The path-integral formulation of the Postquantum theory of classical gravity is now in Physical Review X! Other results from our group have been published at the same time, so this is a good opportunity to review progress. ⚛️ 🧪https://superposer.substack.com/p/postquantum-gravity-new-results-and 1/2
Postquantum gravity: new results and the state of play (I)
A covariant path-integral formulation of the Postquantum theory of classical gravity (PQG) has just been published in Physical Review X, and a few other related papers have come at the same time.

Inspired by your Apr blogpost, I threw together isitpostquantum.com to check for postquantum KEX on high value domains and document if/when they’ve transitioned to X25519MLKEM768
Is it postquantum?
