Yes, for some definition of logical qubit. One of the first example is the experiment of Egan et al where they demonstrated a fault-tolerant QEC measurement using 13 physical qubits. https://arxiv.org/abs/2009.11482 They show improvements in the logical performance on the codes, but it is still a pretty small improvement (factor of 2). Another example is the experiment we performed at Google https://arxiv.org/abs/2207.06431 where we used superconducting qubits. In that experiment we showed that we were able to go from a small code to a slightly larger code and that the error got "slightly…

This is the paper: https://arxiv.org/abs/2009.11482 It's actually from last year, and other groups have done better experiments since then (in particular, experiments doing multiple rounds of correction instead of just immediately smashing the system and analyzing the pieces). It's quite funny to see a big deal being made of this paper now rather than a year ago.
