Quantum Computation by Communication
T. P. Spiller, Kae Nemoto, Samuel L. Braunstein +3
We present a new approach to scalable quantum computing--a ``qubus computer''--which realises qubit measurement and quantum gates through interacting qubits with a quantum communic…
Some families of density matrices for which separability is easily tested
Samuel L. Braunstein, Sibasish Ghosh, Toufik Mansour +2
We reconsider density matrices of graphs as defined in [quant-ph/0406165]. The density matrix of a graph is the combinatorial laplacian of the graph normalized to have unit trace.…
Demonstration of quantum telecloning of optical coherent states
Satoshi Koike, Hiroki Takahashi, Hidehiro Yonezawa +4
Quantum cryptography promises in-principle secure communication between two parties via a quantum channel, with the ability to discover eavesdropping when it occurs. In 1999, a tel…
