Here is a lost of things Block stream has been working on re quantum:

@real_or_random proved post-quantum security of the Taproot commitment scheme (https://eprint.iacr.org/2025/1307.pdf), which is essential for a Taproot-based upgrade path (https://groups.google.com/g/bitcoindev/c/8O857bRSVV8/m/4cM-7pf4AgAJ)
@real_or_random discovered in 2018 that commit-reveal schemes (first discovered by @adam3us) could be applied to obtain post-quantum security (https://bitcoinops.org/en/newsletters/2025/04/04/#securely-proving-utxo-ownership-by-revealing-a-sha256-preimage). This is still the most compact signature scheme but it has other downsides. Variants appear from time to time on the ML.
Reviewed an earlier version of BIP 360, reported three vulnerabilities (https://groups.google.com/g/bitcoindev/c/oQKezDOc4us/m/I6tmPaA2AgAJ).
