A simplistic view of the progression of quantum computers has three stages, each with a question: Stage 1: Can quantum computers be built at all, regardless of the quantity and quality of qubits? Stage 2: Can errors be detected and

Some say that there are just two quantum algorithms today: Grover’s and Shor’s. While Shor’s gets all the headlines, Grover’s stands out because of its elegant simplicity. See a beautiful video explaining its operation here, created by 3Blue1Brown. By way

In a week when Google announced it is starting a neutral-atom group, Atomique had two burning questions: Quantuessa will answer the second question. BTW, I sometimes get asked how I came to join QuEra and work on neutral atoms. About

Imagine walking through an auto show and seeing a sleek, glowing concept car. The builder promises it will soon fly you to work while you sleep. That sounds amazing, but the cars actually driving outside are still running on gas

In everyday life, things have definite states. A coin on a table is either heads or tails. But at the quantum scale, particles don’t work that way. A quantum particle like an atom or an electron can be prepared so

In 1935, physicist Erwin Schrödinger proposed a thought experiment to show how strange quantum mechanics really is. Imagine you put a cat in a sealed box with a tiny bit of radioactive material, a detector, and a vial of poison.

A regular computer stores everything as bits, and each bit is either a 0 or a 1. Think of it like a light switch: off or on, nothing in between. A qubit (short for “quantum bit”) is the quantum computing

Quantum advantage is the point where a quantum computer can solve a specific problem faster or better than even the most powerful traditional (classical) computers in the world. This doesn’t mean quantum computers are faster at everything. They won’t load

Today I’m launching a personal project I’ve wanted to ship for a while — quantum comics. Tomorrow, Sunday, and on future Sundays, I’ll post a new “Quantum Bits” strip featuring my two heroines, Quantessa and Atomique. As a kid, I
