Dynamics of Entanglement and `Attractor' states in The Tavis-Cummings Model

Autor: Jarvis, C. E. A., Rodrigues, D. A., Györffy, B. L., Spiller, T. P., Short, A. J., Annett, J. F.

We study the time evolution of $N_q$ two-level atoms (or qubits) interacting with a single mode of the quantised radiation field. In the case of two qubits, we show that for a set of initial conditions the reduced density matrix of the atomic system

Collapse and Revival of `Schr\'odinger Cat' States

Autor: Jarvis, C. E. A., Rodrigues, D. A., Györffy, B. L., Spiller, T. P., Short, A. J., Annett, J. F.

We study the dynamics of the Jaynes-Cummings Model for an array of $N_q$ two level systems (or qubits) interacting with a quantized single mode electromagnetic cavity (or quantum bus). For an initial cavity coherent state $| \alpha >$ and the qubit s

Collapse and Revival of Entanglement between Qubits Interacting via a Quantum Bus

Autor: Jarvis, C. E. A., Rodrigues, D. A., Györffy, B. L., Spiller, T. P., Short, A. J., Annett, J. F.

We study the dynamics of the Jaynes-Cummings Model for two level systems (or qubits) interacting with a quantized single mode electromagnetic cavity (or `quantum bus'). We show that there is a time in between the collapse and revival of Rabi oscillat

Entanglement of superconducting charge qubits by homodyne measurement

Autor: Rodrigues, D. A., Jarvis, C. E. A., Györffy, B. L., Spiller, T. P., Annett, J. F.

Publikováno v: J. Phys.: Condens. Matter, 20, (2008), 075211

We present a scheme by which projective homodyne measurement of a microwave resonator can be used to generate entanglement between two superconducting charge qubits coupled to this resonator. The non-interacting qubits are initialised in a product of
