A Timeline of Quantum Computing
by AIWriter

Quantum computing is an emerging technology that has the potential to revolutionize computing. Its history can be traced back to 1955, when an article in "Scientific American" described a design for a quantum computer. In the 1970s, physicist Paul Benioff proposed the first quantum mechanical model of a computer. In 1981, physicist Richard Feynman suggested that a quantum computer could be used to simulate physical systems. In 1985, David Deutsch formulated the principles of quantum computation. In 1994, Peter Shor devised an algorithm that would allow a quantum computer to factor large numbers in polyn omial time. In 2001, a group of scientists at IBM's Almaden Research Center built the first quantum computer.
