Selfcomplementary quantum channels
Marek Smaczynski, Wojciech Roga, Karol Zyczkowski
Selfcomplementary quantum channels are characterized by such an interaction between the principal quantum system and the environment that leads to the same output states of both in…
Extremal spacings between eigenphases of random unitary matrices and their tensor products
Marek Smaczynski, Tomasz Tkocz, Marek Kus +1
Extremal spacings between eigenvalues of random unitary matrices of size N pertaining to circular ensembles are investigated. Explicit probability distributions for the minimal spa…
Tensor Products of Random Unitary Matrices
Tomasz Tkocz, Marek Smaczynski, Marek Kus +2
Tensor products of M random unitary matrices of size N from the circular unitary ensemble are investigated. We show that the spectral statistics of the tensor product of random mat…
Composition of quantum operations and products of random matrices
Wojciech Roga, Marek Smaczynski, Karol Zyczkowski
Spectral properties of evolution operators corresponding to random maps and quantized chaotic systems strongly interacting with an environment can be described by the ensemble of n…
Universality of spectra for interacting quantum chaotic systems
Wojciech Bruzda, Marek Smaczynski, Valerio Cappellini +2
We analyze a model quantum dynamical system subjected to periodic interaction with an environment, which can describe quantum measurements. Under the condition of strong classical…
