研究課題
Our research has focused on advancing fast, high-fidelity readout in superconducting quantum computers. Achievements include designing and patenting a novel ‘Purcell’ filter, integrating the design into the superconducting circuit architecture being pursued at RIKEN, and demonstrating state-of-the-art high-fidelity readout surpassing previous benchmarks. Our readout results pave the way for effective implementation of quantum error correction in the superconducting circuits under development at RIKEN.
1: 当初の計画以上に進展している
At the current stage, I have designed and measured a device that sets a new record for performing accurate readout using superconducting qubits. Myself and the coauthors are writing a manuscript about this device which we plan to submit to an APS journal such as Physical Review Applied. The device features a new design of ‘Purcel filter’ that protects the qubit from losing its energy through the measurement line. We have filed a patent application for this design. I have also developed theoretical results along with coauthor Shuhei Tamate on the behavior of periodic quantum circuits at large-scale. We aim to prepare a manuscript on these results.
The current plan is as follows:-Finish measuring the current device and demonstrate state-of-the-art readout performance. Submit a manuscript based on these measurements.-Write a separate manuscript based on modelling the behavior of periodic quantum circuits at large-scale.-Contribute to a collaboration with University of Oxford researchers on improved superconducting qubit readout state discrimination using a novel machine-learning approach.I anticipate it will be possible to compete this plan before the end of the JSPS fellowship on 21st November 2024.
