The refrigeration assembly is shown without its cover, and the chip is at the bottom. Using liquid nitrogen and liquid helium stages from top to bottom, it keeps getting colder all the way down to minus degrees Fahrenheit.

Like the D-Wave computer, superconducting materials are used that must be kept at subzero temperatures, and both photos show the covers removed to expose the quantum chip at the bottom.

If a transistor was a Lego, a qubit would be a blob of slime: the two components follow completely different rules , and can be used to build entirely different structures. For example, the circuits can be programmed into a delicate quantum state known as a superposition, where they are equal to neither 1 nor 0, but some combination of the two. Qubits offer a fluidity inaccessible to ordinary computers, which box the world in binary.

As the conductor of my quantum orchestra, I decided what each little superconducting circuit did by dragging brightly colored icons representing commands onto its corresponding line at random. After about a minute, IBM sent me an automated email with my computation results. I examined the final value. Four qubits equaled 0, while a fifth one hovered in a superposition state that was 98 percent equal to 0, and 2 percent equal to 1. Legit researchers, many unaffiliated with IBM, have published more than academic papers using it. The app is part of a larger effort to boost literacy in quantum computing.

Other companies have also been releasing open-source software packages to reach out to the masses—or more probably, nerds with niche interests. They hope that a diverse pool of users can guide them toward more creative uses for the machines.

The packages, predominantly written in Python, strive to make the software as user-friendly as possible with detailed tutorials and interactive apps. Still, by letting everybody in, researchers are hoping that somebody will finally crack the mystery of quantum computing. So far the biggest device, announced Tuesday by Maryland-based startup IonQ, purportedly contains error-prone qubits.

But researchers think these angsty teenage devices still have potential. Google, for example, has a qubit quantum computer that it plans to make available to outside researchers. One of its projects is to promote the use of its computer in drug discovery and materials design, says Google chemist Jarrod McClean. To that end, the company released a software package this year called OpenFermion.

Experts think that quantum computers should be able to simulate chemistry more accurately than conventional computers, since electrons, atoms, and molecules obey the same quantum laws of superposition as qubits. Companies also want artificial intelligence experts to start using their computers. Because quantum computers obey different mathematical rules, they should be able to identify different patterns in data sets, says physicist Maria Schuld of Xanadu.

Last month Xanadu released PennyLane, a software package meant to make it easier to run machine learning algorithms on a quantum computer. Besides, the hardware is far from complete, says Schuld. It has a symbiotic relationship with its software: hardware experts can adapt their machine designs to better suit the algorithms with the most potential. At the same time, the limitations of the hardware inform how software developers build their tools. To encourage people to use the code, IBM and Xanadu also run contests for the best projects that use their tools.
