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…
Privacy in Distributed Quantum Sensing with Gaussian Quantum Networks
Uesli Alushi, Roberto Di Candia
We study the privacy properties of distributed quantum sensing protocols in a Gaussian quantum network, where each node encodes a parameter via a local phase shift. We first show t…
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…
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,…
