Role of Wireless Technology in Electromagnetic Nanonetworks for Quantum Computers

Investigate the role and feasibility of wireless electromagnetic links in modular quantum computers, specifically for terahertz backscatter-based contactless readout between host systems and quantum cores and for classical orchestration of inter-core quantum state transfers, determining achievable latency, throughput, and integration constraints under cryogenic operation.

Background

The paper discusses multi-core quantum architectures requiring both classical and quantum communications, noting that RF signals are widely used for control and readout. It highlights proposals for terahertz backscatter readout and for using wireless links to orchestrate classical communication for inter-core quantum transfers.

However, the authors state that the role of wireless technology in such electromagnetic nanonetworks for quantum computers is yet unclear, motivating a focused investigation into where and how wireless can be employed effectively within cryogenic quantum systems.
