From Wikipedia, the free encyclopedia

This is a timeline of quantum computing.

1960s[edit]

1968[edit]

1970s[edit]

1970[edit]

1973[edit]

1975[edit]

  • R. P. Poplavskii published "Thermodynamical models of information processing" (in Russian)[4] which showed the computational infeasibility of simulating quantum systems on classical computers, due to the superposition principle.

1976[edit]

  • Roman Stanisław Ingarden, a Polish mathematical physicist, published the paper "Quantum Information Theory" in Reports on Mathematical Physics, vol. 10, 43–72, 1976 (The paper was submitted in 1975). It is one of the first attempts at creating a quantum information theory, showing that Shannon information theory cannot directly be generalized to the quantum case, but rather that it is possible to construct a quantum information theory, which is a generalization of Shannon's theory, within the formalism of a generalized quantum mechanics of open systems and a generalized concept of observables (the so-called semi-observables).

1980s[edit]

1980[edit]

  • Paul Benioff described the first quantum mechanical model of a computer. In this work, Benioff showed that a computer could operate under the laws of quantum mechanics by describing a Schrödinger equation description of Turing machines, laying a foundation for further work in quantum computing. The paper[5] was submitted in June 1979 and published in April 1980.
  • Yuri Manin briefly motivated the idea of quantum computing.[6]
  • Tommaso Toffoli introduced the reversible Toffoli gate,[7] which (together with initialized ancilla bits) is functionally complete for reversible classical computation.

1981[edit]

  • At the first Conference on the Physics of Computation, held at the Massachusetts Institute of Technology (MIT) in May,[8] Paul Benioff and Richard Feynman gave talks on quantum computing. Benioff's built on his earlier 1980 work showing that a computer can operate under the laws of quantum mechanics. The talk was titled “Quantum mechanical Hamiltonian models of discrete processes that erase their own histories: application to Turing machines”.[9] In Feynman's talk, he observed that it appeared to be impossible to efficiently simulate an evolution of a quantum system on a classical computer, and he proposed a basic model for a quantum computer.[10]

1982[edit]

1984[edit]

1985[edit]

1988[edit]

  • Yoshihisa Yamamoto and K. Igeta proposed the first physical realization of a quantum computer, including Feynman's CNOT gate.[16] Their approach uses atoms and photons and is the progenitor of modern quantum computing and networking protocols using photons to transmit qubits and atoms to perform two-qubit operations.

1989[edit]

1990s[edit]

1991[edit]

1992[edit]

  • David Deutsch and Richard Jozsa proposed a computational problem that can be solved efficiently with the deterministic Deutsch–Jozsa algorithm on a quantum computer, but for which no deterministic classical algorithm is possible. This was perhaps the earliest result in the computational complexity of quantum computers, proving that they were capable of performing some well-defined computational task more efficiently than any classical computer.
  • Ethan Bernstein and Umesh Vazirani propose the Bernstein–Vazirani algorithm, It is a restricted version of the Deutsch–Jozsa algorithm where instead of distinguishing between two different classes of functions, it tries to learn a string encoded in a function. The Bernstein–Vazirani algorithm was designed to prove an oracle separation between complexity classes BQP and BPP.

  • Samuel L. Braunstein and collaborators showed that none of the bulk NMR experiments performed to date contained any entanglement; the quantum states being too strongly mixed. This is seen as evidence that NMR computers would likely not yield a benefit over classical computers. It remains an open question, however, whether entanglement is necessary for quantum computational speedup.[35]

  • Emanuel Knill, Raymond Laflamme, and Gerard Milburn showed that optical quantum computing is possible with single-photon sources, linear optical elements, and single-photon detectors, establishing the field of linear optical quantum computing.
