7 commentsYou can maybe squint at their “sequence fidelity” and extract some information about this.
Anyone could provide some context on why this is significant and currently #3 on the front page?
* Fidelity
* Qubit count
* Coherence time
Without a roadmap to some goal this is just random PR. What's the path to convergence of fidelity of volume qubits for sustained periods to achieve calculations?
It is cool to achieve 99.9 2q fidelity... this is vitally important. And high coherence time is also important.
But you have to achieve "at least" this performance across all connected qubits, with 10's or 100's of qubits on chip, and get tolerant state prep and readout btw, while trying to perform useful quantum computing operations. The difference between this and what IQM announced is VASTLY different.
