Separability of very noisy mixed states and implications for NMR quantum computing
S. L. Braunstein, C. M. Caves, R. Jozsa +3
We give a constructive proof that all mixed states of N qubits in a sufficiently small neighborhood of the maximally mixed state are separable. The construction provides an explici…
Quantum teleportation with squeezed vacuum states
G. J. Milburn, S. L. Braunstein
We show how the partial entanglement inherent in a two mode squeezed vacuum state admits two different teleportation protocols. These two protocols refer to the different kinds of…
Quantum computation over continuous variables
Seth Lloyd, Samuel L. Braunstein
This paper provides necessary and sufficient conditions for constructing a universal quantum computer over continuous variables. As an example, it is shown how a universal quantum…
A posteriori teleportation
Samuel L. Braunstein, H. J. Kimble
The article by Bouwmeester et al. on experimental quantum teleportation constitutes an important advance in the burgeoning field of quantum information. The experiment was motivate…
A quantum analog of Huffman coding
Samuel L. Braunstein, Christopher A. Fuchs, Daniel Gottesman +1
We analyze a generalization of Huffman coding to the quantum case. In particular, we notice various difficulties in using instantaneous codes for quantum communication. Nevertheles…
