A Strange Phase of Matter Has Been Discovered

A new phase of matter was discovered in a quantum computer: during an experiment, physicists directed light at qubits using a scheme inspired by the Fibonacci sequence. According to physicist Philipp Dumitrescu of the Flatiron Institute, this work is a completely new way of understanding the phases of matter. The qubits that make up a quantum computer are easily entangled, and this leads to errors. A multi-tactic approach is needed to improve the reliability of qubits. Ensuring symmetry can be a mean of protecting qubits from decoherence. If you rotate the square by 90°, it will remain in the same shape. This symmetry works as a protection measure. If the qubits are exposed to uniformly distributed laser pulses, this provides a symmetry based not so much on space, but on time. The authors wanted to know if they could enhance this effect by adding not a symmetric periodicity, but an asymmetric quasi-periodicity. This, according to their theory, would provide not one temporal symmetry, but two. One is actually hidden inside the other.
