Diffusion model for analyzing quantum fingerprints in conductance fluctuation
Naoto Yokoi, Yuki Tanaka, Yukito Nonaka +3
A conditional diffusion model has been developed to analyze intricate conductance fluctuations called universal conductance fluctuations or quantum fingerprints appearing in quantu…
Negative longitudinal resistance of monolayer graphene in the quantum Hall regime
Alexey A. Kaverzin, Shunsuke Daimon, Takashi Kikkawa +2
In the quantum Hall regime the charge current is carried by ideal one-dimensional edge channels where the backscattering is prohibited by topology. This results in the constant pot…
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…
Detecting bulk carbon ferromagnetism in graphene multi-edge structure
Chao Wang, Nan Jian, Meijie Yin +11
The emergence of bulk carbon ferromagnetism is long-expected over years. At nanoscale, carbon ferromagnetism was detected by analyzing the magnetic edge states via scanning tunneli…
Quantum Circuit Distillation and Compression
Shunsuke Daimon, Kakeru Tsunekawa, Ryoto Takeuchi +3
Quantum coherence in a qubit is vulnerable to environmental noise. When long quantum calculation is run on a quantum processor without error correction, the noise often causes fata…
Detection of temporal fluctuation in superconducting qubits for quantum error mitigation
Yuta Hirasaki, Shunsuke Daimon, Toshinari Itoko +2
We have investigated instability of a superconducting quantum computer by continuously monitoring the qubit output. We found that qubits exhibit a step-like change in the error rat…
