Quantum Physics in Action
Like Duolingo, but for Quantum Physics in Action. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through The Quantum in Your Pocket, Precision and Sensing, The Future of Information, and Materials and Energy. It assumes you already know the basics.

Key ideas in Quantum Physics in Action
- Semiconductors have a narrow band gap that allows thermal or electrical energy to promote electrons.
- Insulators have a large energy gap that prevents electrons from jumping to the conduction band.
- How energy band gaps dictate a material's electrical behavior
- Doping introduces impurities that shift the Fermi level to create excess charge carriers.
- A P-N junction creates a built-in potential barrier that controls the direction of current.
- The mechanism of doping and P-N junction formation
- The gate voltage modulates the height of the potential barrier between the source and drain.
- Transistors act as switches by toggling between a quantum-allowed and a quantum-forbidden state.
- Quantum tunneling allows electrons to pass through barriers that are physically too thin to stop them.
- Tunneling probability increases exponentially as the thickness of the insulating layer decreases.
- The transistor's role as a quantum-controlled gate
- Wrapping the gate around three sides of the channel provides better electrostatic control.
- Quantum confinement in the narrow fin raises the energy levels to suppress unwanted electron flow.
- The impact of electron tunneling on chip miniaturization
- How FinFET architecture uses quantum confinement to improve performance
- External energy pumping is required to overcome the Boltzmann distribution
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Quantum Physics in Action the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
Why doesn't electricity flow through an insulator like diamond as easily as it does through a semiconductor?
