It’s the holy grail of quantum computing: how to create the key building blocks known as quantum bits — qubits — that exist in a solid-state system at room temperature.
That problem may now be solved, according to scientists.
A group of Harvard scientists, led by Professor of Physics Mikhail Lukin and including graduate students Georg Kucsko and Peter Maurer and postdoctoral researcher Christian Latta, say they have cracked the problem, and they did it by turning to one of the purest materials on Earth: diamonds.Using a pair of impurities in ultra-pure, laboratory-grown diamonds, the researchers announced Tuesday that preliminary results show the ability to create quantum bits and store information in them for nearly two seconds, an increase of nearly six magnitudes.
