Query: Entangling electrons by splitting Cooper pairs: Two-particle conductance
  resonance and time coincidence measurements   Entanglement, being at the heart of the Einstein-Podolsky-Rosen (EPR)
paradox, is a necessary ingredient in processing quantum information. Cooper
pairs in superconductors - being composites of two fully entangled electrons -
can be split adiabatically, thus forming entangled electrons. We fabricated
such electron splitter by contacting an aluminum superconductor strip at the
center of a suspended InAs nanowire; terminated at both ends with two normal
metallic drains. Intercepting each half of the nanowire by gate - induced
Coulomb blockaded quantum dot strongly impeded the flow of Cooper pairs due to
large charging energy, while still permitting passage of single electrons.
Here, we provide conclusive evidence of extremely high efficiency Cooper pairs
splitting via observing positive average (conductance) and time (shot noise)
correlations of the split electrons in the two opposite drains of the nanowire.
Moreover, The actual charge of the injected quasiparticles was verified by shot
noise measurements.
