Quantum Interactive Proof Systems
Quantum Interactive Proof Systems (QIP) are a fascinating part of quantum computational complexity theory, exploring the limits of what can be proven (or verified) using quantum mechanics. To understand QIP,….

Quantum Space Complexity
Just as classical computing has space complexity—the measure of how much memory a computer uses—quantum computing has its own notion of space complexity. This concept is crucial to understanding how….
Syndrome Measurement
Syndrome measurement is the process of detecting which error (if any) has affected a quantum state—without destroying the quantum information itself. In simple terms: Syndrome measurement is like a quantum….
Surface Codes
Surface codes are one of the most promising methods for quantum error correction (QEC). In simple terms, they are used to protect quantum information from errors — which is essential….
Quantum Error Correction
1. Why Do We Even Need Error Correction in Quantum Computing? In classical computing: In quantum computing: But unlike classical bits, you can’t just copy a qubit or measure it….
