Google says it has reached a milestone known as quantum supremacy, here are the quantum computing milestones that led to this point.

1980 – Paul Benioff describes the first quantum mechanical model of a computer, showing that quantum computers are theoretically possible.

1985 – David Deutsch develops the idea of a universal quantum computer: a way to mathematically understand what is possible on a quantum computer.

1994 – Peter Shor develops “Shor’s algorithm”, which would allow a quantum computer to factor large numbers much faster than the …
