TEN WORDS THAT UNLOCK EVERY QUANTUM ARTICLE 📖

Save this one.

• Qubit — quantum bit; can be in a blend of 0 and 1
• Superposition — that blend
• Amplitude — the weight behind each outcome (can be negative!)
• Interference — amplitudes adding up or cancelling out
• Entanglement — two or more qubits whose outcomes are linked
• Gate — one operation on qubits (H, X, CNOT...)
• Circuit — gates in sequence; a quantum program
• Measurement — reading a qubit; forces a plain 0 or 1
• Decoherence — the environment "measuring" your qubits by accident; the enemy
• Error correction — using many physical qubits to make one reliable logical qubit

Any of these deserve a deeper dive? Comment and we'll write it up.
