Three-qubit phase gate based on cavity quantum electrodynamics Academic Article uri icon


  • We describe a three-qubit quantum phase gate which is implemented by passing a four-level atom in a cascade configuration initially in its ground state through a three-mode optical cavity. The three qubits are represented by the photons in the three modes of the cavity. Under appropriate detunings, coupling coefficients, and interaction times, this system exhibits like a three-qubit quantum phase gate. Such a quantum phase gate has potential applications in quantum search. 2008 The American Physical Society.
