Researchers from the University of New South Wales in Sydney have increased the coherence of cubicles in quantum computers by a factor of 100, and the length of time they can store and process information has a significant impact on the performance of devices.
In quantum computations, the more rotations are kept in motion, the more likely it is that the information will be stored during computation, the scientists explain. When spinal cubes stop spinning, the calculation collapses, and the values processed by each block are lost.
In theory, researchers have estimated that coherence time can be increased by continuously spinning cubes; even simple rotation increases the storage time to 230 μms.
To make more progress, researchers have developed a complex cube management protocol. Instead of simply spinning atoms in circles, scientists rocked them from side to side, like the metronome. If each of these particles is supplemented by an individual electric field, it will cause them to lose resonance, but it will keep the overall rhythm of motion.
This technology significantly increases the time of coherence and also allows for the control of several cubes at the same time.
