'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.
