confinement device includes an entangled domain comprising an entangled domain confinement device, a routing domain comprising one or more respective routing domain confinement devices, and an interaction domain comprising an interaction domain confinement device. The entangled domain defines one or more entangled locations, and the entangled domain is configured so that sets of e-bits are entangled in each entangled location. Each of the respective routing domain confinement devices and interaction domain confinement devices is configured so that quantum objects can pass through them in their respective inter-layer routing locations. The interaction domain defines multiple interaction locations, and the interaction domain is configured so that data qubit-e-bit pairs interact in each interaction location.
