Quantum circuit physical design flow for the multiplexed trap architecture

Abstract

Physical design is the second process in the design flow of quantum circuits that receives a netlist as input and generates a layout at a target technology. Quantum physical design problem is intractable. This process tackles the operation scheduling, placement, and qubit routing problems. Some approaches have been proposed for the physical design in ion trap technology that is currently one of the most advanced quantum technologies. These methods do not use all capabilities of the technology. Focusing on this issue, in this paper, a physical design flow is proposed for the multiplexed trap architecture utilizing the capabilities provided by the technology not considered by other approaches to improve the latency and area metrics. Experimental results show that the proposed approach decreases the average latency of quantum circuits by about 39.5% for the attempted benchmarks.
