Part 3: Quantum Amplitudes: The One New Rule
Part 3 adds the only new rule in quantum mechanics: uncertainty described by numbers that can be negative. Amplitudes, the Born rule, an honest definition of superposition, and a minus sign no single measurement can see.

Part 2: The Classical Bit You Don’t Know Yet
Part 2 formalizes the classical bit: a definite value, probabilities that measure your ignorance, and a two-line proof that recordless mixing never un-mixes. Every belief here is true. One of them is about to matter.

Routing Quantum Information: SWAP, iSWAP, and Moving Qubit States
Quantum computers face a unique challenge in moving quantum information between qubits. Unlike classical bits that can be shuttled freely along wires, qubits cannot be arbitrarily copied or moved due to the no-cloning theorem. To route a qubit’s state from…

Surface Code Quantum Error Correction
Quantum error correction (QEC) is indispensable for building large-scale fault-tolerant quantum computers. Even today’s best qubits suffer error rates that would quickly corrupt any long calculation if left uncorrected. The principle of QEC is to encode a single logical qubit…
