Amazon is now offering quantum computing as a service

Google and IBM may be battling for quantum supremacy, but Amazon is currently happy to be a middleman — today, it’s announcing and launching a preview of Amazon Braket, its attempt to turn the nascent field of quantum computing into a service you can access over the internet, a month after Microsoft did something similar. “Amazon Braket is a fully managed AWS service, with security & encryption baked in at each level,” the company explains in a blog post.

For now, it sounds like a pretty limited affair, where “you” will mean Amazon’s corporate customers, and where “service” means the ability to experiment by running simulations on a set of existing quantum computers from partners D-Wave, IonQ, and Rigetti. (IonQ is also a Microsoft Azure Quantum partner.)

“This new service is designed to let you get some hands-on experience with qubits and quantum circuits. You can build and test your circuits in a simulated environment and then run them on an actual quantum computer,” writes Amazon.

But Amazon says it’s also creating the “AWS Center for Quantum Computing,” a physical lab near the California Institute of Technology (Caltech) where it may research quantum computers of its own — and more uses for quantum computers, for that matter. The company’s director of quantum computing confirmed to Wired that Amazon is working on quantum hardware.

Theoretically, quantum computers could calculate far faster than traditional supercomputers thanks to the fact that their bits can exist in multiple quantum states instead of simply being on (1) or off (0), and that’s what Google recently claimed it had achieved with its 54-qubit Sycamore quantum computer. The company says its machine successfully made a calculation that would take the world’s most powerful supercomputer 10,000 years.

But quantum computers are also rare and extremely expensive, so Amazon and Microsoft are each attempting to turn them into a shared, managed, and potentially scalable resource, like Amazon already does with its highly valuable AWS cloud computing platform. That invisible server empire serves as backbone for many of the internet services you use today.

Update, 8:56 PM ET: I’d missed that Microsoft also announced a similar Azure Quantum service last month, and I’ve updated to mention it.
