And while Rigetti has done an impressive job of fabricating its own transmon processors, it has still lagged behind its larger competitors. The qubit count in IBM's latest processors is over 60 ...

As quantum computing evolves from theory to commercialization, two distinct visions are emerging. Rigetti Computing RGTI and ...

The qubit count in IBM's latest processors is over 60, while Rigetti's latest is 31. Quantum computing companies know that they will have to work out ways to integrate qubits on more than one chip.

High-Fidelity, Frequency-Flexible Two-Qubit Fluxonium Gates with a Transmon Coupler. Physical Review X , 2023; 13 (3) DOI: 10.1103/PhysRevX.13.031035 Cite This Page : ...

And the company expects that this hybrid approach — and likely the 128-qubit machine that Rigetti plans to launch next year — will allow for running an algorithm that demonstrates quantum ...

Innsbruck physicists have presented a new architecture for improved quantum control of microwave resonators. In a study recently published in PRX Quantum, they show how a superconducting fluxonium ...

Another type of superconducting qubit, known as a fluxonium qubit, originated more recently. Fluxonium qubits have been shown to have longer lifespans, or coherence times, than transmon qubits.

The transmon qubit, one of the most widely used in the field for superconducting processors, typically has low anharmonicity. Anharmonicity is the difference between relevant transition ...

This NISQ era of quantum computing is also the age where multiple approaches to quantum emerge. It's akin to the moment before we decided to follow mostly through the x86 path. New research on ...
