Controlled Phase Gate of Spin Qubits in Two Quantum-Dot Single-Photon Emitters

We show that a controlled phase gate on two laterally positioned quantum dots can be achieved using the long-range Coulomb coupling. The permanent dipole moment in piezoelectric quantum dots can significantly enhance the coupling. (C) 2021 The Author(s)
