Obfuscation of Pseudo-Deterministic Quantum Circuits. (arXiv:2302.11083v1 [quant-ph] CROSS LISTED)
cs.CR updates on arXiv.org arxiv.org
We show how to obfuscate pseudo-deterministic quantum circuits, assuming the
quantum hardness of learning with errors (QLWE) and post-quantum virtual
black-box (VBB) obfuscation for classical circuits. Given the classical
description of a quantum circuit $Q$, our obfuscator outputs a quantum state
$\ket{\widetilde{Q}}$ that can be used to evaluate $Q$ repeatedly on arbitrary
inputs.
Instantiating the VBB obfuscator for classical circuits with any candidate
post-quantum indistinguishability obfuscator gives us the first candidate
construction of indistinguishability obfuscation for all polynomial-size
pseudo-deterministic quantum …
