Mixed Signal Controller for Real-Time Quantum Sensor Measurements
Leveraging from our defense know-how, we partnered with a UK university to equip them with a modular, scalable real-time mixed signal control-system for their quantum sensor measurements. Suitable for quantum clocks and quantum gravity measurements, in each case the task of powering, controlling and stimulating the quantum sensor is complex. Precise timing of multiple events and adjusting behavior in real-time based on observed reactions is essential.
Our solution accommodates their current needs and is upgradeable for the future. It consists of rack-mount modules supplying many channels of microwave waveforms used to modulate and control lasers, power for magneto-optical traps (MOTs), channels of thermal measurement and many logic signals. At the center of the system is a real-time FPGA-based controller with very low latency and precisely characterized propagation delays. High level programming and non-time critical instructions are provided by a PC.
