High coherent solid-state qubit from a pair of quantum dots
Xin-Qi Li, YiJing Yan
abstract: In this letter we propose a scheme to build up high coherent solid-state
quantum bit (qubit) from two coupled quantum dots. Quantum information is
stored in electron-hole pair state with the electron and hole locating in
different dots, and universal quantum gates involving any pair of qubits are
realized by effective coupling interaction via virtually exchanging cavity
photons.
