Superconducting quantum interference devices based set-up for probing current noise and correlations in three-terminal devices.
We have implemented a new experimental set-up for precise measurements of current fluctuations in three-terminal devices. The system operates at very low temperatures (30 mK) and is equipped with three superconducting quantum interference devices (SQUIDs) as low noise current amplifiers. A SQUID input coil is connected to each terminal of a sample allowing the acquisition of time-dependent curr...
متن کاملEnergy dependence of current noise in superconducting/normal metal junctions.
Interference of electronic waves undergoing Andreev reflection in diffusive conductors determines the energy profile of the conductance on the scale of the Thouless energy. A similar dependence exists in the current noise, but its behavior is known only in a few limiting cases. We consider a metallic diffusive wire connected to a superconducting reservoir through an interface characterized by a...
متن کاملNoise correlations in three-terminal diffusive superconductor-normal-metal-superconductor nanostructures.
We present measurements of current noise and cross correlations in three-terminal superconductor-normal-metal-superconductor (S-N-S) nanostructures that are potential solid-state entanglers thanks to Andreev reflections at the N-S interfaces. The noise-correlation measurements spanned from the regime where electron-electron interactions are relevant to the regime of incoherent multiple Andreev ...
متن کاملMaximal positive cross-correlation of current noise from Andreev reflection
For more than a decade it has been accepted that the phenomena of quantum transport in mesoscopic systems are intimately connected with the fermionic nature of carriers, both electrons and holes. The simplest fingerprint of statistical interaction is the sub-Poissonian shot noise measured in the quantum point contact. I The electronic Hanbury BrownTwiss2 experiment performed in the quantum Hall...
متن کاملJosephson nonequilibrium phenomena under current injection in superconducting three-terminal stacked devices
Three-terminal superconducting tunnel devices offer a powerful tool to investigate nonequilibrium phenomena in superconductors. We study the role of the proximity effect in a Nb/Al bilayer forming the intermediate electrode of a stacked structure configuration. The spatial profile of the pair potential along the common electrode and the effective density of states near the detector tunnel barri...
