Quantum memories with zero-energy Majorana modes and experimental constraints
Matteo Ippoliti, Matteo Rizzi, Vittorio Giovannetti +1
In this work we address the problem of realizing a reliable quantum memory based on zero-energy Majorana modes in the presence of experimental constraints on the operations aimed a…
Passive states optimize the output of bosonic Gaussian quantum channels
Giacomo De Palma, Dario Trevisan, Vittorio Giovannetti
An ordering between the quantum states emerging from a single mode gauge-covariant bosonic Gaussian channel is proven. Specifically, we show that within the set of input density ma…
Non-Markovian continuous-time quantum walks on lattices with dynamical noise
Claudia Benedetti, Fabrizio Buscemi, Paolo Bordone +1
We address the dynamics of continuous-time quantum walks on one-dimensional disordered lattices inducing dynamical noise in the system. Noise is described as time-dependent fluctua…
Experiments testing macroscopic quantum superpositions must be slow
Andrea Mari, Giacomo De Palma, Vittorio Giovannetti
We consider a thought experiment where the preparation of a macroscopically massive or charged particle in a quantum superposition and the associated dynamics of a distant test par…
Building versatile bipartite probes for quantum metrology
Alessandro Farace, Antonella De Pasquale, Gerardo Adesso +1
We consider bipartite systems as versatile probes for the estimation of transformations acting locally on one of the subsystems. We investigate what resources are required for the…
Quantum Estimation via Sequential Measurements
Daniel Burgarth, Vittorio Giovannetti, Airi N. Kato +1
The problem of estimating a parameter of a quantum system through a series of measurements performed sequentially on a quantum probe is analyzed in the general setting where the un…
