Interconnect Fabrics for Multi-Core Quantum Processors

Abstract

Quantum computing has revolutionized the field of computer science with its extraordinary ability to handle classically intractable problems. To realize its potential, however, quantum computers need to scale to millions of qubits, a feat that will require addressing fascinating yet extremely challenging interconnection problems. In this paper, we provide a context analysis of the nascent quantum computing field from the perspective of communications, with the aim of encouraging the on-chip networks community to contribute and pave the way for truly scalable quantum computers in the decades to come.

Atomic Quantum Technologies for Quantum Matter and Fundamental Physics Applications

“…Architecture scalability, the ability to scale up the number of qubits and interconnect different quantum platforms, often necessitates the interconnection of many Quantum Processor Units (QPUs), that may also differ in terms of experimental realization [444].…”
