Quantum Metrology Assisted with Abstention
B. Gendra, E. Ronco-Bonvehi, J. Calsamiglia +2
The main goal of quantum metrology is to obtain accurate values of physical parameters using quantum probes. In this context, we show that abstention, i.e., the possibility of gett…
Growth of graph states in quantum networks
Martí Cuquet, John Calsamiglia
We propose a scheme to distribute graph states over quantum networks in the presence of noise in the channels and in the operations. The protocol can be implemented efficiently for…
Robust optimal quantum learning without quantum memory
G. Sentís, J. Calsamiglia, R. Munoz-Tapia +1
A quantum learning machine for binary classification of qubit states that does not require quantum memory is introduced and shown to perform with the minimum error rate allowed by…
Beating noise with abstention in state estimation
Bernat Gendra, Elio Ronco-Bonvehi, John Calsamiglia +2
We address the problem of estimating pure qubit states with non-ideal (noisy) measurements in the multiple-copy scenario, where the data consists of a number N of identically prepa…
