Harmonic sequence state-preparation
Benjamin Rempfer, Parker Kuklinski, Justin Elenewski +1
We demonstrate an efficient circuit to prepare a quantum state with amplitudes proportional to a harmonic sequence. We do this by first preparing a large quantum state with linearl…

Efficient block-encodings require structure
Parker Kuklinski, Benjamin Rempfer, Justin Elenewski +1
Block-encodings are ubiquitous in quantum computing as a way to represent data within a unitary operator. While several unstructured methods are applicable to arbitrary data, these…

A simpler Gaussian state-preparation
Parker Kuklinski, Benjamin Rempfer, Kevin Obenland +1
The ability to efficiently state-prepare Gaussian distributions is critical to the success of numerous quantum algorithms. The most popular algorithm for this subroutine (Kitaev-We…
