Preskill connects the theory of reliable quantum computation with a practical question: what can a noisy machine accomplish, and what would it take to protect a useful calculation?

Preskill’s work links methods for protecting quantum information with a framework for reading the field’s promises. With Daniel Gottesman and Alexei Kitaev, he introduced an oscillator encoding that protects against small displacement errors. His NISQ-era analysis examines opportunities and limitations before comprehensive error correction is available. Together, these contributions explain why physical-qubit counts alone cannot tell a reader whether a machine can perform a reliable calculation. His current Caltech curriculum vitae also lists a Senior Scientist role at Oratomic beginning in 2026, alongside his academic appointments. That concurrent affiliation provides context for reading company forecasts; the underlying research and its assumptions remain the evidence to examine.
