Here is a brief timeline of the history of quantum computing.
1982: Richard Feynman discusses the potential advantages of a quantum computer.
1985: David Deutsch introduces the concept of a quantum computer.
1994: Peter Shor develops an algorithm for factoring large numbers on a quantum computer.
1996: Lov Grover develops an algorithm for searching unsorted databases on a quantum computer.
1999: D-Wave Systems, a company that today makes quantum computers, is founded by Gordie Rose.
2010: D-Wave Systems releases the first commercial quantum computer, the D-Wave One.
2019: Google claims to have reached quantum supremacy. Quantum Supremacy was termed by John Preskill in 2012 to describe when quantum systems could perform tasks surpassing those in the classical world.
