I very firmly think no (probability <1%), but I'm not going to bet, for keynesian beauty contest reasons
The NSA allows the "Advanced Encryption Standard (AES), per FIPS 197, using 256 bit keys to protect up to TOP SECRET" data. (Potentially decades or longer until declassification.) It's believed to be quantum resistant.
