John Preskill on Quantum Computing

John Preskill, Steven Hawking, Kip Thorne, Craig Cannon

Established by Richard Feynman's early theoretical work, the field of quantum computing has evolved from theoretical challenges in the 1970s to a practical reality enabled by mid-1990s error correction and recent hardware advancements in superconducting and trapped-ion systems. As current devices approach 100 qubits, they are poised to disrupt public-key cryptography through Shor's algorithm while simultaneously offering transformative capabilities in quantum chemistry simulation and materials science. The industry now focuses on bridging these applications through hybrid classical-quantum systems and developing post-quantum security measures to address the imminent threat to existing encryption standards.
