   …of origin. Detection in the crystal plane reveals this information completely and destroys the polarization entanglement, so that a scheme using the near and far fields as conjugate spatial bases cannot support a…

6. Joint-measurement advantage and finite-time transitions in accelerated detector registers quant-ph · 14 Oct · 2 hits

   The Unruh response thermalizes accelerated detectors, but the entanglement remaining in a register does not by itself specify what distributed measurements can recover. We…
