MIT researchers develop device to enable direct communication between multiple quantum processors
CAMBRIDGE, Mass. - Quantum computers have the potential to solve complex problems that would be impossible for the most powerful classical supercomputer to crack. Just like a classical computer has separate, yet interconnected, components that must work together, such as a memory chip and a CPU on a motherboard, a quantum computer will need to communicate quantum information between multiple processors, Adam Zewe reorts for MIT News.

The Military & Aerospace Electronics take:
7 April 2025 -Their approach utilizes a superconducting waveguide to transfer microwave photons, which carry quantum information, between processors. By coupling multiple modules to this waveguide, they created a scalable network capable of efficiently transmitting data.
The team demonstrated remote entanglement—an essential step in building distributed quantum networks—by sending photons between two quantum processors. Each module, containing four qubits, can emit and absorb photons in a controlled direction using microwave pulses. Reversing the pulses allows a distant module to absorb the photon, creating quantum correlations between nonlocal qubits.
This breakthrough lays the groundwork for large-scale quantum computing networks and could extend to other quantum computing platforms and the quantum internet. The research, published in Nature Physics, was supported by the U.S. Army Research Office, AWS Center for Quantum Computing, and U.S. Air Force Office of Scientific Research.
