How to Create a Quantum Computer

If quantum physics is the theory and math is the language, then engineering is the sheer force of will required to build a "starship" out of subatomic particles.

This episode moves out of the abstract and into the lab to explore the monumental task of building a physical quantum computer.

We dive into the "cryogenic challenge"—the necessity of cooling superconducting qubits to temperatures colder than deep space just to keep them from "leaking" information into the environment.

Learn about the "wiring bottleneck" as engineers struggle to connect thousands of control lines to a chip the size of a fingernail, and the high-stakes world of quantum error correction where a single "logical" qubit might require hundreds of physical ones to stay stable.

From dilution refrigerators to microwave control pulses, discover what it truly takes to shield a fragile quantum state from the noisy clamor of our ordinary world.
