Error Mitigation Techniques: ZNE, PEC and More
Error mitigation techniques compared, including zero-noise extrapolation, probabilistic error cancellation and dynamical decoupling.
Quantum Coding Theory: Protecting Quantum Information
Quantum coding theory protects quantum information against noise. How quantum codes differ from classical codes, main families and uses.
Quantum Error Detection: Knowing Without Fixing
Quantum error detection flags errors without correcting them. Syndrome measurement, detection codes and their role in fault-tolerant systems.
Quantum Dephasing: How Phase Information Is Lost
Dephasing destroys the phase relation between parts of a superposition without changing populations. Causes, T2 times, measurement and mitigation.
The Quantum Threshold Theorem, Explained
The threshold theorem says arbitrarily long quantum computations are possible if physical error rates stay below a threshold. What that requires.
Quantum Robustness Codes: Surviving Correlated Noise
How error correction codes are adapted to correlated and non-standard noise, from error models and channels to implementation strategies.
Quantum Stabilizer Code Families, Compared
The main families of stabilizer codes compared: history, properties, encoding, recovery, fault tolerance, applications and limitations.
Quantum Interleaved Codes Against Burst Errors
Interleaving spreads a burst of errors across many code blocks so each can correct it. How quantum interleaved codes work and when they help.
Quantum Cyclic Codes: Algebraic Structure for Qubits
Quantum cyclic codes inherit the algebraic structure of classical cyclic codes. How they are encoded and decoded and where they are used.
Quantum Fountain Codes for Lossy Quantum Channels
Quantum fountain codes adapt rateless erasure codes to channels that lose qubits. Their features, applications and development prospects.
Quantum Checksum Codes: Detecting Without Correcting
Quantum checksum codes detect errors without correcting them, the way classical checksums do. How they work and how they compare with classical ones.
