How to Optimize the Structure and Quality of Thin Film Nobium for Superconducting Circuits

The performance of superconducting microwave circuits is strongly influenced by the material properties of the superconducting film and substrate. While progress has been made in understanding the importance of surface preparation and the effect of surface oxides, the complex effect of superconductor film structure on microwave losses is not yet fully understood. In this study, …

IonQ Has 29 Algorithmic Qubit Quantum Computer

IONQ met their technical target of 29 algorithmic qubits (#AQ) seven months earlier than expected. IonQ Forte is their newest quantum system. IonQ Forte represents a 16x step up in power from the IonQ Aria system. IonQ’s qubits are trapped ionized ytterbium atoms, a silvery rare-earth metal. Each ytterbium atom is perfectly identical to every …
