Pauli transfer matrix direct reconstruction: channel characterization without full process tomography
Simone Roncallo, Lorenzo Maccone, Chiara Macchiavello
We present a tomographic protocol for the characterization of multiqubit quantum channels. We discuss a specific class of input states, for which the set of Pauli measurements at t…
Multiqubit noise deconvolution and characterization
Simone Roncallo, Lorenzo Maccone, Chiara Macchiavello
We present a noise deconvolution technique for obtaining noiseless expectation values of noisy observables at the output of multiqubit quantum channels. For any number of qubits or…
When does a particle arrive?
Simone Roncallo, Krzysztof Sacha, Lorenzo Maccone
We compare the proposals that have appeared in the literature to describe a measurement of the time of arrival of a quantum particle at a detector. We show that there are multiple…
