Noise refocusing in a five-blade neutron interferometer
Nsofini, Joachim; Sarenac, Dusan; Ghofrani, Kamyar; Huber, Michael G.; Arif, Muhammad; Cory, David G.; Pushin, Dimitry A. (AIP Publishing, 2017-08-07)We provide a quantum information description of a proposed five-blade neutron interferometer geometry and show that it is robust against low-frequency mechanical vibrations and dephasing due to the dynamical phase. The ... -
Quantum-information approach to dynamical diffraction theory
Nsofini, Joachim; Ghofrani, Kamyar; Sarenac, Dusan; Cory, David G.; Pushin, Dimitry A. (American Physical Society, 2016-12-08)We present a simplified model for dynamical diffraction of particles through a periodic thick perfect crystal based on repeated application of a coherent beam-splitting unitary at coarse-grained lattice sites. By demanding ...
