| dc.description | Device and semi-device-independent private quantum randomness generators are crucial for applications requiring private randomness. However, they are vulnerable to
detection inefficiency attacks and this limits severely their usage for practical purposes. Here, we present a method for protecting semi-device-independent private
quantum randomness generators in prepare-and-measure scenarios against detection
inefficiency attacks. The key idea is the introduction of a blocking device that adds
failures in the communication between the preparation and measurement devices. We
prove that, for any detection efficiency, there is a blocking rate that provides protection against these attacks. We experimentally demonstrate the generation of private
randomness using weak coherent states and standard avalanche photo-detectors. | |
