Freezing electronics to control diamond spin qubits

"enabling larger quantum computers overcoming wiring bottleneck... freeze diamond spin qubits and controls (instead of just qubits) in single compact energy efficient cryo-CMOS refrigerator without sacrificing performance and scalability... fewer wires... diamond enables better fidelity, more easily remotely connected with each other, at (relatively) higher temperature... generally scaling up to a larger quantum processors"
