Experimental measurement-device-independent quantum random number generation

Reference Resource - Efficient Measurement - Device - Independent Entanglement

Imperfections in experimental measurement schemes can lead to falsely identifying, or over estimating, entanglement in a quantum system. A recent solution to this is to define schemes that are robust to measurement imperfections measurement device independent entanglement witness (MDI-EW). Here we introduce a novel approach for MDI-EW, which significantly reduces the experimental complexity and...

An Elementary Proof of Private Random Number Generation from Bell Inequalities

The field of device-independent quantum cryptography has seen enormous success in the past several years, including security proofs for key distribution and random number generation that account for arbitrary imperfections in the devices used. Full security proofs in the field so far are long and technically deep. In this paper we show that the concept of the mirror adversary can be used to sim...

Experimental study of a quantum random-number generator based on two independent lasers

Entropy Analysis and System Design for Quantum Random Number Generators in CMOS Integrated Circuits

A quantum random number generator is implemented in an integrated circuit without the need for complex, bulky and expensive measurement equipment and circuitry. Quantum entropy, chaotic entropy and pseudo-entropy are defined and their combinations mathematically described. Models and design equations are provided for estimating the quantum entropy in the form of shot noise due to sub-threshold ...
