Abstract
Methods, systems, and apparatus for verifying quantum randomness. In one aspect a computing device receives data from a quantum computer. The data includes a timestamp, a binary-valued vector, and a predicted response to a challenge string. The predicted response to the challenge string is generated using a regression model that has been trained to fit LPN instances as a linear function, where the LPN instances are constructed using a physically unclonable function. The computing device determines a parity of a random number output by a public source of randomness at a time specified by the timestamp and performs either a generation round or a test round based on the parity to verify the randomness of a bit generated by the quantum computer. The generation round uses the data to verify a preimage of the binary-valued vector and the test round uses the data to verify an equation.
