Degeneracies in the length spectra of metric graphs
U. Gavish, U. Smilansky
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 s…
High fidelity transfer of an arbitrary quantum state between harmonic oscillators
K. Jahne, B. Yurke, U. Gavish
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…
Quantum noise minimization in transistor amplifiers
U. Gavish, B. Yurke, Y. Imry
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 ac…
Matterwave localization in disordered cold atom lattices
U. Gavish, Y. Castin
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…
Heisenberg constraints on mesoscopic and molecular amplifiers
U. Gavish, B. Yurke, Y. Imry
Heisenberg uncertainty relations for current components impose constraints on the performance of linear amplifiers. Here we derive such constraints for amplifiers in which the inpu…
Generalized constraints on quantum amplification
U. Gavish, B. Yurke, Y. Imry
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-num…
