As it stands, IBM’s largest quantum computer has five qubits. By contrast the average laptop has hundreds of millions of bits in its processors, although the two types of computers are not directly comparable. IBM hopes, however, to continue its research with the aim of building quantum computers with roughly 50 qubits. For comparison, an IBM spokesperson told Quartz, you can simulate the computational power of a 25-qubit quantum computer on a regular laptop. At about 45 qubits, you’d need the world’s fastest supercomputers, and above 50, “you couldn’t build large enough classical computing systems to simulate that size of a quantum system.”

In IBM’s vision of the future, quantum computers could be used for discovering new drugs, securing the internet, modeling the economy, or potentially even building far more powerful artificial intelligence systems—all sorts of exceedingly complicated tasks. One area the company is looking at right now is in chemistry, attempting to simulate what’s going on in a molecule. “Even for simple molecules like caffeine, the number of quantum states in the molecule can be astoundingly large,” the spokesperson said, “so large that all the conventional computing memory and processing power scientists could ever build could not handle the problem.”

When Quartz visited IBM’s quantum computing lab in Yorktown Heights in 2015, the work being done was viewed as fundamental—research for the sake of research—rather than anything tied to specific business goals. But then again, so was the research that has since led to the creation of Watson. Originally conceived of to take on the question-as-answers gameshow of Jeopardy!, which researchers saw as a “unique and compelling AI question,” Watson has become a set of machine-learning and AI services that IBM sells, and intends to invest $1 billion into.

As IBM’s core businesses of cloud services and data management have failed to kickstart growth—the company has experienced 19 consecutive quarters of falling revenue—it’s having to open itself up to different possibilities. Watson has yet to reverse IBM’s negative trend, although CEO Ginni Rometty recently said that 1 billion people will interact with Watson in some capacity this year.

It remains to be seen whether quantum computing is ready for prime time. But if IBM is able to crack it, the results could be as important as any of the moonshots IBM has achieved over its 100-plus years of existence.
