According to physicist Philippe Doumitrescu of the Flatirón Institute, this work is a completely new way of understanding the phase of matter.
The cubes that make up the quantum computer are easily confused and this leads to errors. To improve the reliability of the cubes, a multi-tactical approach is needed.
The symmetry can be one of the means to protect cubes from decoherence. If you turn the square by 90 degrees and you keep the same shape, this symmetry protects it.
If the cubes were affected by evenly distributed laser pulses, it ensured symmetry based on time rather than space, and the authors wanted to know whether they could enhance this effect by adding an asymmetric frequency and asymmetric quasiperiodicity.
This, in their theory, would provide not one temporal symmetry, but two, one actually hidden inside the other.
The idea was based on the earlier work of the team, in which the idea of creating something called a quasi-crystal came into play. It functions in time, not in space.
By comparison, the crystal consists of a symmetrical grid of atoms, which is repeated in space, but the structure of atoms on the quasi-crystal is not repeated, but is streamlined.
The team experimented on a commercial quantum computer developed by Quantinuum. They created a sequence of laser pulses based on Fibonacci numbers, where each segment is the sum of the previous two segments.
The team checked its work and sent lasers to an Itterbium Cube matrix, first in a symmetrical sequence and then in a quasi-period, and then measured the coherence of the two cubes at both ends of the trap.
For periodic sequence, the cubes were stable for 1.5 seconds. For quasi-periodic sequence, they remained stable for 5.5 seconds.
