Nearly optimal polynomial approximations for the quantum singular value transform
Evan Rule
We introduce polynomial approximations of the even and odd step functions on the interval with simple Chebyshev coefficients, making their numerical implementation straigh…
CaRBM: A Fixed-Depth Quantum Algorithm with Partial Correction for Thermal State Preparation
Omar Alsheikh, A. F. Kemper, Ermal Rrapaj +2
We introduce the CaRBM algorithm for fixed-depth thermal state preparation. Our algorithm is based on thermal state purification and uses the Restricted Boltzmann Machine (RBM) blo…
Recursive algorithm for constructing antisymmetric fermionic states in first quantization mapping
E. Rule, I. A. Chernyshev, I. Stetcu +2
We devise a deterministic quantum algorithm to produce antisymmetric states of single-particle orbitals in the first quantization mapping. Unlike sorting-based antisymmetrization a…
Simplified projection on total spin zero for state preparation on quantum computers
Evan Rule, Ionel Stetcu, Joseph Carlson
We introduce a simple algorithm for projecting on states of a many-body system by performing a series of rotations to remove states with angular momentum projections greater…
Exact block encoding of imaginary time evolution with universal quantum neural networks
Ermal Rrapaj, Evan Rule
We develop a constructive approach to generate quantum neural networks capable of representing the exact thermal states of all many-body qubit Hamiltonians. The Trotter expansion o…
