Analysis of the spectroscopy of a hybrid system composed of a superconducting flux qubit and diamond NV centers
H. Cai, Y. Matsuzaki, K. Kakuyanagi +8
A hybrid system that combines the advantages of a superconducting flux qubit and an electron spin ensemble in diamond is one of the promising devices to realize quantum information…
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…
Ising interaction between capacitively-coupled superconducting flux qubits
Takahiko Satoh, Yuichiro Matsuzaki, Kosuke Kakuyanagi +3
Here, we propose a scheme to generate a controllable Ising interaction between superconducting flux qubits. Existing schemes rely on inducting couplings to realize Ising interactio…
Scalable quantum computation architecture using always-on Ising interactions via quantum feedforward
Takahiko Satoh, Yuichiro Matsuzaki, Kosuke Kakuyanagi +4
Here, we propose a way to control the interaction between qubits with always-on Ising interaction. Unlike the standard method to change the interaction strength with unitary operat…
