What Every Microwave Engineer Should Know About Quantum Computing

Abstract: Quantum computation promises to transform society as profoundly as any previous technological revolution in human history. Certain computations that are completely intractable for present day and any conceivable future classical supercomputer may become practical by harnessing the immense power of quantum mechanics through the engineering and control of interacting two-level quantum bits, or qubits.

Microwaves play a fundamental role in qubit state initialization, superposition, entanglement, general manipulation, and readout for implementing quantum algorithms, in many of the most promising qubit technologies (e.g. superconducting qubits based on Josephson junctions). Moreover, classical microwave-based electronic control systems featuring scalable, multi-channel, synchronous stimulus response measurements with low-latency feedback may be the key to ultimately realizing practical quantum computers.

This talk introduces the exciting potential, basic principles, and significant technical challenges of practical quantum computation. The emphasis is on the fundamental role of microwaves and microwave engineering in the design and physical realization of quantum technologies. The emergence of a new “quantum engineering” discipline represents an exciting opportunity for the present and next generation of physical scientists, computer scientists, and microwave engineers.
