Nanodiamond Levitated in Free Space with Lasers Could Further Quantum Computing

You could do the same thing with twisted carbyne picotube macramé....

So what would happen to computing speeds if programmers wrote the code based on coding and process efficiency instead?

There's a priceless bit at the end of the article;

When Gizmag asked Vamivakas about how far he thought we were from reliable quantum computing, he said, "I don't really like to comment on how far or close quantum computing is. There is a lot of great progress being made in a variety of systems towards this goal. In fact recently there have been some remarkable achievements regarding quantum simulation - using one quantum system to simulate another - and the idea of quantum simulation crystallized around the same time as a quantum computer."

That roughly translates as, 'I haven't got a clue'.

I'd suspect that Vamivakas knows full well that it boils down to somebody getting lucky in the lab one day. Hyping it to Gizmag will keep the funding going. Working on an Apple Frog might generate more funding.
