T-count optimization of approximate quantum Fourier transform
Byeongyong Park, Doyeol Ahn
The quantum Fourier transform (QFT) is a ubiquitous quantum operation that is used in numerous quantum computing applications. The major obstacle to constructing a QFT circuit is t…

A tripartite entanglement in de Sitter spacetime
Sang-Eon Bak, Paul M. Alsing, Warner A. Miller +2
We investigate the quantum correlation for tripartite entangled states in de Sitter space. First, we adopt the noisy quantum channel model. In this model, the expansion effect is r…
