Linear dynamical entropy and free-independence for quantized maps on the torus
Monika Pogorzelska, Robert Alicki
We study the relations between the averaged linear entropy production in periodically measured quantum systems and ergodic properties of their classical counterparts. Quantized lin…
Quantumness of Josephson junctions reexamined
Robert Alicki
There exists an increasing evidence supporting the picture of the Josephson junction (JJ) as a "macroscopic quantum system". On the other hand the interpretation of experimental da…
False qubits II. Entanglement of Josephson junctions
Robert Alicki
The recent experimental evidence for entangled states of two Josephson junction qubits is briefly discussed. It is argued that the interpretation of the experimental data strongly…
False qubits?: Polarization of light and Josephson junction
Robert Alicki
We compare two physical systems: polarization degrees of freedom of a macroscopic light beam and the Josephson junction (JJ) in the "charge qubit regime". The first system obviousl…
Can one build a quantum hard drive? A no-go theorem for storing quantum information in equilibrium systems
Robert Alicki, Michal Horodecki
We prove a no-go theorem for storing quantum information in equilibrium systems. Namely, quantum information cannot be stored in a system with time-independent Hamiltonian interact…
