This short sales article from HPE (Hewlett Packard) is a bit more techie than we like, but does talk about a different type of qubit approach which removes lots of the 'noise' issues that we are learning are a blocker to commercial use. Therefore may be worth a 3 minute read.
IonQ takes a different approach. Its qubits are made using trapped ions, which are individual atoms, levitated in space with electrodes, controlled by laser beams. In this architecture, each qubit has the precision of an atomic clock, with quantum entangled superpositions that can, theoretically, persist indefinitely. Unlike systems based on the superconducting method, there are no physical wires linking IonQ’s qubits, and the programming is accomplished with laser beams that can be reconfigured to run any type of quantum computational circuit.
