What are Quantum Processing Units? Types, Opportunities and Challenges
In this video, we delve into the fascinating world of Quantum Processing Units (QPUs), the heart of quantum computers. Unlike classical CPUs, QPUs use qubits, which leverage quantum mechanics to perform complex computations faster.
We'll explore various QPU architectures, including neutral atoms, superconducting circuits, trapped ions, and photonic systems, highlighting their unique advantages and challenges. Discover the significant supporting infrastructure required for QPUs, such as dilution refrigerators and specialized control systems.
Despite their potential to revolutionize computing by solving classically intractable problems, QPUs face environmental sensitivity, scalability, and connectivity challenges. Learn how researchers are addressing these issues and what the future holds for quantum computing.
