Sequential Quantum Cloning
Y. Delgado, L. Lamata, J. Leon +2
Not all unitary operations upon a set of qubits can be implemented by sequential interactions between each qubit and an ancillary system. We analyze the specific case of sequential…
Experimental Observation of Four-Photon Entangled Dicke State with High Fidelity
Nikolai Kiesel, Christian Schmid, Geza Toth +2
We present the experimental observation of the symmetric four-photon entangled Dicke state with two excitations . A simple experimental set-up allowed quantum state…
Crossover from weak to strong coupling regime in dispersive circuit QED
I. Serban, E. Solano, F. K. Wilhelm
We study the decoherence of a superconducting qubit due to the dispersive coupling to a damped harmonic oscillator. We go beyond the weak qubit-oscillator coupling, which we associ…
Tavis-Cummings model and collective multi-qubit entanglement in trapped ions
A. Retzker, E. Solano, B. Reznik
We present a method of generating collective multi-qubit entanglement via global addressing of an ion chain following the guidelines of the Tavis-Cummings model, where several qubi…
