Takeaways for Quantum Developers

Today, you can

○ use JS to learn (visually and code) ○ invoke real quantum processors for free ○ Use AI and optimization techniques on small problems

Takeaways for Quantum Developers

Tomorrow, you should (might want to)

○ Beware of traditional encryption ○ Understand how to map hard problems into Q-solvable ones

For now, we must wait for Quantum Supremacy
