John Preskill Explains ‘Quantum Supremacy’
Researchers finally seem to have a quantum computer that can outperform a classical computer. But what does that really mean?
My debut column for
is about quantum supremacy.
Precisely controlling a quantum computer is notoriously difficult. That’s why, as Caltech physicist John Preskill explains, Google’s work possibly achieving quantum supremacy is an important next step, even if may not yield practical applications.
Thoughts on quantum supremacy from John Preskill
) and Scott Aaronson (
). Couldn’t imagine better guides through the thickets of quantum computation.
"The words 'quantum supremacy' ... through its association with white supremacy, evokes a repugnant political stance."
In 2012, John
coined the term "quantum supremacy." But why did he use that phrase? And—now that a team at Google has claimed to achieve it—what's next in quantum computing? John explains, via
