Faster Learning under Relaxed Local Differential Privacy
Cristina Butucea, Huiyun Tang, Marie-Luce Taupin
We consider density estimation under the relaxed local differential privacy condition that the privatized distributions are -close in total variation distance. We show that addi…

Optimal estimation of high-dimensional quantum states using locally gentle measurements
Cristina Butucea, Jan Johannes, Henning Stein
We study the task of estimating a dimensional quantum state under the constraint that the measurement is gentle. Such measurements do not collapse the state; they i…
