In October 2019, Google announced its 53-qubit quantum computer named Sycamore had achieved ‘quantum supremacy.’

That’s when quantum computers can complete tasks exponentially more quickly than their classical counterparts.

In this case, Google said its quantum machine completed a task in 200 seconds that would have taken the world’s most powerful computer 10,000 years to complete. IBM, another major player in quantum computing, took issue with the findings.

Either way, it was a big milestone in quantum computing, and it’s leading to a lot of hype in the field. Here’s how quantum computing works, and how it could change everything from Wall Street to Big Pharma and beyond.

CNBC explores the rise of open source software and how it went from fringe movement to mainstream and core to the every enterprise.

Open-source software powers nearly all the world’s major companies. This software is freely available, and is developed collaboratively, maintained by a broad network that includes everyone from unpaid volunteers to employees at competing tech companies. Here’s how giving away software for free has proven to be a viable business model.
