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 very same error rate as the op…
Scavenging quantum information: Multiple observations of quantum systems
Peter Rapcan, John Calsamiglia, Ramon Munoz-Tapia +2
Given an unknown state of a qudit that has already been measured optimally, can one still extract any information about the original unknown state? Clearly, after a maximally infor…
Optimal signal states for quantum detectors
Ognyan Oreshkov, John Calsamiglia, Ramon Munoz-Tapia +1
Quantum detectors provide information about quantum systems by establishing correlations between certain properties of those systems and a set of macroscopically distinct states of…
