A universal quantum estimator
INT J QUANTUM INF 3 (2005) 123-132
Abstract:
Almost all computational tasks in the modem computer can be designed from basic building blocks. These building blocks provide a powerful and efficient language for describing algorithms. In quantum computers, the basic building blocks are the quantum gates. In this tutorial, we will look at quantum gates that act on one and two qubits and briefly discuss how these gates can be used in quantum networks.A UNIVERSAL QUANTUM ESTIMATOR

Surface-acoustic-wave single-electron interferometry
Physical Review B Condensed Matter and Materials Physics 72:8 (2005)
Abstract:
We propose an experiment to observe interference of a single electron as it is transported along two parallel quasi-one-dimensional channels trapped in a single minimum of a traveling periodic electric field. The experimental device is a modification of the surface-acoustic-wave-based quantum processor. Interference is achieved by creating a superposition of spatial wave functions between the two channels and inducing a relative phase shift via either a transverse electric field or a magnetic field. The interference can be used to estimate the decoherence time of an electron in this type of solid-state device. 漏 2005 The American Physical Society.Quantum Physics from A to Z
