How to Construct Quantum Random Functions
... Goldreich, Goldwasser, and Micali show how to build a pseudorandom function PRF from any length-doubling pseudorandom generator G. This construction is known as the GGM construction. Pseudorandom generators can, in turn, be built from any one-way function, as shown by Håstad et al. [HILL99]. The se ...

For example, in GRW the fundamental dynamical law specifies the chances that the quantum state of a system evolves to one among a range of subsequent states. The laws may be local in that the probability of a system whose state i ...
