Efficient Construction of Statistically Secure Pseudorandom States and Commitments in the Common Haar State Model
The authors construct a statistically secure pseudorandom state generator in the common Haar state model, where the output length is strictly larger than the key size. They also construct an unconditionally secure quantum commitment scheme in the same model.
Constructing and Separating Quantum Pseudorandomness from a Single Haar Random State
A single Haar random quantum state can be used to construct single-copy pseudorandom states (1PRS), which are computationally indistinguishable from a Haar random state for a single copy. However, this single Haar random state is not sufficient to construct the stronger notion of (multi-copy) pseudorandom states (PRS).
Quantum One-Way State Generators Imply Quantum Commitments
Quantum one-way state generators (OWSGs) with O(n/log(n)) copies are equivalent to quantum commitments and to polytime-copy OWSGs. The weakest OWSGs from which quantum commitments can be obtained are those with O(n/log(n)) copies.
