Cryptography from pseudorandom quantum states

P Ananth, L Qian, H Yuen - Annual International Cryptology Conference, 2022 - Springer
Pseudorandom states, introduced by Ji, Liu and Song (Crypto'18), are efficiently-computable
quantum states that are computationally indistinguishable from Haar-random states. One …

Wasserstein complexity of quantum circuits

L Li, K Bu, DE Koh, A Jaffe, S Lloyd - arXiv preprint arXiv:2208.06306, 2022 - arxiv.org
Given a unitary transformation, what is the size of the smallest quantum circuit that
implements it? This quantity, known as the quantum circuit complexity, is a fundamental …

A Meta-Complexity Characterization of Quantum Cryptography

BP Cavalar, E Goldin, M Gray, P Hall - arXiv preprint arXiv:2410.04984, 2024 - arxiv.org
We prove the first meta-complexity characterization of a quantum cryptographic primitive. We
show that one-way puzzles exist if and only if there is some quantum samplable distribution …

NH Chia, KM Chung, TH Huang, JW Shih - arXiv preprint arXiv …, 2024 - arxiv.org
Quantum computing introduces many problems rooted in physics, asking to compute
information from input quantum states. Determining the complexity of these problems has …

A Cryptographic Perspective on the Verifiability of Quantum Advantage

NH Chia, H Fu, F Song, P Yao - arXiv preprint arXiv:2310.14464, 2023 - arxiv.org
In recent years, achieving verifiable quantum advantage on a NISQ device has emerged as
an important open problem in quantum information. The sampling-based quantum …
