Effect of Decoherence for Gate Operations on a Superconducting Bosonic Qubit
Kosuke Mizuno, Takaaki Takenaka, Imran Mahboob +1
High-quality-factor 3D cavities in superconducting circuits are ideal candidates for bosonic logical qubits as their fidelity is limited only by the low photon loss rate. However,…
Magnetometry of neurons using a superconducting qubit
Hiraku Toida, Koji Sakai, Tetsuhiko F. Teshima +5
We demonstrate magnetometry of cultured neurons on a polymeric film using a superconducting flux qubit that works as a sensitive magnetometer in a microscale area. The neurons are…
A three-dimensional Josephson parametric amplifier
I. Mahboob, H. Toida, K. Kakuyanagi +2
A Josephson parametric amplifier (JPA) is executed in a three-dimensional (3D) microwave cavity by coupling it to a superconducting quantum interference device (SQUID) that is embe…
