Rigetti Funded Research Yields High-fidelity, Coherence-limited Sweet Spot. Research funded by quantum computer leader Rigetti has demonstrated a high-fidelity, coherence-limited, parametrically-activated, two-qubit gate on a multi-qubit architecture having direct modulation of the tunable qubit.
The device involved was designed to work in a general purpose multi-qubit configuration – “it is not a one-off design exploiting favorable features that cannot be reproduced in larger lattices.” (It’s scalable, and handles white-noise well).
