The pace of progress in the field has picked up dramatically, especially in the past two years or so, along several fronts. Teams in academic laboratories, as well as companies ranging from small start-ups to large technology corporations, have drastically reduced the size of errors that notoriously fickle quantum devices tend to produce, by improving both the manufacturing of quantum devices and the techniques used to control them. Meanwhile, theorists better understand how to use quantum devices more efficiently.
“At this point, I am much more certain that quantum computation will be realized, and that the timeline is much shorter than people thought,” says Dorit Aharonov, a computer scientist at Hebrew University in Jerusalem. “We’ve entered a new era.”
