Quantum cryptography as a retrodiction problem.
We propose a quantum key distribution protocol based on a quantum retrodiction protocol, known as the Mean King problem. The protocol uses a two way quantum channel. We show security against coherent attacks in a transmission-error free scenario, even if Eve is allowed to attack both transmissions. This establishes a connection between retrodiction and key distribution.
متن کاملFrom retrodiction to Bayesian quantum imaging
We employ quantum retrodiction to develop a robust Bayesian algorithm for reconstructing the intensity values of an image from sparse photocount data, while also accounting for detector noise in the form of dark counts. This method yields not only a reconstructed image but also provides the full probability distribution function for the intensity at each pixel. We use simulated as well as real ...
متن کاملMultipartite quantum correlations in open quantum systems
In this paper, we present a measure of quantum correlation for a multipartite system, defined as the sum of the correlations for all possible partitions. Our measure can be defined for quantum discord (QD), geometric quantum discord or even for entanglement of formation (EOF). For tripartite pure states, we show that the multipartite measures for the QD and the EOF are equivalent, which allows ...
متن کاملTransitionless quantum driving in open quantum systems
We extend the concept of superadiabatic dynamics, or transitionless quantum driving, to quantum open systems whose evolution is governed by a master equation in the Lindblad form. We provide the general framework needed to determine the control strategy required to achieve superadiabaticity. We apply our formalism to two examples consisting of a two-level system coupled to environments with tim...
متن کاملComment on “ Time asymmetry in quantum mechanics: a retrodiction paradox”
It is shown that the “retrodiction paradox” recently introduced by Peres [Phys. Lett. A 194 ( 1994) 211 arises not because of the fallacy of the time-symmetric approach as he claimed, but due to an inappropriate use of retrodiction. In a recent Letter [ 11 Peres claimed that our timesymmetric approach to quantum theory [2,3], in which retrodictions and predictions are on an equal footing, leads...
