Sudden death and sudden birth of entanglement in common structured reservoirs
L. Mazzola, S. Maniscalco, J. Piilo +2
We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that, for certain classes of entangled states, entanglement sudden death occ…
Off-resonant entanglement generation in a lossy cavity
F. Francica, S. Maniscalco, J. Piilo +2
We provide an exact and complete characterization of the entanglement dynamics of two qubits coupled to a common structured reservoir at zero temperature. We derive the conditions…
Notes on Joint Measurability of Quantum Observables
Teiko Heinosaari, Daniel Reitzner, Peter Stano
For sharp quantum observables the following facts hold: (i) if we have a collection of sharp observables and each pair of them is jointly measurable, then they are jointly measurab…
Non-Markovian weak coupling limit of quantum Brownian motion
Sabrina Maniscalco, Jyrki Piilo, Kalle-Antti Suominen
We derive and solve analytically the non-Markovian master equation for harmonic quantum Brownian motion proving that, for weak system-reservoir couplings and high temperatures, it…
Optimal covariant measurements: the case of a compact symmetry group and phase observables
Claudio Carmeli, Teiko Heinosaari, Juha-Pekka Pellonpää +1
We study various optimality criteria for quantum observables. Observables are represented as covariant positive operator valued measures and we consider the case when the symmetry…
Stochastic jump processes for non-Markovian quantum dynamics
Heinz-Peter Breuer, Jyrki Piilo
It is shown that non-Markovian master equations for an open system which are local in time can be unravelled through a piecewise deterministic quantum jump process in its Hilbert s…
Pseudomodes as an effective description of memory: Non-Markovian dynamics of two-state systems in structured reservoirs
L. Mazzola, S. Maniscalco, J. Piilo +2
We investigate the non-Markovian dynamics of two-state systems in structured reservoirs. We establish a connection between two theoretical quantum approaches, the pseudomodes [B. M…
Semispectral measures as convolutions and their moment operators
Jukka Kiukas, Pekka Lahti, Kari Ylinen
The moment operators of a semispectral measure having the structure of the convolution of a positive measure and a semispectral measure are studied, with paying attention to the na…
Dynamical Casimir-Polder force between an atom and a conducting wall
R. Vasile, R. Passante
The time-dependent Casimir-Polder force arising during the time evolution of an initially bare two-level atom, interacting with the radiation field and placed near a perfectly cond…
Entanglement Trapping in Structured Environments
Bruno Bellomo, Rosario Lo Franco, Sabrina Maniscalco +1
The entanglement dynamics of two independent qubits each embedded in a structured environment under conditions of inhibition of spontaneous emission is analyzed, showing entangleme…
Measuring position and moment together
Paul Busch, Jukka Kiukas, Pekka Lahti
We describe an operational scheme for determining both the position and momentum distributions in a large class of quantum states, together with an experimental implementation.
Coexistence of qubit effects
Peter Stano, Daniel Reitzner, Teiko Heinosaari
We characterize all coexistent pairs of qubit effects. This gives an exhaustive description of all pairs of events allowed, in principle, to occur in a single qubit measurement. Th…
