We discuss the detection of quantum fluctuations in the light of the relationship between time-dependent correlators and measurable properties [L. Van Hove, Phys. Rev 95, 249 (1954)]. Considering the interaction between the fluctuating electron syste

The Return Probability ofNStrongly Repelling Classical Diffusing Particles in Quasi-1D, an Exact Solution

Autor: U. Gavish, Y. Imry

Publikováno v: Annals of Physics. 268:359-402

N classical particles diffuse inside the one-dimensional interval [0, L ]. There are reflecting walls at the edges of this interval. The diffusion constant of each particle is assumed independent of its energy and position. The particles interact thr

The spectral theory of quantum graphs is related via an exact trace formula with the spectrum of the lengths of periodic orbits (cycles) on the graphs. The latter is a degenerate spectrum, and understanding its structure (i.e.,finding out how many di

High-fidelity transfer of an arbitrary quantum state between harmonic oscillators

Autor: U. Gavish, K. Jahne, Bernard Yurke

Publikováno v: Physical Review A. 75

It is shown that by switching a specific time-dependent interaction between a harmonic oscillator and a transmission line (a waveguide, an optical fiber, etc.) the quantum state of the oscillator can be transferred into that of another oscillator cou

Quantum Noise Minimization in Transistor Amplifiers

Autor: U. Gavish, Yoseph Imry, Bernard Yurke

Publikováno v: Physical Review Letters. 96

General quantum restrictions on the noise performance of linear transistor amplifiers are used to identify the region in parameter space where the quantum-limited performance is achievable and to construct a practical procedure for approaching it exp

Noise Minimization in Quantum Transistors

Autor: Bernard Yurke, Yoseph Imry, U. Gavish

Publikováno v: AIP Conference Proceedings.

We present limits on the minimal noise produced in transistor‐type linear amplifiers and a practical procedure for obtaining these limits. The validity of the procedure is verified for a signal which is produced by a set of LC circuits and amplifie

Matterwave localization in disordered cold atom lattices

Publikováno v: Physical Review Letters

Physical Review Letters, American Physical Society, 2005, 95, pp.020401

We propose to observe Anderson localization of ultracold atoms in the presence of a random potential made of atoms of another species and trapped at the nodes of an optical lattice, with a filling factor less than unity. Such systems enable a nearly

Generalized constraints on quantum amplification

Autor: U. Gavish, Yoseph Imry, Bernard Yurke

We derive quantum constraints on the minimal amount of noise added in linear amplification involving input or output signals whose component operators do not necessarily have c-number commutators, as is the case for fermion currents. This is a genera
