I would love to live in a world with large, error-corrected quantum computers. But right now we only have noisy, small ones. To illuminate paths or dead-ends towards that goal, much of my work involves applying information and complexity theory to open up new classical-quantum gaps, or study the limitations of near-term quantum devices. I strongly believe that scrutinizing theoretical physics through a computational lens will lead to its next paradigm shift.
