A security proof of quantum cryptography based entirely on entanglement purification
Hans Aschauer, Hans J. Briegel
We give a proof that entanglement purification, even with noisy apparatus, is sufficient to disentangle an eavesdropper (Eve) from the communication channel. In the security regime…
The one-way quantum computer -- a non-network model of quantum computation
Robert Raussendorf, Daniel E. Browne, Hans J. Briegel
A one-way quantum computer works by only performing a sequence of one-qubit measurements on a particular entangled multi-qubit state, the cluster state. No non-local operations are…
Entanglement purification with noisy apparatus can be used to factor out an eavesdropper
Hans Aschauer, Hans J. Briegel
We give a proof that entanglement purification, even with noisy apparatus, is sufficient to disentangle an eavesdropper (Eve) from the communication channel. Our proof applies to a…
Computational model underlying the one-way quantum computer
Robert Raussendorf, Hans Briegel
In this paper we present the computational model underlying the one-way quantum computer which we introduced recently [Phys. Rev. Lett. 86, 5188 (2001)]. The one-way quantum comput…
