An FPGA-Based Hardware Platform for the Control of Spin-Based Quantum Systems
This paper reports the development of a highly efficient, flexible hardware platform, which is suitable for the control of spin-based quantum systems including quantum computation and quantum metrology. A 2-channel arbitrary waveform generator (AWG), an 8-channel pulse/sequence generator, a 2-channel Analog to Digital Converter (ADC), and a 2-channel high speed Time to Digital Converter (TDC) are fully integrated on a Printed Circuit Board (PCB). The AWG has a 1 GSa/s sampling rate and a 16-bit amplitude resolution. The pulse/ sequence generator can continuously output pulse/sequence signals with a 50 ps time resolution and a dynamic range from 5 ns to 2 seconds. The ADC provides a 1 GSa/s sampling rate and a 12-bit amplitude resolution for analog signal acquisition. The TDC provides a 6 ps time resolution and a maximum sampling frequency of 125 MHz. All these modules are realized utilizing a Field Programmable Gate Array (FPGA). Customized data calculation modules are also implemented with the FPGA logic. The hardware was tested and implemented in a pulsed Electron Spin Resonance (ESR) spectrometer and an Optically Detected Magnetic Resonance (ODMR) spectrometer.
