Approximate Amplitude Encoding with the Adaptive Interpolating Quantum Transform

Gekko Budiutama, Shunsuke Daimon, Xinchi Huang +2

Amplitude encoding of real-world data on quantum computers is often the workflow bottleneck: direct amplitude encoding scales poorly with input size and can offset any speedups in…
