London, July 21 (ANI): Scientists at the University of Southern California have made a breakthrough in the development of Quantum computers, which will use quantum mechanics to revolutionize the way information is processed.
Quantum computers will capitalize on the mind-bending properties of quantum particles to perform complex calculations that are impossible for today's traditional computers.
Using high magnetic fields, Susumu Takahashi, assistant professor in the USC Dornsife College of Letters, Arts and Sciences, and his colleagues managed to suppress decoherence, which is one of the key stumbling blocks in quantum computing.
"High magnetic fields reduce the level of the noises in the surroundings, so they can constrain decoherence very efficiently," Takahashi stated.
Decoherence has been described as a "quantum bug" that destroys fundamental properties that quantum computers would rely on.
Think of decoherence as a form of noise or interference, knocking a quantum particle out of superposition - robbing it of that special property that makes it so useful.
If a quantum computer relies on a quantum particle's ability to be both here and there, then decoherence is the frustrating phenomenon that causes a quantum particle to be either here or there.
"For the first time we've been able to predict and control all the environmental decoherence mechanisms in a very complex system - in this case a large magnetic molecule," said Phil Stamp, UBC professor of physics and astronomy.
This research will appear in the online version of Nature magazine on June 20. (ANI)
