Optimizing and Comparing Quantum Resources of Statistical Phase Estimation and Krylov Subspace Diagonalization
Oumarou Oumarou, Pauline J. Ollitrault, Stefano Polla +1
We develop a framework that enables direct and meaningful comparison of two early fault-tolerant methods for the computation of eigenenergies, namely \gls{qksd} and \gls{spe}, with…

Phase shift rule with the optimal parameter selection
L. A. Markovich, S. Malikis, S. Polla +1
The phase shift rules enable the estimation of the derivative of a quantum state with respect to phase parameters, providing valuable insights into the behavior and dynamics of qua…
