Self-Sifting quantum key distribution
Saman Sarshar, Mostafa Annabestani
In this paper, we introduce a novel two-way quantum key distribution (QKD) protocol in which the sender (Alice) and receiver (Bob) employ one qubit of a maximally entangled Bell st…
Improving quantum walk metrology with split-step quantum walk
Majid Moradi, Mostafa Annabestani
A new estimation scheme based on the split-step quantum walk (SSQW) revealed that by just setting a single parameter, SSQW can potentially achieve quantum Crameŕ-Rao bound in multi…
Multi-parameter quantum metrology with discrete-time quantum walks
Mostafa Annabestani, Majid Hassani, Dario Tamascelli +1
We address multi-parameter quantum estimation for one-dimensional discrete-time quantum walks and its applications to quantum metrology. We use the quantum walker as a probe for un…
Asymptotic Behavior and Limiting Distribution of Quantum Walk on Cycles with General U(2) Coin by Reduced Characteristic Matrix Method
Majid Moradi, Mostafa Annabestani
We calculated reduced density characteristic matrix (RDCM) for quantum walk on cycles (QWC) to study asymptotic properties of the most general form of quantum walk on cycles with g…
Asymptotic reduced density matrix of discrete-time quantum walks
Mostafa Annabestani
In this article we show that for any quantum walker with \textit{m}-dimensional coin subspace, we have specific constant matrix where it completely de…
Möbius Quantum Walk
Majid Moradi, Mostafa Annabestani
By adding an extra Hilbert space to Hadamard Quantum Walk on Cycles (QWC), we presented a new type of QWCs called Möbius Quantum Walk (MQW). The new space configuration enables the…
Analytical expression for variance of homogeneous-position quantum walk with decoherent position
Mostafa Annabestani
We have derived an analytical expression for variance of homogeneous-position decoherent quantum walk (HPDQW) with general form of noise on its position, and have shown that, while…
Tunneling effects in a one-dimensional quantum walk
Mostafa Annabestani, Seyed Javad Akhtarshenas, Mohamad Reza Abolhassani
In this article we investigate the effects of shifting position decoherence, arisen from the tunneling effect in the experimental realization of the quantum walk, on the one-dimens…
Decoherence in one-dimensional Quantum Walk
Mostafa Annabestani, Seyed Javad Akhtarshenas, Mohamad Reza Abolhassani
In this paper we study decoherence in the quantum walk on the line. We generalize the method of decoherent coin quantum walk, introduced by Brun et al [Phys. Rev. A {\bf 67}, 32304…
Asymptotic entanglement in a two-dimensional quantum walk
Mostafa Annabestani, Mohammad Reza Abolhasani, Gonzalo Abal
The evolution operator of a discrete-time quantum walk involves a conditional shift in position space which entangles the coin and position degrees of freedom of the walker. After…
