In 1996, a rundown of criteria that are mandatory
for building up a quantum computer anticipated by the physicist David P.
DiVincenzo in his paper “The Physical Implementation of Quantum
Computation” was distributed. It was called as the DiVincenzo’s criteria.



2009, the first solid-state quantum processor was created by a group of
researchers at Yale University. The chip was a two-qubit superconducting chip. It
had simulated atom qubits which consisted of a large number of atoms of aluminum.
These atoms were like a single atom which was able to occupy two states.


the University of Bristol a group of researchers created a silicon chip. Quantum optics
wasthe basis for the chip. The chip ran on the Shor’s algorithm. A journal
based on Quantum Information Processing was published by Springer.


February 2010, the Symmetric Functions ordered from various quantum gates were
used to develop combinational circuits like adder, subtractor etc.


April 2011, Australian and Japanese scientists made advancement in the field of
They were able to transfer a compound quantum data set. The integrity
of transmission was completely maintained, i.e. the superpositions of the
qubits were not affected at all.


September 2011, a proof was established that Von Neumann architecture could be
used to make quantum computers. The separation of RAM could be used for the


In May 2013, Quantum Artificial
Intelligence Lab was launched by Google and hosted by NASA’s Ames Research


2014, silicon was used as a protecting shell around qubits by the researchers
at University of New South Wales. This made the chips more precise and
increased the length of time they hold the information. Also, this made the
development of quantum computers easy.


October 2015, a quantum logic gate in silicon was built by researchers at University
of New South Wales.


August 2016, the first quantum computer that could be reprogrammed was built by
a group of researchers at the University of Maryland.


December 2017, a preview version of a “Quantum Development Kit” was
released by Microsoft. Q# is a programming dialect which can be utilized to
compose programs that are run on a quantum computer.
