Quantum Networks and Distributed Quantum Computing

Interdisciplinary Areas: Micro-, Nano-, and Quantum Engineering

Project Description

Quantum computing represents a paradigm shift in computational capabilities, offering solutions to problems beyond the reach of classical computers. Due to the inherent physical constraints, achieving full connectivity in a local quantum computer, especially one with a large number of qubits, poses a significant challenge. Distributed Quantum Computing (DQC) offers a scalable alternative by linking numerous small-scale, cost-effective local quantum computers, thus amplifying their collective computational power beyond boundary. In this project, we aim to develop quantum hardware modules and network architectures enabling DQC among various quantum computing platforms, such as photons or microwave, neutral atoms, trapped ions and superconductor circuits.
