Nonlocal Quantum Phase Transitions
Alessandro Coppo, Aanal Jayesh Shah, Hadiseh Alaeian +3
Phase transitions are paradigmatic examples of emergent phenomena, in which symmetries present at the microscopic level can be spontaneously broken in the thermodynamic limit. Two…
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…
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'…
