Integrated reconfigurable quantum control system used to find electron-spin resonance (ESR) frequency and perform Rabi, Ramsey, and Hahn-echo measurements for a nitrogen-vacancy (NV) center spin qubit in diamond. 180 nm CMOS

1.6-2.6 GHz

On-chip microwave LC-VCO source is phase and frequency-locked to an external source. Moore Machine used for pulse sequence generation with four control bits for amplitude, width, phase and sign.

Quantum computers, communication links and sensors

Up to 4098 reconfigurable pulses with pulse widths from 10 ns to 42 ms and pulse-to-pulse delay from 18 ns to 42 ms at a resolution of 2.5 ns.
