Quantum Instruction Set Architecture (QUASAR) 2021-061
Anastasiia Butko at Berkeley Lab has developed a new ISA interface between the software program (quantum circuit) and hardware (generation of the gates).
The proposed quantum ISA (QUASAR) has been designed as an extension to the RISC-V ISA. The design implementation relies on the basic functionalities of the conventional ISA. Butko described an evaluation methodology towards efficient quantum ISA designs and designed the ISA specification baseline with a suitable combination of operations for future scalability and parallelism. Then, she physically implemented the designed ISA using Hardware Description Languages (HDL). The ISA (processor) can be fully used with software support.
