Controlled Phase Gate Based on an Electron Floating on Helium
Yan-Li Shi, Feng Mei, Ya-Fei Yu, Zhi‐Ming Zhang · Chinese Physics Letters · 2011
We propose a scheme to generate the controlled phase gate by using an electron floating on liquid helium. The electron is also driven by a classical laser beam and by an oscillating magnetic field. In the process, the vibration of the electron is used as the qubus to couple the energy level qubit (1D Stark-shifted hydrogen) and spin qubit. Ultimately, the controlled phase gate can be generated.
