Quantum Technology: From Fundamentals to Applications (NUS)

The Centre for Quantum Technologies at the National University of Singapore is one of Asia’s flagship quantum research institutions and a major node in the global quantum technology ecosystem. This course was developed by CQT researchers who work across quantum computing, quantum cryptography, and quantum sensing, and it shows in how evenly the course treats the full breadth of quantum technology rather than concentrating only on quantum computing as many courses do.

The course is designed as a bridge. It assumes enough scientific background to engage with the underlying physics and mathematics, but its goal is to bring students to the point where they can understand and evaluate real quantum technology systems and follow the rapidly evolving landscape of applications and commercial development.

What you’ll learn

The first two weeks establish the quantum mechanical foundations: superposition, entanglement, measurement, and the Bloch sphere representation of a qubit. These concepts are introduced with enough mathematical rigor to support the applications covered later, but the emphasis is on physical intuition and applicability rather than formal derivation.

The middle weeks cover the four main pillars of quantum technology in turn. Quantum computing is addressed through the circuit model, with the role of interference and entanglement in quantum speedup explained clearly. Quantum cryptography focuses on QKD protocols and their security guarantees, contrasting them with classical and post-quantum cryptographic approaches. Quantum sensing explains how quantum coherence enables measurement precision beyond the standard quantum limit, with applications in atomic clocks, gravitational sensors, and medical imaging. Quantum communication covers the fundamentals of quantum networks and the path toward a quantum internet. The final week surveys the current commercial and policy landscape, discussing where quantum advantage has been demonstrated and where it remains a goal.

Who is this for

This course is well suited to science and engineering professionals who want to understand quantum technology broadly rather than specialize in one area. It is also a strong choice for business leaders, investors, and policy professionals who need technical literacy in quantum technology, and for students preparing to specialize who want a map of the full field before diving into one corner of it.

Prerequisites

A working knowledge of undergraduate physics or a closely related quantitative field is the practical minimum. Linear algebra at the level of vectors and matrix multiplication is used throughout. No prior quantum mechanics is required; the course introduces the necessary concepts from scratch. No programming experience is needed for the core content.
