High-efficiency Cooper pair splitting demonstrated by two-particle conductance resonance and positive noise cross-correlation

A Das, Y Ronen, M Heiblum, D Mahalu… - Nature …, 2012 - nature.com
Entanglement is at the heart of the Einstein-Podolsky-Rosen paradox, where the non-locality
is a necessary ingredient. Cooper pairs in superconductors can be split adiabatically, thus …

Near-unity Cooper pair splitting efficiency

J Schindele, A Baumgartner, C Schönenberger - Physical review letters, 2012 - APS
The two electrons of a Cooper pair in a conventional superconductor form a spin singlet and
therefore a maximally entangled state. Recently, it was demonstrated that the two particles …
