A new ion trap for larger quantum computers

https://phys.org/news/2024-03-ion-larger-quantum.html

"static traps with additional magnetic field, called Penning traps, enable both arbitrary transport and necessary operations for quantum computers... superconducting magnet (3 Tesla) and chip with several electrodes, cryogenically cooled mirrors... channel laser through magnet to ions... single trapped ion can be moved arbitrarily on chip by controlling different electrodes... many traps packed onto single chip... future: trap 2 ions in neighboring Penning traps on same chip demonstrating operations with several qubits"
