Modular Architectures and Entanglement Schemes for Error-Corrected Distributed Quantum Computation

Understand

Connecting multiple smaller qubit modules by generating high-fidelity entangled states is a promising path for scaling quantum computing hardware.

• The performance of such a modular quantum computer is highly dependent on the quality and rate of entanglement generation.
• However, the optimal architectures and entanglement generation schemes are not yet established.
• Focusing on modular quantum computers with solid-state quantum hardware, we investigate a distributed surface code's error-correcting threshold and logical failure rate.
