Quantum Computing
Qubits, superposition, gates, and measurement.

- Qubits & SuperpositionA qubit isn't just 0 or 1 — it's a combination of both until you measure it.medium
- Quantum MeasurementThe act of observing that collapses a superposition into a definite state — and why it's probabilistic.medium
- Quantum GatesGates are reversible operations that rotate a qubit's state — the instructions of a quantum circuit.medium
- EntanglementWhen two qubits become linked so that measuring one instantly decides the state of the other — no matter the distance.hard
- Quantum AlgorithmsBeyond the basics — how algorithms like Shor's and Grover's use quantum effects to solve problems classical computers can't.hard
- Superposition & the Bloch SphereAmplitudes, normalization, and a geometric picture — every single-qubit state is a point on the Bloch sphere.medium
- Quantum CircuitsHow to read circuit diagrams and compose gates into circuits that act on one or two qubits.medium
- Quantum TeleportationMove an unknown quantum state to a distant qubit using a shared Bell pair and two classical bits.hard
- Quantum Error CorrectionDecoherence threatens every qubit — the 3-qubit bit-flip code shows how redundancy and syndrome measurement fight back.hard
- Quantum Gate ReferenceA catalog of the workhorse gates — single-qubit rotations and the multi-qubit controlled gates — with their matrices and exactly what they do.medium
- Shor's Algorithm & Breaking RSAFactoring large numbers is the rock RSA stands on — Shor's algorithm reduces factoring to period finding and cracks it in polynomial time.hard
