01 · Foundations

Start here if you're new to quantum computing. This module builds the vocabulary and mental models everything else in QuantumEd relies on — no linear algebra assumed going in.

What's in this module

  • Why Quantum Computing? — the motivation for the field, the classes of problems it targets, and how it differs from classical computing at a conceptual level.
  • What Is Quantum Computing? — qubits, superposition, measurement, and entanglement, each with an interactive demonstration.
  • Quantum Computing Today — the NISQ era, the path to fault tolerance, and today's practical limitations.

Once you've worked through these three pages, move on to 02 · Quantum Computing Fundamentals for the math and circuit model behind the concepts introduced here.
