Simultaneous Perturbation Stochastic Approximation of the Quantum Fisher Information

Julien Gacon, Christa Zoufal, Giuseppe Carleo +1

The Quantum Fisher Information matrix (QFIM) is a central metric in promising algorithms, such as Quantum Natural Gradient Descent and Variational Quantum Imaginary Time Evolution.…

Efficient calculation of gradients in classical simulations of variational quantum algorithms

Tyson Jones, Julien Gacon

Calculating the energy gradient in parameter space has become an almost ubiquitous subroutine of variational near-term quantum algorithms. "Faithful" classical emulation of this su…

Quantum-Enhanced Simulation-Based Optimization

Julien Gacon, Christa Zoufal, Stefan Woerner

In this paper, we introduce a quantum-enhanced algorithm for simulation-based optimization. Simulation-based optimization seeks to optimize an objective function that is computatio…

Iterative Quantum Amplitude Estimation

Dmitry Grinko, Julien Gacon, Christa Zoufal +1

We introduce a new variant of Quantum Amplitude Estimation (QAE), called Iterative QAE (IQAE), which does not rely on Quantum Phase Estimation (QPE) but is only based on Grover's A…
