Quantum Resources Required to Block-Encode a Matrix of Classical Data

2022 · arXiv (Cornell University)

We provide modular circuit-level implementations and resource estimates for several methods of block-encoding a dense $N\times N$ matrix of classical data to precision $ε$; the minimal-depth method achieves a $T$-depth of $\mathcal{O}{(\log (N/ε))},$ while the …
