Quantum State Preparation without Coherent Arithmetic
Author(s): Sam McArdle, András Gilyén, and Mario Berta
We introduce a versatile method for preparing a quantum state whose amplitudes are given by some known function. Unlike existing approaches, our method does not require handcrafted reversible arithmetic circuits, or quantum table reads, to encode the function values. Instead, we use a template quant… [Phys.
