Single-shot ToF sensing with sub-mm precision using conventional CMOS sensors
Manuel Ballester, Heming Wang, Jiren Li +2
We present a novel single-shot interferometric ToF camera targeted for precise 3D measurements of dynamic objects. The camera concept is based on Synthetic Wavelength Interferometr…
State Discrimination with Post-Measurement Information
Manuel A. Ballester, Stephanie Wehner, Andreas Winter
We introduce a new state discrimination problem in which we are given additional information about the state after the measurement, or more generally, after a quantum memory bound…
Entropic uncertainty relations and locking: tight bounds for mutually unbiased bases
Manuel A. Ballester, Stephanie Wehner
We prove tight entropic uncertainty relations for a large number of mutually unbiased measurements. In particular, we show that a bound derived from the result by Maassen and Uffin…
Separable Measurement Estimation of Density Matrices and its Fidelity Gap with Collective Protocols
E. Bagan, M. A. Ballester, R. D. Gill +2
We show that there exists a gap between the performance of separable and collective measurements in qubit mixed-state estimation that persists in the large sample limit. We charact…
Optimal full estimation of qubit mixed states
E. Bagan, M. A. Ballester, R. D. Gill +2
We obtain the optimal scheme for estimating unknown qubit mixed states when an arbitrary number N of identically prepared copies is available. We discuss the case of states in the…
Purity estimation with separable measurements
E. Bagan, M. A. Ballester, R. Munoz-Tapia +1
Given a large number N of copies of a qubit state of which we wish to estimate its purity, we prove that separable-measurement protocols can be as efficient as the optimal joint-me…
