Electrically addressing a single self-assembled quantum dot
D. J. P. Ellis, A. J. Bennett, P. Atkinson +2
We report on the use of an aperture in an aluminum oxide layer to restrict current injection into a single self-assembled InAs quantum dot, from an ensemble of such dots within a l…
Pooling quantum states obtained by indirect measurements
Robert W. Spekkens, H. M. Wiseman
We consider the pooling of quantum states when Alice and Bob both have one part of a tripartite system and, on the basis of measurements on their respective parts, each infers a qu…
On the impossibility of extracting classical randomness using a quantum computer
Yevgeniy Dodis, Renato Renner
In this work we initiate the question of whether quantum devices can provide us with an almost perfect source of classical randomness, and more generally, suffice for classical cry…
Asymptotic entanglement manipulation of bipartite pure states
Garry Bowen, Nilanjana Datta
Entanglement of pure states of bipartite quantum systems has been shown to have a unique measure in terms of the von Neumann entropy of the reduced states of either of its subsyste…
Coding Theorem for a Class of Quantum Channels with Long-Term Memory
Nilanjana Datta, Tony Dorlas
In this paper we consider the transmission of classical information through a class of quantum channels with long-term memory, which are given by convex combinations of product cha…
A Model for an Irreversible Bias Current in the Superconducting Qubit Measurement Process
G. D. Hutchinson, C. A. Holmes, T. M. Stace +5
The superconducting charge-phase `Quantronium' qubit is considered in order to develop a model for the measurement process used in the experiment of Vion et. al. [Science 296 886 (…
