Quantum technology could outperform conventional computers on some advanced optimization and computational tasks. In recent years, physicists have been working to identify new strategies to create quantum systems and promising qubits (i.e., basic units of information in quantum computers).
Researchers at the Institute for Complex Systems of CNR (Consiglio Nazionale delle Ricerche), Max Planck Institute for Chemical Physics of Solids, and other institutes worldwide have recently introduced a new superconducting and capacitively shunted qubit, which they dubbed "flowermon." This qubit, introduced in Physical Review Letters, is based on twisted cuprate van der Waals heterostructures.
"The project came about by a nice chance, during an attempt to combine the languages of our different expertise in conversation," Uri Vool, co-author of the paper, told Phys.org. "The initial motivation was the recent work of our collaborator Nicola Poccia, who was able to achieve a 'twisted van der Waals heterostructure' where they can control the angle between individual layers in the novel cuprate superconductor BSCCO without ruining its unique properties.
