QLY QUANTUM COURSE

Quantum algorithms, run for real.

A course you actually take. Work through the hands-on track below to build and run real circuits in your browser with instant feedback, then watch the lecture series where each algorithm is executed live on a backend and explained from the measured results. No installs, no hand-waving.

HANDS-ON TRACKAUTO-GRADED6 LESSONS · ~70 MIN

Learn by doing: write & run real circuits

Every lesson gives you a live editor and a circuit you build yourself — checked automatically the instant you run it, right in the browser. Go from your first qubit to superposition, interference, entanglement and a Grover search you complete step by step. Progress is saved as you go.

Grover's search: find the needle in 2 steps

Start from a blank editor, ask Qpilot for a Grover circuit that finds |101⟩ in a 3-qubit search space, and watch it plan the oracle, generate the code, and run 512 shots. Follow the cursor through the whole flow: the marked state comes back at 94.7%, against a theoretical 94.5%, and Qpilot walks through why two iterations is optimal.

GHZ states: entanglement beyond two qubits

One prompt entangles five qubits. Qpilot proposes the circuit as a reviewable diff, 512 shots run on SV1, and the histogram shows |00000⟩ and |11111⟩ splitting 52.0% / 48.0% with zero counts anywhere else. Qpilot then walks through why measuring one qubit decides all five.

Quantum teleportation, gate by gate

Prepare |1⟩ on Alice's qubit, entangle an EPR pair, and let deferred measurement carry the corrections. Across all 512 shots Bob's qubit reads 1 in every single one, with zero counts anywhere else. Qpilot explains why the state always arrives even though Alice's bits come out random.

QAOA: optimization on a quantum computer

MaxCut on a 4-node ring with two QAOA layers and tuned angles: γ = (π/4, 5π/8), β = (3π/8, π/4). All 512 shots land on the two perfect cuts, |0101⟩ and |1010⟩, with zero counts on the other 14 states. Qpilot explains what the cost and mixer layers each contribute, and why depth buys concentration.

Shor's algorithm: factoring 15 for real

The famous one. A compiled period-finding circuit (4 counting + 4 work qubits, 62 CX) runs 512 shots and every single one lands on a period peak: counting values 0, 4, 8, 12 → r = 4. The classical finish on camera: gcd(7²±1, 15) = 3 and 5. That's the algorithm that changed cryptography, on your screen.
