There are few topics more intimidating than quantum computing.
For one, the key principles involved — like, for instance, the idea that atoms can exist in two different states at once — are utterly bizarre. And the concept of a quantum computer is so different from the computers we use everyday that the field as a whole can seem impenetrable.
Helpfully, the folks at PhD Comics and Caltech's Institute for Quantum Information and Matter have made this excellent cartoon that explains the field in six minutes. Using basic terms, it clearly describes the all the key ideas: quantum mechanics, qubits, entanglement, interference, and the possible applications of these machines.

We're here to shed some clarity
One of our core beliefs here at Vox is that everyone needs and deserves access to the information that helps them understand the world, regardless of whether they can pay for a subscription. With the 2024 election on the horizon, more people are turning to us for clear and balanced explanations of the issues and policies at stake. We’re so grateful that we’re on track to hit 85,000 contributions to the Vox Contributions program before the end of the year, which in turn helps us keep this work free. We need to add 2,500 contributions this month to hit that goal.
Will you make a contribution today to help us hit this goal and support our policy coverage? Any amount helps.
