Quantum survival in hybrid pursuit dynamics - a lion chasing a lamb problem
P. Held, İ. Yalçınkaya, F. Pegoraro +10
Measurement and classical randomness usually degrade coherence; controlling where and when a subsystem is monitored can instead make them a tunable resource. We introduce a photoni…
Recurrence in discrete-time quantum stochastic walks
Martin Stefanak, Vaclav Potocek, Iskender Yalcinkaya +2
Interplay between quantum interference and classical randomness can enhance performance of various quantum information tasks. In the present paper we analyze recurrence phenomena i…
Disorder-free localization in quantum walks
B. Danacı, İ. Yalçınkaya, B. Çakmak +3
The phenomenon of localization usually happens due to the existence of disorder in a medium. Nevertheless, certain quantum systems allow dynamical localization solely due to the na…
Synchronization and Non-Markovianity in open quantum systems
Göktuğ Karpat, İskender Yalçınkaya, Barış Çakmak +2
Detuned systems can spontaneously achieve a synchronous dynamics and display robust quantum correlations in different local and global dissipation regimes. Beyond the Markovian lim…
Quantum synchronization of few-body systems under collective dissipation
G. Karpat, İ. Yalçınkaya, B. Çakmak
We explore the environment-induced synchronization phenomenon in two-level systems in contact with a thermal dissipative environment. We first discuss the conditions under which sy…
Quantum synchronization in a collision model
G. Karpat, İ. Yalçınkaya, B. Çakmak
We reveal the emergence of environment-induced spontaneous synchronization between two spin-1/2 quantum objects in a collision model setting. In particular, we determine the condit…
Non-markovianity and bound states in quantum walks with a phase impurity
B. Danacı, G. Karpat, İ. Yalçınkaya +1
We study a quantum walker on a one-dimensional lattice with a single defect site characterized by a phase. The spread and localization of discrete-time quantum walks starting at th…
Continuous dynamical decoupling and decoherence-free subspaces for qubits with tunable interaction
İ. Yalçınkaya, B. Çakmak, G. Karpat +1
Protecting quantum states from the decohering effects of the environment is of great importance for the development of quantum computation devices and quantum simulators. Here, we…
Optimization and experimental realization of the quantum permutation algorithm
İ. Yalçınkaya, Z. Gedik
The quantum permutation algorithm provides computational speed-up over classical algorithms in determining the parity of a given cyclic permutation. For its -qubit implementatio…
Coherent transport over an explosive percolation lattice
İ. Yalçınkaya, Z. Gedik
We investigate coherent transport over a finite square lattice in which the growth of bond percolation clusters are subjected to an Achlioptas type selection process, i.e., whether…
Two-dimensional quantum walk under artificial magnetic field
İ. Yalçınkaya, Z. Gedik
We introduce the Peierls substitution to a two-dimensional discrete-time quantum walk on a square lattice to examine the spreading dynamics and the coin-position entanglement in th…
Qubit state transfer via discrete-time quantum walks
İ. Yalçınkaya, Z. Gedik
We propose a scheme for perfect transfer of an unknown qubit state via the discrete-time quantum walk on a line or a circle. For this purpose, we introduce an additional coin opera…
