We derive fidelity tradeoffs for probabilistic minimal disturbance measurements for certain discrete sets of symmetrical single qubit states. We propose and experimentally demonstrate a simple linear optical scheme saturating these tradeoffs in which the degree of disturbance is controlled only by measurement of a single ancillary photon.

Abstract

We derive fidelity tradeoffs for probabilistic minimal disturbance measurements for certain discrete sets of symmetrical single qubit states. We propose and experimentally demonstrate a simple linear optical scheme saturating these tradeoffs in which the degree of disturbance is controlled only by measurement of a single ancillary photon.
