Quantum Mechanics, qubits, superposition & superconductors with Prof. Prabha Mandayam | BP2B S2 E11

Join Prof. Prabha Mandayam on the Best Place to Build Podcast for a deep dive into how a Quantum Computer differ from a Classical Computer. What are Qubits, Quantum States, and Quantum Algorithms? How are Shor’s Algorithm and Grover’s Algorithm changing the future of computing? With this episode, we welcome you to step into the world of Quantum Processors, Quantum Gates, and cutting-edge concepts such as Entanglement, Decoherence, and Quantum Error Correction. What You’ll Learn: * The difference between a Classical Bit and a Quantum Bit (Qubit) * How Transistors and Binary Operations paved the way for modern computing * Types of Qubits: Superconducting Qubits, Photonic Qubits, Trapped Ion Qubits, Neutral Atom Qubits * The challenge of Noise, Decoherence, and why Error Correction matters * How Quantum Communication, Quantum Key Distribution (QKD), and Post-Quantum Cryptography (PQC) are shaping the future of cybersecurity * Emerging fields like Quantum Sensing and Variational Quantum Algorithms Tech giants like Google and IBM, along with research hubs such as IIT Madras, are pushing the boundaries of quantum innovation. Who will win the race to build a practical Quantum Processor? Whether you’re a beginner curious about the basics or a tech enthusiast exploring advanced Quantum Computing concepts, this episode breaks it down in simple, clear terms.
