How Quantum Computers Work
Understand how quantum computers trade simple silicon switches for the strange rules of physics. Explore superposition, entanglement, and how quantum algorithms solve problems that choke standard supercomputers.
Like Duolingo, but for How Quantum Computers Work. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Rethinking the Bit and Harnessing the Quantum Advantage. It starts from scratch.

Key ideas in How Quantum Computers Work
- A classical bit must always be decisively 0 or 1 at any point in time
- Exploring multiple combinations on a classical chip requires checking them one after another
- A qubit in superposition holds a blend or weighted combination of both 0 and 1 at the same time
- Superposition is a definite physical state of possibilities, not just an unknown or hidden classical switch
- Qubits must be crafted out of tiny quantum-scale systems like trapped ions, single photons, or superconducting electrical loops
- Qubits are extremely fragile to ambient heat and noise compared to sturdy everyday silicon transistors
- Measuring a qubit destroys the superposition and forces it to collapse into either a standard 0 or 1
- You can never directly read out the simultaneous blend in a single run; you only ever get one classical bit out
- Writing a quantum program is about steering probabilities so right answers cancel out wrong ones before readout
- Because measurement is probabilistic, quantum programs are run many times over to collect statistical results
- Entangled qubits act as a single connected system rather than isolated objects
- Measuring one entangled qubit instantly fixes the outcome for its partner
- You do not need to measure both qubits independently to know the outcome
- Classical bits add capacity one value at a time
- Each additional qubit doubles the total number of simultaneous states
- Exponential scaling means state space grows by powers of two
