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.

Disclosed is a system and method for solid-state 2D optical phased arrays (OPAs), which are fabricated from In-rich In.sub.1-xGa.sub.xN/GaN multiple quantum wells (MQWs). In-rich In.sub.xGa.sub.1-xN alloys possess the unique properties of exceptionally high free-carrier-induced refractive index (n) change and low optical loss. InGaN/GaN MQW pixels play the role of using a very small fraction of a laser beam to modulate the phase of the laser beam. The phase of each MQW pixel in the OPA is controlled independently via electro-optic effect through the integration between OPA pixels with a Laterally Diffused MOSFET (LDMOS) integrated circuit driver to achieve the manipulation of the distribution of optical power in the far field. The present invention is applicable to a wide range of applications, including the operation of LIDAR systems, laser weapons, laser illuminators, and laser imaging systems.
