Hybrid Analog Teleportation-Direct Transmission in Noisy Bosonic Channels
Uesli Alushi, Simone Felicetti, Roberto Di Candia
Quantum teleportation uses a shared entangled resource, local operations, and a digitally error-corrected classical channel to transfer quantum states between distant parties. We i…
Dynamical entanglement percolation with spatially correlated disorder
Lorenzo Cirigliano, Valentina Brosco, Claudio Castellano +3
The distribution of entanglement between the nodes of a quantum network plays a fundamental role in quantum information applications. In this work, we investigate the dynamics of a…
Critical Quantum Sensing: a tutorial on parameter estimation near quantum phase transitions
George Mihailescu, Uesli Alushi, Roberto Di Candia +2
Quantum phenomena offer the possibility of measuring physical quantities with precision beyond classical limits. However, current progress is constrained by scalability, environmen…
Time correlations from steady-state expectation values
Wojciech Górecki, Simone Felicetti, Lorenzo Maccone +1
Recovering properties of correlation functions is typically challenging. On the one hand, experimentally, it requires measurements with a temporal resolution finer than the system'…
Critical quantum metrology in a stabilized two-photon Rabi model
Zu-Jian Ying, Hang-Hang Han, Bo-Jian Li +2
We investigate a generalized quantum Rabi model (QRM) with two- and four-photon terms with respect to applications for non-linear critical quantum metrology. In the introduced mode…
Nonlinearity-driven Topology via Spontaneous Symmetry Breaking
Alessandro Coppo, Alexandre Le Boité, Simone Felicetti +1
Topology and nonlinearity are deeply connected. However, whether topological effects can arise solely from the structure of nonlinear interaction terms, and the nature of the resul…
Analog Quantum Teleportation
Uesli Alushi, Simone Felicetti, Roberto Di Candia
Digital teleportation protocols make use of entanglement, local measurements and a classical communication channel to transfer quantum states between remote parties. We consider an…
Criticality-Enhanced Quantum Sensing with a Parametric Superconducting Resonator
Guillaume Beaulieu, Fabrizio Minganti, Simone Frasca +4
Quantum metrology, a cornerstone of quantum technologies, exploits entanglement and superposition to achieve higher precision than classical protocols in parameter estimation tasks…
Interplay between time and energy in bosonic noisy quantum metrology
Wojciech Górecki, Francesco Albarelli, Simone Felicetti +2
Quantum entanglement and coherence often allow for protocols that outperform classical ones in estimating a system's parameter. When using infinite-dimensional probes (such as a bo…
Collective quantum enhancement in critical quantum sensing
Uesli Alushi, Alessandro Coppo, Valentina Brosco +2
Critical systems represent a valuable resource in quantum sensing and metrology. Critical quantum sensing (CQS) protocols can be realized using finite-component phase transitions,…
Optimality and Noise-Resilience of Critical Quantum Sensing
Uesli Alushi, Wojciech Górecki, Simone Felicetti +1
We compare critical quantum sensing to passive quantum strategies to perform frequency estimation, in the case of single-mode quadratic Hamiltonians. We show that, while in the uni…
Observation of first- and second-order dissipative phase transitions in a two-photon driven Kerr resonator
Guillaume Beaulieu, Fabrizio Minganti, Simone Frasca +4
In open quantum systems, first- and second-order dissipative phase transitions (DPTs) can emerge in the thermodynamic limit from the competition between unitary evolution, driving…
