Predicting quantum channels over general product distributions
Sitan Chen, Jaume de Dios Pont, Jun-Ting Hsieh +3
We investigate the problem of predicting the output behavior of unknown quantum channels. Given query access to an -qubit channel and an observable , we aim to learn the…

On classical inequalities for autocorrelations and autoconvolutions
Jaume de Dios Pont, José Madrid
In this paper we study an autocorrelation inequality proposed by Barnard and Steinerberger. The study of these problems is motivated by a classical problem in additive combinatoric…

A geometric lemma for complex polynomial curves with applications in Fourier restriction theory
Jaume de Dios Pont
The aim of this paper is to prove a uniform Fourier restriction estimate for certain dimensional surfaces in . These surfaces are the image of complex polynomia…
