Quantum Error Correction using Field Programmable Gate Array
Quantum Computing (QC) is an emerging area of almost infinite excitement and potential. Whilst the vision for QC is decades old, recent years have seen a slew of breakthroughs in the design of practical QCs and the development of commercial and prototype systems from D-Wave, Rigetti Computing, IBM, Microsoft, Google and many others.
As the development of practical QCs continues apace, a series of fundamental QC architecture challenges arise. One of the most critical of these is the practical realisation of Quantum Error Correction (QEC) for detecting and correcting errors in the measured stated of QC qubits. This has a strong influence on the capacity of a quantum processor, by determining the proportion of the processor’s qubits given over to useful operations. This in turn influences the scale of workloads practical quantum processors can process. QEC is also a time-critical step in dynamic quantum operations, which demand state-dependent consideration of the next step in the evolution of a quantum program.
A very substantial body of work has investigated QEC approaches for their error detection and correction capability and, sometimes, complexity. But practical realisation has not been meaningfully considered in any substantive sense. In many cases the complexity and real-time constraints on the QEC process demand the use of Field Programmable Gate Array (FPGA) devices for practical realisation. There is almost no evidence of any attempt to realise practical QEC approaches on FPGA, nor consideration of QEC approaches in the context of FPGA realisation.
This project addresses this problem. It will develop the first practical FPGA solution for QEC of modern and medium-term quantum processors. This project is an Engineering and Physical Sciences Research Council (EPSRC) Doctoral Training Partnership (DTP) in conjunction with Keysight Technologies. It will be conducted in close cooperation with Keysight Technologies, as they develop their first line of FPGA-based quantum computer test equipment.
