Q-Day—the moment when quantum computers can break widely used cryptography—may be approaching faster than expected due to recent algorithmic and hardware advances. Advances in algorithms and design are steadily lowering the bar for quantum attacks, even before large-scale hardware exists , while technology companies have begun deploying post-quantum cryptographic protections in hybrid modes , with some Big Tech firms accelerating their migration timelines while others maintain more cautious approaches.
