Deterministic carving of quantum states with Grover's algorithm
Omar Nagib, M. Saffman, K. Mølmer
We show that iteration of a few ( ) unitary steps of Grover's algorithm suffices to perfectly prepare a Dicke state of atoms in a cavity. We also show that a few…

Efficient preparation of entangled states in cavity QED with Grover's algorithm
Omar Nagib, M. Saffman, K. Mølmer
We propose to employ the amplification mechanism of Grover's search algorithm to efficiently prepare entangled states of an ensemble of qubits. The conditional change of sign emplo…

Robust atom-photon gate for quantum information processing
Omar Nagib, P. Huft, A. Safari +1
We propose a scheme for two-qubit gates between a flying photon and an atom in a cavity. The atom-photon gate setup consists of a cavity and a Mach-Zehnder interferometer with doub…
