The method addresses a weakness that bedevils performance of the next-generation computers by suppressing erroneous calculations while increasing fidelity of results, a critical step before the machines can outperform classic computers as intended.
The technique administers staccato bursts of tiny, focused energy pulses to offset ambient disturbances that muck sensitive computations.
Lidar is the Viterbi Professor of Engineering at USC and corresponding author of the study; he led a team of researchers at CQIST, which is a collaboration between the USC Viterbi School of Engineering and the USC Dornsife School of Letters, Arts and Sciences.
Quantum computers are fast, but fragile
Quantum computers have the potential to render obsolete today's super computers and propel breakthroughs in medicine, finance and defense capabilities.
They harness the speed and behavior of atoms, which function radically different than silicon computer chips, to perform seemingly impossible calculations.
