Discrimination of bosonic dephasing quantum channels

Samad Khabbazi Oskouei, Laleh Memarzadeh, Milajiguli Rexiti +1

We study the possibility of discriminating between two bosonic dephasing quantum channels. We show that unambiguous discrimination is not realizable. We then consider discriminatio…

On the effectiveness of Bayesian discrete feedback for quantum information reclaiming

Milajiguli Rexiti, Samad Khabbazi Oskouei, Stefano Mancini

We consider discrete time feedback aimed at reclaiming quantum information after a channel action. We compare Bayesian and Markovian strategies. We show that the former does not of…

Quantum reading of quantum information

Samad Khabbazi-Oskouei, Stefano Mancini, Milajiguli Rexiti

We extend the notion of quantum reading to the case where the information to be retrieved, which is encoded into a set of quantum channels, is of quantum nature. We use two qubit u…

Profitable entanglement for channel discrimination

Samad Khabbazi Oskouei, Stefano Mancini, Milajiguli Rexiti

We investigate the usefulness of side entanglement in discriminating between two generic qubit channels, {\ up to unitary pre- and post-processing,} and determine exact conditions…

Optimal input states for quantifying the performance of continuous-variable unidirectional and bidirectional teleportation

Hemant K. Mishra, Samad Khabbazi Oskouei, Mark M. Wilde

Continuous-variable (CV) teleportation is a foundational protocol in quantum information science. A number of experiments have been designed to simulate ideal teleportation under r…

Capacities of Gaussian Quantum Channels with Passive Environment Assistance

Samad Khabbazi Oskouei, Stefano Mancini, Andreas Winter

Passive environment assisted communication takes place via a quantum channel modeled as a unitary interaction between the information carrying system and an environment, where the…

Classical capacities of memoryless but not identical quantum channels

Samad Khabbazi Oskouei, Stefano Mancini

We study quantum channels that vary on time in a deterministic way, that is, they change in an independent but not identical way from one to another use. We derive coding theorems…

Union bound for quantum information processing

Samad Khabbazi Oskouei, Stefano Mancini, Mark M. Wilde

In this paper, we prove a quantum union bound that is relevant when performing a sequence of binary-outcome quantum measurements on a quantum state. The quantum union bound proved…

Quantum entropy and complexity

Fabio Benatti, Samad Khabbazi Oskouei, Ahmad Shafiei Deh Abad

We study the relations between the recently proposed machine-independent quantum complexity of P. Gacs~\cite{Gacs} and the entropy of classical and quantum systems. On one hand, by…

Algorithmic complexity of quantum capacity

Samad Khabbazi Oskouei, Stefano Mancini

Recently the theory of communication developed by Shannon has been extended to the quantum realm by exploiting the rules of quantum theory. This latter stems on complex vector spac…

Are there rings around Pluto?

J. J. Rawal, Bijan Nikouravan

Considering effects of tidal plus centrifugal stress acting on icy-rocks and the tensile strength thereof, icy-rocks being in the density range (1-2.4) g cm-3 which had come into e…
