MIT News  May 29, 2024 Colour centres in diamond have emerged as a leading solid-state platform for advancing quantum technologies and recently achieved quantum advantage in secret key distribution. Blueprint studies indicate that general-purpose quantum computing using local quantum communication networks will require millions of physical qubits to encode thousands of logical qubits, presenting an open scalability challenge. An international team of researchers (MIT, DEVCOM, Army Research Laboratory, The MITRE Corporation, Cornell University, the Netherlands, Germany) introduced a modular quantum system-on-chip (QSoC) architecture that integrated thousands of individually addressable tin-vacancy spin qubits in two-dimensional arrays of quantum microchiplets into an […]
