Two-qubit quantum probes for the temperature of an Ohmic environment
Francesca Gebbia, Claudia Benedetti, Fabio Benatti +3
We address a particular instance where open quantum systems may be used as quantum probes for an emergent property of a complex system, as the temperature of a thermal bath. The in…
Critical Quantum metrology with a finite-component quantum phase transition
Louis Garbe, Matteo Bina, Arne Keller +2
Physical systems close to a quantum phase transition exhibit a divergent susceptibility, suggesting that an arbitrarily-high precision may be achieved by exploiting quantum critica…
Quantum Probes for Ohmic Environments at Thermal Equilibrium
Fahimeh Salari Sehdaran, Matteo Bina, Claudia Benedetti +1
It is often the case that the environment of a quantum system may be described as a bath of oscillators with Ohmic density of states. In turn, the precise characterization of these…
Quantum state engineering by non-deterministic noiseless linear amplification
Hamza Adnane, Matteo Bina, Francesco Albarelli +2
We address quantum state engineering of single- and two-mode states by means of non-deterministic noiseless linear amplifiers (NLAs) acting on Gaussian states. In particular, we sh…
