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…
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, Wojciech Górecki, Simone Felicetti +2
Recovering properties of correlation functions is typically challenging. On the one hand, experimentally, it requires measurements with a temporal resolution finer than the system'…
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…
