Simulation of quantum dynamics with quantum optical systems
E. Jané, G. Vidal, W. Dür +2
We propose the use of quantum optical systems to perform universal simulation of quantum dynamics. Two specific implementations that require present technology are put forward for…
Equivalence classes of non-local unitary operations
W. Dür, J. I. Cirac
We study when a multipartite non--local unitary operation can deterministically or probabilistically simulate another one when local operations of a certain kind -in some cases inc…
Quantum repeaters for communication
H. -J. Briegel, W. Dür, J. I. Cirac +1
In quantum communication via noisy channels, the error probability scales exponentially with the length of the channel. We present a scheme of a quantum repeater that overcomes thi…
Quantum communication and the creation of maximally entangled pairs of atoms over a noisy channel
H. -J. Briegel, W. Dür, S. J. van Enk +2
We show how to create maximally entangled EPR pairs between spatially distant atoms, each of them inside a high-Q optical cavity, by sending photons through a general, noisy channe…
