AES has been observed to be very slightly leaky but not in a way that is practically exploitable, partly because even finding it is memory hard on a large volume of data. I know respected crypto experts that have been looking into this anomaly for a few years. It isn't out of the realm of possibility that there is a quantum shortcut related to that state leak.
