Physicists often think of a qubit like a little globe, with [0] at the north pole and [1] at the south pole, and the qubit’s configuration is represented by a point on the globe.
Key facts
- At a low level, a computer represents information as a series of “bits
- A qubit that was situated on the equator will measure as [0] 50 percent of the time and [1] the other 50 percent of the time
- In their qubits, electricity sloshes around the circuit at a lower or higher energy to encode the quantum version of [0] and [1]

Summary
Editor’s Note: Do you ever feel like a fish out of water? Quantum computing sounds like something out of a sci-fi movie. The Keyword’s first Techspert is Marissa Giustina, a research scientist and quantum electronics engineer in their Santa Barbara office. What do they need to know about conventional computers when they think about quantum computers? At a first glance, “information” seems like an abstract concept.
