Researchers from the University of Cambridge found that quanta can remain inextricably linked
Quantum systems are built thanks to the specialparticle behavior at the atomic level: these systems can be used in computers to perform ultra-fast computations. Whereas a conventional computer bit is an electrical switch that can be set to one or zero, a quantum bit or qubit can be both one and zero at the same time.
However, qubits are extremely finicky, so the slightest noise in their environment can lead to rupture and entanglement, noted Dr. Showan Dutta of the Cambridge Cavendish Laboratory, the first author of the paper.
A group of researchers figured out how to solve thisproblem: they modeled an atomic system in the form of a lattice in which the atoms are close to each other. The authors found that if the noise did not affect the particles on the left and right sides. This amazing property was achieved thanks to a special type of symmetry that keeps all pairs together.
This discovery, the researchers believe, will form the basis of ultrafast quantum computers.
