The statistical error in any estimation can be reduced by repeating the measurement and averaging the results. The central limit theorem implies that the reduction is proportional to the square root… Expand

Architectures for a quantum random access memory

- V. Giovannetti, S. Lloyd, L. Maccone
- Physics

A random access memory, or RAM, is a device that, when interrogated, returns the content of a memory location in a memory array. A quantum RAM, or qRAM, allows one to access superpositions of memory… Expand

Classical capacity of the lossy bosonic channel: the exact solution.

- V. Giovannetti, S. Guha, S. Lloyd, L. Maccone, J. Shapiro, H. Yuen
- Physics, Medicine
- Physical review letters
- 1 August 2003

The classical capacity of the lossy bosonic channel is calculated exactly. It is shown that its Holevo information is not superadditive, and that a coherent-state encoding achieves capacity. The… Expand

Ultimate classical communication rates of quantum optical channels

- Physics
- 1 October 2014

The Gaussian minimum entropy conjecture—a long-standing open question—has now been proved for single-mode phase-insensitive bosonic Gaussian channels. This establishes the ultimate achievable bit… Expand

Characterizing the entanglement of bipartite quantum systems

- V. Giovannetti, S. Mancini, D. Vitali, P. Tombesi
- Physics
- 22 October 2002

We derive a separability criterion for bipartite quantum systems which generalizes the already known criteria. It is based on observables having generic commutation relations. We then discuss in… Expand
