Non-Markovianity of a quantum emitter in front of a mirror
Tommaso Tufarelli, M. S. Kim, Francesco Ciccarello
We consider a quantum emitter ("atom") radiating in a one-dimensional (1D) photonic waveguide in the presence of a single mirror, resulting in a delay differential equation for the…
Detecting quantum non-Gaussianity of noisy Schrödinger cat states
Mattia L. Palma, Jimmy Stammers, Marco G. Genoni +4
Highly quantum non-linear interactions between different bosonic modes lead to the generation of quantum non-Gaussian states, i.e. states that cannot be written as mixtures of Gaus…
Quantum discord determines the interferometric power of quantum states
Davide Girolami, Alexandre M. Souza, Vittorio Giovannetti +6
Quantum metrology exploits quantum mechanical laws to improve the precision in estimating technologically relevant parameters such as phase, frequency, or magnetic fields. Probe st…
Coherently opening a high-Q cavity
Tommaso Tufarelli, Alessandro Ferraro, Alessio Serafini +2
We propose a general framework to effectively `open' a high-Q resonator, that is, to release the quantum state initially prepared in it in the form of a traveling electromagnetic w…
Affecting Non-Markovian behaviour by changing bath structures
V. Venkataraman, A. D. K. Plato, Tommaso Tufarelli +1
For many open quantum systems, a master equation approach employing the Markov approximation cannot reliably describe the dynamical behaviour. This is the case, for example, in a n…
Toward computability of trace distance discord
F. Ciccarello, T. Tufarelli, V. Giovannetti
It is known that a reliable geometric quantifier of discord-like correlations can be built by employing the so-called trace distance. This is used to measure how far the state unde…
