Shift of quantum critical point of discrete time crystal on a noisy quantum simulator
Yuta Hirasaki, Toshinari Itoko, Naoki Kanazawa +1
Recent advances in quantum technology have enabled the simulation of quantum many-body systems on real quantum devices. However, such quantum simulators are inherently subject to d…
Dynamics of measurement-induced state transitions in superconducting qubits
Yuta Hirasaki, Shunsuke Daimon, Naoki Kanazawa +3
We have investigated temporal fluctuation of superconducting qubits via the time-resolved measurement for an IBM Quantum system. We found that the qubit error rate abruptly changes…
Three-qubit Parity Gate via Simultaneous Cross Resonance Drives
Toshinari Itoko, Moein Malekakhlagh, Naoki Kanazawa +1
Native multi-qubit parity gates have various potential quantum computing applications, such as entanglement creation, logical state encoding and parity measurement in quantum error…
