A proof for the informational completeness of the rotated quadrature observables
J. Kiukas, P. Lahti, J. -P. Pellonpaa
We give a new mathematically rigorous proof for the fact that, when is a dense subset of , the rotated quadrature operators , , of a single mode electromag…
Discrimination of quantum observables using limited resources
Mario Ziman, Teiko Heinosaari
We address the problem of unambiguous discrimination and identification among quantum observables. We set a general framework and investigate in details the case of qubit observabl…
Protecting entanglement via the quantum Zeno effect
Sabrina Maniscalco, Francesco Francica, Rosa L. Zaffino +2
We study the exact entanglement dynamics of two atoms in a lossy resonator. Besides discussing the steady-state entanglement, we show that in the strong coupling regime the system-…
Population trapping due to cavity losses
M. Scala, B. Militello, A. Messina +3
In population trapping the occupation of a decaying quantum level keeps a constant non-zero value. We show that an atom-cavity system interacting with an environment characterized…
Cavity losses for the dissipative Jaynes-Cummings Hamiltonian beyond Rotating Wave Approximation
M. Scala, B. Militello, A. Messina +3
A microscopic derivation of the master equation for the Jaynes-Cummings model with cavity losses is given, taking into account the terms in the dissipator which vary with frequenci…
A note on the measurement of phase space observables with an eight-port homodyne detector
J. Kiukas, P. Lahti
It is well known that the Husimi Q-function of the signal field can actually be measured by the eight-port homodyne detection technique, provided that the reference beam (used for…
On the moment limit of quantum observables, with an application to the balanced homodyne detection
J. Kiukas, P. Lahti
We consider the moment operators of the observable (i.e. a semispectral measure or POM) associated with the balanced homodyne detection statistics, with paying attention to the cor…
Non-Markovian quantum jumps
J. Piilo, S. Maniscalco, K. Harkonen +1
Open quantum systems that interact with structured reservoirs exhibit non-Markovian dynamics. We present a quantum jump method for treating the dynamics of such systems. This appro…
Approximate joint measurements of qubit observables
Paul Busch, Teiko Heinosaari
Joint measurements of qubit observables have recently been studied in conjunction with quantum information processing tasks such as cloning. Considerations of such joint measuremen…
Entanglement oscillations in non-Markovian quantum channels
Sabrina Maniscalco, Stefano Olivares, Matteo G. A. Paris
We study the non-Markovian dynamics of a two-mode bosonic system interacting with two uncorrelated thermal bosonic reservoirs. We present the solution to the exact microscopic Mast…
