Implementing smooth functions of a Hermitian matrix on a quantum computer
Sathyawageeswar Subramanian, Steve Brierley, Richard Jozsa
We review existing methods for implementing smooth functions f(A) of a sparse Hermitian matrix A on a quantum computer, and analyse a further combination of these techniques which…

Accelerated Variational Quantum Eigensolver
Daochen Wang, Oscar Higgott, Stephen Brierley
The problem of finding the ground state energy of a Hamiltonian using a quantum computer is currently solved using either the quantum phase estimation (QPE) or variational quantum…
