Electron paramagnetic resonance spectroscopy using a dc-SQUID magnetometer directly coupled to an electron spin ensemble
Hiraku Toida, Yuichiro Matsuzaki, Kosuke Kakuyanagi +5
We demonstrate electron spin polarization detection and electron paramagnetic resonance (EPR) spectroscopy using a direct current superconducting quantum interference device (dc-SQ…
Engineering entangled microwave photon states via multiphoton interactions between two cavity fields and a superconducting qubit
Yan-Jun Zhao, Chang-Qing Wang, Xiaobo Zhu +1
It has been shown that there are not only transverse but also longitudinal couplings between microwave fields and a superconducting qubit with broken inversion symmetry of the pote…
Improving the lifetime of the NV center ensemble coupled with a superconducting flux qubit by applying magnetic fields
Yuichiro Matsuzaki, Xiaobo Zhu, Kosuke Kakuyanagi +8
One of the promising systems to realize quantum computation is a hybrid system where a superconducting flux qubit plays a role of a quantum processor and the NV center ensemble is…
