Microsoft Takes Path Less Traveled to Build a Quantum Computer

Software giant releases a quantum programming language and simulator, but still has no working computer

In the race to commercialize a new type of powerful computer, Microsoft Corp. has just pulled up to the starting line with a slick-looking set of wheels. There’s just one problem: it doesn't have an engine – at least not yet.

The Redmond, Washington-based tech giant is competing with Alphabet Inc.’s Google, International Business Machines Corp. and a clutch of small, specialized companies to develop quantum computers – machines that, in theory, will be many times more powerful than existing computers by bending the laws of physics.

Microsoft says it has a different approach that will make its technology less error-prone and more suitable for commercial use. If it works. On Monday, the company unveiled a new programming language called Q# – pronounced Q Sharp – and tools that help coders craft software for quantum computers. Microsoft is also releasing simulators that will let programmers test that software on a traditional desktop computer or through its Azure cloud-computing service.
