'EXPLORING THE QUANTUM SPEED LIMIT WITH ONLINE PLAYERS'

Abstract:
An online platform Quantum Moves (www.scienceathome.org) was created to
gamify optimization problems in quantum physics. Quantum Moves aims to
use human players to find solutions to a class of quantum optimal
control problems. Around 140,000 players of Quantum Moves have helped us
discover novel solution strategies which numerical optimizations fail to
find, and push the quantum speed limit for atomic transport problems.
Remarkably, top players are able to outperform state-of-the-art
Krotov-based optimization algorithms.

A follow-up project studies how humans learn to solve the gamified
quantum optimization problem; preliminary analysis of around 800 players
highlights the crucial role of heuristics and the ability of humans to
create a low-dimensional representation of the complex task they are
presented with. Further studies dive deeper into dimensionality
reduction of complex optimization landscapes of the type encountered
here, and into the use of human in other types of optimization problems.
This will form first steps in the efficient training of novel machine
learning algorithms we will develop in the future for solving quantum
optimal control problems.
