Cooling many particles to very low temperatures
Almut Beige, Peter L. Knight, Giuseppe Vitiello
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently using a bichromatic interaction. The…
Speeding up gate operations through dissipation
Almut Beige, Hugo Cable, Carsten Marr +1
It is commonly believed that decoherence is the main obstacle to quantum information processing. In contrast to this, we show how decoherence in the form of dissipation can improve…
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…
Secure communication with a publicly known key
Almut Beige, Berthold-Georg Englert, Christian Kurtsiefer +1
We present a scheme for direct and confidential communication between Alice and Bob, where there is no need for establishing a shared secret key first, and where the key used by Al…
