A multiprotocol and multiplatform quantum random number generation framework
Random numbers are everywhere.
Computer algorithms, data encryption, physical simulations, and even the arts use them all the time. There is one problem though: it turns out that they are actually very difficult to produce in large amounts. Classical computers can only implement mathematical tricks to emulate randomness, while measuring it out of physical processes turns out to be too slow. Luckily, the probabilistic nature of quantum computers makes these devices particularly useful for the task.
QRAND is a free and open-source framework for quantum random number generation. Thanks to its loosely coupled design, it offers seamlessly compatibility between different quantum computing platforms and QRNG protocols. Not only that, but it also enables the creation of custom cross-compatible protocols, and a wide range of output formats (e.g. bitstring, int, float, complex, hex, base64).
To boost its efficiency, QRAND makes use of a concurrent cache to reduce the number of internet connections needed for random number generation; and for quality checks, it incorporates a suite of classical entropy validation tests which can be easily plugged into any base protocol.
Additionally, QRAND introduces an interface layer for NumPy that enables the efficient production of quantum random numbers (QRN) adhering to a wide variety of probability distributions. This is ultimately accomplished by transforming uniform probability distributions produced in cloud-based real quantum hardware, through NumPy's random module.

# ...As of June 2021, QRAND supports Qiskit and Q#. However, support for Cirq is under active development.
As of June 2021, both the basic HadamardProtocol, and the more sophisticated EntanglementProtocol are available. We are also working on implementing a version of Google's Sycamore routine (patent permitting).
