New analog quantum computers to solve previously unsolvable problems
Jan 2023, phys.org
To demonstrate the power of analog quantum computation using their new Quantum Simulator platform, the researchers first studied a simple circuit comprising two quantum components coupled together.The device simulates a model of two atoms coupled together by a peculiar quantum interaction. By tuning electrical voltages, the researchers were able to produce a new state of matter in which electrons appear to have only a 1/3 fraction of their usual electrical charge—so-called "Z3 parafermions." These elusive states have been proposed as a basis for future topological quantum computation, but never before created in the lab in an electronic device.
