Session 3 - Quantum Computing and Cybersecurity Lecture Series (March 14, 2026)
From Quantum Computing and Cybersecurity Lecture Series
Executive Summary
The episode provides a foundational overview of quantum mechanics, tracing its history from early 20th-century physicists like Planck and Einstein to the modern principles of quantum computing.
Core quantum phenomena such as wave-particle duality (illustrated by the double-slit experiment), superposition, and entanglement are explained as the fundamental building blocks for quantum computation.
The discussion covers the practical implementation of quantum computers, detailing the concept of qubits, the function of quantum gates like the Hadamard gate, and the significant hardware challenge of maintaining coherence.
Key applications are highlighted, particularly Quantum Key Distribution (QKD) for secure communications, showcasing the potential real-world impact of quantum technologies on cybersecurity.
