What Is Quantum As A Service And Why Does It Matter For Your Business

Quantum computing is generating a lot of excitement in the tech world right now. Following several recent breakthroughs, this once theoretical technology is increasingly accessible to researchers and even businesses.

Just in case you’re still not sure—quantum computing refers to a new generation of processing technology that, by harnessing the strange properties of quantum mechanics, can perform certain mathematical functions millions of times faster than even the most powerful current supercomputers.

As you might expect of devices that often need to be super-cooled to close to absolute zero to work, current quantum computers are hugely expensive to own and difficult to maintain.

This is where quantum-as-a-service comes in. Thanks to QaaS, businesses wanting to experiment with it or even start putting it to operational use don’t need to spend millions of dollars on hardware and a dedicated facility to operate it from.

Instead, QaaS providers let businesses or research organizations access their quantum computers through the cloud, using a pay-as-you-go model to minimize initial overheads.

The global market for quantum computing is expected to grow from $1.8 billion in 2025 to close to $7.5 billion by 2030. QaaS is likely to play an important role in enabling this growth, and benefits are expected in many fields, including drug discovery and understanding climate change.
