-efficient unitary synthesis via block-sparse Hamiltonian simulation
Diyi Liu, Shuchen Zhu, Wibe Albert de Jong +3
We construct Clifford+ circuits implementing arbitrary -qubit unitaries with worst-case -count at constant operator-norm error, where , imp…
Exponentially Compressed and Garbage-Free Alias Sampling for Polynomial State Preparation
Diyi Liu, Hanyu Wang, Shuchen Zhu +4
Coherent alias sampling implement an important subroutine for block encoding and qubitization based quantum simulation using quantum lookup table. Related constructions exploit dat…
Clifford-efficient sparse state preparation for molecular wavefunctions
Yingrong Chen, Nathan A. Baker, Rushi Gong +7
Sparse quantum state preparation concerns an -qubit target state that is a superposition of only computational basis states. Existing approaches exploit this sparsit…
QDK/Chemistry: A Modular Toolkit for Quantum Chemistry Applications
Nathan A. Baker, Brian Bilodeau, Chi Chen +23
We present QDK/Chemistry, a software toolkit for quantum chemistry workflows targeting quantum computers. The toolkit addresses a key challenge in the field: while quantum algorith…
A circuit-generated quantum subspace algorithm for the variational quantum eigensolver
