Efficient Learning of Quantum States Prepared With Few Non-Clifford Gates

2023 · arXiv (Cornell University)

We give a pair of algorithms that efficiently learn a quantum state prepared by Clifford gates and $O(\log n)$ non-Clifford gates. Specifically, for an $n$-qubit state $|ψ\rangle$ prepared with at most $t$ non-Clifford gates, our …

Decoding articulatory and phonetic components of naturalistic continuous speech from the distributed language network

2023 · Journal of Neural Engineering

Abstract Objective. The speech production network relies on a widely distributed brain network. However, research and development of speech brain–computer interfaces (speech-BCIs) has typically focused on decoding speech only from superficial subregions readily accessible by …
