Caltech physicists have created the largest qubit array ever assembled: 6,100 neutral-atom qubits trapped in a grid by lasers. This milestone comes amid a rapidly growing race to scale up quantum computers. There are several approaches in development, including those based on superconducting circuits, trapped ions, and neutral atoms, as used in the new study. “This is an exciting moment for neutral-atom quantum computing,” says Manuel Endres, professor of physics at Caltech. “We can now see a pa

Flight has evolved four times in the history of life on Earth: in birds, bats, pterosaurs, and insects. The first three groups of animals evolved their wings from arms, making these wings straightforward to understand as other similar animals have analogous bones and musculature. Insect wings, however, have no muscles or nerves. They are instead controlled by muscles located inside the body that operate a system of marionette-like pulleys within a complex hinge at the base of the wing. Just how
