Non-Markovianity of a quantum emitter in front of a mirror (2014)
Journal Article
Tufarelli, T., Kim, M., & Ciccarello, F. (2014). Non-Markovianity of a quantum emitter in front of a mirror. Physical Review A, 90(1), doi:10.1103/PhysRevA.90.012113

We consider a quantum emitter (“atom”) radiating in a one-dimensional photonic waveguide in the presence of a single mirror, resulting in a delay differential equation for the atomic amplitude. We carry out a systematic analysis of the non-Markovian... Read More about Non-Markovianity of a quantum emitter in front of a mirror.

Quantum discord determines the interferometric power of quantum states (2014)
Journal Article
Girolami, D., Souza, A. M., Giovannetti, V., Tufarelli, T., Filgueiras, J. G., Sarthour, R. S., …Adesso, G. (2014). Quantum discord determines the interferometric power of quantum states. Physical Review Letters, 112(21), https://doi.org/10.1103/PhysRevLett.112.210401

Quantum metrology exploits quantum mechanical laws to improve the precision in estimating technologically relevant parameters such as phase, frequency, or magnetic fields. Probe states are usually tailored to the particular dynamics whose parameters... Read More about Quantum discord determines the interferometric power of quantum states.

Coherently opening a high-Q cavity (2014)
Journal Article
Tufarelli, T., Serafini, A., Ferraro, A., Kim, M. S., & Bose, S. (2014). Coherently opening a high-Q cavity. Physical Review Letters, 112(13), doi:10.1103/PhysRevLett.112.133605

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 wave. This is achieved by employing a mediating mode that scatters cohe... Read More about Coherently opening a high-Q cavity.

Toward computability of trace distance discord (2014)
Journal Article
Ciccarello, F., Tufarelli, T., & Giovannetti, V. (2014). Toward computability of trace distance discord. New Journal of Physics, 16, doi:10.1088/1367-2630/16/1/013038

It is known that a reliable geometric quantifier of discord-like correlations can be built by employing the so-called trace distance, which is used to measure how far the state under investigation is from the closest 'classical-quantum' state. To dat... Read More about Toward computability of trace distance discord.
