Quantum Computing Basics

Computing using quantum mechanical phenomena.

How it works

Quantum computers use qubits and interference to solve certain problems faster; they are probabilistic and not simply "try everything at once". Current devices are noisy (NISQ).

Where it is used

Chemistry simulation, cryptanalysis, optimization research.

Common pitfall

Quantum advantage applies to specific problems only.

Where it fits in the course

Quantum Computing Basics is topic 23 of 51 in Emerging & Frontier Topics, rated Intermediate. It follows Decentralized Applications. The next topic is Qubits and Superposition.
