Trapping a particle of a quantum walk on the line
Antoni Wojcik, Tomasz Luczak, Pawel Kurzynski +3
We observe that changing a phase at a single point in a discrete quantum walk results in a rather surprising localization effect. For certain values of this phase change the possib…
Experimental undecidability of macroscopic quantumness
Pawel Kurzynski, Akihito Soeda, Ravishankar Ramanathan +3
Quantum mechanics marks a radical departure from the classical understanding of Nature, fostering an inherent randomness which forbids a deterministic description; yet the most fun…
Particle addition and subtraction as a test of bosonic quality
Pawel Kurzynski, Ravishankar Ramanathan, Akihito Soeda +2
We propose a test to measure the bosonic quality of particles with respect to physical operations of single-particle addition and subtraction. We apply our test to investigate boso…
Discrete Time Quantum Walk Approach to State Transfer
Pawel Kurzynski, Antoni Wojcik
We show that a quantum state transfer, previously studied as a continuous time process in networks of interacting spins, can be achieved within the model of discrete time quantum w…
Criteria for two distinguishable fermions to behave like a boson
Ravishankar Ramanathan, Pawel Kurzynski, Tan Kok Chuan +2
We study the necessary conditions for bosons composed of two distinguishable fermions to exhibit bosonic-like behaviour. We base our analysis on tools of quantum information theory…
