Washington:
Future computers will perform complex calculations unthinkable for
existing models with scientists tweaking a mechanism to process
and transmit data at phenomenally high speeds.
Future computers will exploit the mind-bending properties of
quantum particles, a mode of computing that relies on quantum bits
or qubits, encoding information as ones and zeros.
While a bit can represent either a one or a zero, a qubit can
represent both one and zero simultaneously, a state known as
superposition.
This allows for instantaneous processing of calculations in a
truly parallel system, skyrocketing computing ability, the journal
Nature magazine reports.
Using intense magnetic fields, Susumu Takahashi, assistant
professor at the University of Southern California's Dornsife
College and colleagues managed to suppress decoherence, a key
stumbling block in quantum computing.
Decoherence, described as a "quantum bug," knocks quantum particle
out of superposition, the ability to exist simultaneously in one
and zero states, which has delayed the creation of a fully
functional quantum computer, says a Southern California release.
Researchers figured out that qubits function optimally when
decoherence is reduced by 1,000 times, something which crystalline
molecular magnets helped Takahashi accomplish.
"This will obviously increase signals from the qubit drastically,
so the detection of the qubit in the molecular magnets is much
easier," Takahashi said.
