摘要: We propose a method to prepare entangled states and implement quantum computation with atoms in optical cavities. The internal of the are by measurement phase light transmitted through cavity. By repeated measurements an state is created certainty, this entanglement can be used gates on qubits which stored different degrees freedom atoms. This method, based induced dynamics, has higher fidelity than schemes making use controlled unitary dynamics.
