Abstract
A novel and useful quantum computing machine includes classic computing and quantum computing cores. A programmable pattern generator executes instructions that control the quantum core. A pulse generator generates the control signals input to the quantum core to perform quantum operations. A partial readout of the quantum state is re-injected into the quantum core to extend decoherence time. Access gates control movement of quantum particles in the quantum core. Errors are corrected from the readout before being re-injected into the quantum core. Internal and external calibration loops calculate error syndromes and calibrate control pulses input to the quantum core. Control of the quantum core is provided from an external support unit via the pattern generator or retrieved from classic memory where sequences of commands are stored in memory. A cryostat unit functions to cool the quantum computing core to approximately 4 Kelvin.
