Description

This course contains the use of artificial intelligence.

Quantum computing is transitioning from niche research to strategic technology planning. In 2024–2025, vendor roadmaps, maturing error-mitigation research, and post-quantum cryptography timelines are shaping enterprise decisions even before large-scale fault tolerance arrives. Professionals who can interpret capabilities, constraints, and industry narratives are better positioned to evaluate vendors, set realistic expectations, and guide roadmaps.

This theory-first course builds conceptual literacy across quantum information (states, qubits, measurement), circuit models and gate sets, algorithmic families (Grover, variational approaches, Shor’s framework at a high level), noise and decoherence, hardware modalities (superconducting, ion traps, photonics, neutral atoms), and complexity notions (BQP, oracle models). It also frames enterprise patterns—optimization, simulation, and security—and introduces evaluation criteria, resource estimation logic, and quantum-safe migration concepts. No coding, tooling, or cloud lab work is required.
