Double-bracket quantum algorithms for quantum imaginary-time evolution
Marek Gluza, Jeongrak Son, Bi Hong Tiang +5
Efficiently preparing approximate ground-states of large, strongly correlated systems on quantum hardware is challenging and yet nature is innately adept at this. This has motivate…
Exact gradients for linear optics with single photons
Giorgio Facelli, David D. Roberts, Hugo Wallner +3
Though parameter shift rules have drastically improved gradient estimation methods for several types of quantum circuits, leading to improved performance in downstream tasks, so fa…
Double-bracket quantum algorithms for high-fidelity ground state preparation
Matteo Robbiati, Edoardo Pedicillo, Andrea Pasquale +13
Ground state preparation is a central application for quantum computers but remains challenging in practice. In this work, we quantitatively investigate the performance and gate co…
