Simulation of Single-shot Qubit Readout of a 2-Qubit Superconducting System with Noise Analysis
2022 IEEE Latin American Electron Devices Conference (LAEDC)
It is desirable to reduce the readout time in a quantum computer so that more operations can be performed before decoherence occurs. In this paper, we propose and study a novel readout scheme of two qubits through simulations with a calibrated noise model. Two resonators with resonant frequencies only ~5MHz apart are designed and coupled to two superconducting qubits, respectively. A single shot readout is performed using one single frequency pulse to read the states of the two qubits. This has the potential to increase the number of qubits for a given bandwidth. The simulator used is written in Matlab which takes S21 calculated by Ansys HFSS as inputs. The know-how of performing repeatable and accurate simulations in HFSS is also discussed.
