Spin amplification in realistic systems
Ivan Iakoupov, Victor M. Bastidas, Yuichiro Matsuzaki +2
Spin amplification is the process that ideally increases the number of excited spins when one of them is excited initially. We show that by applying optimal control techniques to d…

Identifying impurities in a silicon substrate by using a superconducting flux qubit
Hiraku Toida, Kosuke Kakuyanagi, Leonid V. Abdurakhimov +3
A bismuth-doped silicon substrate was analyzed by using a magnetometer based on a superconducting flux qubit. The temperature dependence of the magnetization indicates that the sil…
