Decoherence-free dynamical and geometrical entangling phase gates
Jiannis K. Pachos, Almut Beige
It is shown that entangling two-qubit phase gates for quantum computation with atoms inside a resonant optical cavity can be generated via common laser addressing, essentially, wit…
Photon polarisation entanglement from distant dipole sources
Yuan Liang Lim, Almut Beige
It is commonly believed that photon polarisation entanglement can only be obtained via pair creation within the same source or via postselective measurements on photons that overla…
Quantum computing using dissipation (proceedings)
Almut Beige
The principal obstacle to quantum information processing with many qubits is decoherence. One source of decoherence is spontaneous emission which causes loss of energy and informat…
Entangled state preparation via dissipation-assisted adiabatic passages
Carsten Marr, Almut Beige, Gerhard Rempe
The main obstacle for coherent control of open quantum systems is decoherence due to different dissipation channels and the inability to precisely control experimental parameters.…
Ion-trap quantum computing in the presence of cooling
Almut Beige
This paper discusses ways to implement two-qubit gate operations for quantum computing with cold trapped ions within one step. The proposed scheme is widely robust against paramete…
Dissipation-assisted quantum computation in atom-cavity systems
Almut Beige, Hugo Cable, Peter L. Knight
The principal obstacle to quantum information processing with many qubits is decoherence. One source of decoherence is spontaneous emission which causes loss of energy and informat…
