Have you seen this article?

Apparently, there's a team at MIT that's looking at a way to overcome the two-qubit gate problem by drastically reducing error rates. Here's what the team has said:
“We have now taken the tunable coupler concept further and demonstrated near 99.9 percent fidelity for the two major types of two-qubit gates, known as Controlled-Z gates and iSWAP gates. Higher-fidelity gates increase the number of operations one can perform, and more operations translates to implementing more sophisticated algorithms at larger scales.”
This is a major step on the path to more accessible, practical quantum computers. Is anyone here familiar with the other problems that quantum computing faces?
