quantum Trajectory Equation for multiple qubits in circuit qed generating entanglement by measurement
CaJPh, 2009Co-Authors: Chantal L Hutchison, Jay M Gambetta, Alexandre Blais, Frank K WilhelmAbstract:In this paper we derive an effective master Equation and quantum Trajectory Equation for multiple qubits in a single resonator and in the large resonator decay limit. We show that homodyne measurement of the resonator transmission is a weak measurement of the collective qubit inversion. As an example of this result, we focus on the case of two qubits and show how this measurement can be used to generate an entangled state from an initially separable state. This is realized without relying on an entangling Hamiltonian. We show that, for current experimental values of both the decoherence and measurement rates, this approach can be used to generate highly entangled states. This scheme takes advantage of the fact that one of the Bell states is decoherence-free under Purcell decay. PACS Nos.: 03.65.Yz, 42.50.Pq, 42.50.Lc, 74.50.r, 03.65.Ta Resume : Nous obtenons ici une Equation maitresse efficace et une Equation de trajectoire quantique pour plusieurs qubits dans un resonateur simple et dans la limite de desintegration d’un grand resonateur. Nous montrons que la mesure synchrone de la transmission du resonateur est une mesure faible de l’inversion collective des qubits. Comme exemple illustratif, nous focalisons sur le cas de deux qubits et montrons comment cette mesure peut etre utilisee pour generer un etat intrique a partir d’un etat initialement separe. Ceci se fait sans Hamiltonien d’intrication. Nous montrons que cette approche peut etre utilisee pour generer des etats hautement intriques, compte tenu des valeurs experimentales existantes des taux de decoherence et de mesure. L’approche tire profit du fait qu’un des etats de Bell est libre de decoherence sous desintegration de Purcell. [Traduit par la Redaction]

quantum Trajectory Equation for multiple qubits in circuit qed generating entanglement by measurement
arXiv: Mesoscale and Nanoscale Physics, 2008Co-Authors: Chantal L Hutchison, Jay M Gambetta, Alexandre Blais, Frank K WilhelmAbstract:In this paper we derive an effective master Equation and quantum Trajectory Equation for multiple qubits in a single resonator and in the large resonator decay limit. We show that homodyne measurement of the resonator transmission is a weak measurement of the collective qubit inversion. As an example of this result, we focus on the case of two qubits and show how this measurement can be used to generate an entangled state from an initially separable state. This is realized without relying on an entangling Hamiltonian. We show that, for {\em current} experimental values of both the decoherence and measurement rates, this approach can be used to generate highly entangled states. This scheme takes advantage of the fact that one of the Bell states is decoherence-free under Purcell decay.
