Researchers at MIT and MITRE have brought the goal of practical quantum computing nearer by developing a modular fabrication process to produce a quantum-system-on-chip (QSoC). Notably, diamond color centers were chosen for qubits because of their scalability advantages. Also, diamond color centers have photonic interfaces. In other words, they can interact with and manipulate photons. This allows them to be remotely entangled with distant qubits.
