Two-particle Hadamard walk on dynamically percolated line and circle
M. Paryzkova, M. Stefanak, J. Novotny +2
Asymptotic dynamics of a Hadamard walk of two non-interacting quantum particles on a dynamically percolated finite line or a circle is investigated. We construct a basis of the att…
Testing quantum computers with the protocol of quantum state matching
Adrian Ortega, Orsolya Kálmán, Tamás Kiss
The presence of noise in quantum computers hinders their effective operation. Even though quantum error correction can theoretically remedy this problem, its practical realization…
Complete classification of trapping coins for quantum walks on the 2D square lattice
Bálint Kollár, András Gilyén, Iva Tkáčová +3
One of the unique features of discrete-time quantum walks is called trapping, meaning the inability of the quantum walker to completely escape from its initial position, albeit the…
Experimental orthogonalization of highly overlapping quantum states with single photons
Gaoyan Zhu, Orsolya Kalman, Kunkun Wang +6
We experimentally realize a nonlinear quantum protocol on single-photon qubits with linear optical elements and appropriate measurements. The quantum nonlinearity is induced by pos…
Phase Transition in Iterated Quantum Protocols for Noisy Inputs
Martin Malachov, Igor Jex, Orsolya Kálmán +1
Quantum information processing exploits all the features quantum mechanics offers. Among them there is the possibility to induce nonlinear maps on a quantum system by involving two…
Quantum state identification of qutrits via a nonlinear protocol
P. V. Pyshkin, A. Gábris, O. Kálmán +2
We propose a probabilistic quantum protocol to realize a nonlinear transformation of qutrit states, which by iterative applications on ensembles can be used to distinguish two type…
