The point at which quantum computers will be capable of breaking existing cryptographic algorithms — known as “Q-Day” — is approaching. It’s a juncture that’s been discussed for years, but with advancements in computing power, post-quantum threats are becoming very real. Some security experts believe Q-Day will occur within the next decade, potentially leaving all digital information vulnerable under current encryption protocols.
Post-quantum cryptography (PQC) is therefore high on the agenda as the security community works to understand, build, and implement cryptographic encryption that can withstand post-quantum threats and attacks of the future.
