OpenSSL Position and Plans on Private Key Formats for Post-Quantum Algorithms

The anticipated future arrival of cryptographically relevant quantum computers (CRQCs), that could undermine the algorithms that underlie the currently most widely used public key algorithms (ECDHE, ECDSA, DH and RSA), has led to the development and recent standardisation of new “post-quantum” (PQ) algorithms, that are believed to not be vulnerable to CRQC attack.

The case against Google's claims of "quantum supremacy"
(wordpress.com)
The 2019 paper “Quantum supremacy using a programmable superconducting processor” asserted that Google’s Sycamore quantum computer, with 53 qubits and a depth of 20, performed a specific computation in about 200 seconds. According to Google’s estimate, a state-of-the-art classical supercomputer would require approximately 10,000 years to complete the same computation.
