Concatenated continuous driving of silicon qubit by amplitude and phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +22
The rate of coherence loss is lower for a qubit under the Rabi drive than a freely evolving qubit . Building on this principle, concatenated continuous d…

Optimal cavity design for minimizing errors in cavity-QED-based atom-photon entangling gates with finite temporal duration
Takeru Utsugi, Rui Asaoka, Yuuki Tokunaga +1
We investigate atom-photon entangling gates based on cavity quantum electrodynamics (QED) for a finite photon-pulse duration, where not only the photon loss but also the temporal m…

Gaussian-wavepacket-model for single-photon generation based on cavity QED in the adiabatic and nonadiabatic conditions
Takeru Utsugi, Akihisa Goban, Yuuki Tokunaga +2
For single-photon generation based on cavity quantum electrodynamics, we investigate a practical model assuming a Gaussian wavepacket. This model makes it possible to comprehensive…
