Mutually equibiased bases
Seyed Javad Akhtarshenas, Saman Karimi, Mahdi Salehi
In the framework of mutually unbiased bases (MUBs), a measurement in one basis gives \emph{no information} about the outcomes of measurements in another basis. Here, we relax the n…
Quantum Zeno Dynamics of Two Interacting Particles
Varqa Abyaneh, Parsa Ghorbani
According to quantum Zeno dynamics (QZD), the evolution of a quantum system can be restricted to a subspace of its Hilbert space by frequent measurements. A crucial question in QZD…
Measurement sharpness and disturbance tradeoff
Nayere Saberian, Seyed Javad Akhtarshenas, Fereshte Shahbeigi
Obtaining information from a quantum system through a measurement typically disturbs its state. The postmeasurement states for a given measurement, however, are not unique and high…
Instantaneous measurement can isolate the information
Iman Sargolzahi
Consider a one-dimensional spin chain, from spin 1 to spin N, such that each spin interacts with its nearest neighbors. Performing a local operation (measurement) on spin N, we exp…
Optimal quantum speed for mixed states
Ashraf Naderzadeh-ostad, Seyed Javad Akhtarshenas
The question of how fast a quantum state can evolve is considered. Using the definition of squared speed based on the Euclidean distance given in [Phys. Rev. Research, {\bf 2}, 033…
Accelerated Gaussian quantum state transfer between two remote mechanical resonators
M. Rezaei, K. Javidan, M. Abdi
The main challenge in deterministic quantum state transfer between remote mechanical resonators is the local decoherence and the transmission losses in the communication channel. I…
Mutually unbiased measurements with arbitrary purity
Mahdi Salehi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei +1
Mutually unbiased measurements are a generalization of mutually unbiased bases in which the measurement operators need not to be rank one projectors. In a -dimension space, the…
Optimized Quantum Circuit Partitioning
Omid Daei, Keivan Navi, Mariam Zomorodi-Moghadam
The main objective of this paper is to improve the communication costs in distributed quantum circuits. To this end, we present a method for generating distributed quantum circuits…
Log-Convex set of Lindblad semigroups acting on -level system
Fereshte Shahbeigi, David Amaro-Alcalá, Zbigniew Puchała +1
We analyze the set of mixed unitary channels represented in the Weyl basis and accessible by a Lindblad semigroup acting on an -level quantum system. General nece…
Synchronization along quantum trajectories
Najmeh Es'haqi-Sani, Gonzalo Manzano, Roberta Zambrini +1
We employ a quantum trajectory approach to characterize synchronization and phase-locking between open quantum systems in nonequilibrium steady states. We exemplify our proposal fo…
Non-Gaussian macroscopic entanglement of motion in a hybrid electromechanical device
Najmeh Es'haqi-Sani, Mehdi Khazaei Nezhad, Mehdi Abdi
We propose a scheme for entangling the motion of two massive objects in a hybrid electromechanical architecture. The entanglement is generated due to the interaction of two mechani…
Quantumness of quantum channels
Fereshte Shahbeigi, Seyed Javad Akhtarshenas
Quantum coherence is a fundamental aspect of quantum physics and plays a central role in quantum information science. This essential property of the quantum states could be fragile…
Quantum Fisher information matrix for unitary processes: closed relation for
Mohammad Javad Shemshadi, Seyed Javad Akhtarshenas
Quantum Fisher information plays a central role in the field of quantum metrology. In this paper we study the problem of quantum Fisher information of unitary processes. Associated…
Measuring quantum discord using the most distinguishable steered states
Vahid Nassajpour, Seyed Javad Akhtarshenas
Any two-qubit state can be represented, geometrically, as an ellipsoid with a certain size and a center located within the Bloch sphere of one of the qubits. Points of this ellipso…
Parametrization of quantum states and the quantum state discrimination problem
Seyed Arash Ghoreishi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
A discrimination problem consists of linearly independent pure quantum states and the corresponding occurrence probabilities . To any such problem…
Reexamination of strong subadditivity: A quantum-correlation approach
Razieh Taghiabadi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
The strong subadditivity inequality of von Neumann entropy relates the entropy of subsystems of a tripartite state to that of the composite system. Here, we define $\bold…
Comparison of quantum discord and fully entangled fraction of two classes of states
Javad Behdani, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
The quantumness of a generic state is the resource of many applications in quantum information theory and it is interesting to survey the measures which are able to detect its trac…
Two-qubit universal and state-dependent quantum cloning machine and quantum correlation broadcasting
Azam Kheirollahi, Hamidreza Mohammadi, Seyed Javad Akhtarshenasc
Due to the axioms of quantum mechanics, perfect cloning of an unknown quantum state is impossible. But since imperfect cloning is still possible, a question arises: "Is there an op…
Revealing quantum correlation by negativity of the Wigner function
Razieh Taghiabadi, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
We analyze two two-mode continuous variable separable states with the same marginal states. We adopt the definition of classicality in the form of well-defined positive Wigner func…
Quantifying Nonclassicality of Correlations based on the Concept of Nondisruptive Local State Identification
Azam Kheirollahi, Seyed Javad Akhtarshenas, Hamidreza Mohammadi
A bipartite state is classical with respect to party if and only if party can perform nondisruptive local state identification (NDLID) by a projective measurement. Motivate…

Javad Behdani, Seyed Javad Akhtarshenas, Mohsen Sarbishaei
Quantum discord as a measure of the quantum correlations cannot be easily computed for most of density operators. In this paper, we present a measure of the total quantum correlati…
