Dual-path methods for propagating quantum microwaves
(IOP Publishing, 2014-01)
We study quantum state tomography, entanglement detection and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use of the following key elements: propagation ...
Secure quantum remote state preparation of squeezed microwave states
(Nature Publishing, 2019-06-13)
Quantum communication protocols based on nonclassical correlations can be more efficient than known classical methods and offer intrinsic security over direct state transfer. In particular, remote state preparation aims ...
Finite-time quantum entanglement in propagating squeezed microwaves
(Nature Publishing, 2018-04-23)
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of non-commuting observables between two subsystems. At the same time, these subsystems themselves may contain no quantum ...
