Conditional generation of optical Schrödinger cat states
P. Adam, T. Kiss, Z. Darázs +1
Given a source of two coherent state superpositions with small separation in a traveling wave optical setting, we show that by interference and balanced homodyne measurement it is…
Generalized Kac's Lemma for Recurrence Time in Iterated Open Quantum Systems
P. Sinkovicz, T. Kiss, J. K. Asbóth
We consider recurrence to the initial state after repeated actions of a quantum channel. After each iteration a projective measurement is applied to check recurrence. The correspon…
Quantized recurrence time in iterated open quantum dynamics
P. Sinkovicz, Z. Kurucz, T. Kiss +1
The expected return time to the original state is a key concept characterizing systems obeying both classical or quantum dynamics. We consider iterated open quantum dynamical syste…
Percolation induced effects in 2D coined quantum walks: analytic asymptotic solutions
Bálint Kollár, Jaroslav Novotný, Tamás Kiss +1
Quantum walks on graphs can model physical processes and serve as efficient tools in quantum information theory. Once we admit random variations in the connectivity of the underlyi…
Quantum Walk with Jumps
H. Lavička, V. Potoček, T. Kiss +2
We analyze a special class of 1-D quantum walks (QWs) realized using optical multi-ports. We assume non-perfect multi-ports showing errors in the connectivity, i.e. with a small pr…
