Introduction to Quantum Error Models
A practical introduction to the main quantum error models: bit flip, phase flip, depolarizing, and amplitude damping. Understand how these map onto real hardware noise and how error correction addresses each.
- →
- intermediate
- 22 min read
Introduction to Quantum Error Correction: The Bit-Flip Code
Learn how quantum error correction works by implementing the 3-qubit bit-flip code in Qiskit - encode a logical qubit, introduce an error, detect it with syndrome measurement, and correct it.
- →
- intermediate
- 16 min read
Quantum Error Correction: Building a 3-Qubit Repetition Code in Qiskit
Implement a 3-qubit bit-flip repetition code from scratch in Qiskit: encoding, error injection, syndrome measurement with ancilla qubits, decoding logic, and fidelity benchmarking across error rates.
