Quantum Computation

A set of quantum gates G (also called a basis) is said to be universal for quantum computation if any unitary operator can be approximated with arbitrary precision by a circuit involving only those gates (called a G-circuit). Since complex numbers do not help in quantum computation, we also call a set of real gates universal if it approximates arbitrary real orthogonal operators. Which set of gates are universal for quantum computation? This basic question is important both in understanding the power of quantum computing and in the physical implementations of quantum computers, and has been studied extensively. Examples of universal bases are: (1) Toffoli, Hadamard, and π 4 -gate, due to Kitaev [5] (2) CNOT, Hadamard, and π 8 -gate, due to Boykin, Mor, Pulver, Roychowdhury, and Vatan [2], and (3) CNOT plus the set of all single-qubit gate, due to Barenco, Bennett, Cleve, DiVincenzo, Margolus, Shor, Sleator, Smolin, and Weinfurter. Here is an explanation video about Universal Quantum

The Eiffel Tower

The Eiffel Tower (French: Tour Eiffel) is an iron tower built on the Champ de Mars on the banks of the River Seine in Paris. The tower has become a global icon of France and one of the world famous structure. The structure was built between 1887 and 1889 as the entrance Exposition Universelle, a World's Fair celebrated the French Revolution a century. Eiffel originally planned to build the tower in Baecelona, ​​for the Universal Exposition of 1888, but the responsible parties in Barcelona city hall thought strange and expensive, and does not fit the city. After the rejection of Plan Barcelona, ​​Eiffel send the draft to those responsible for the Universal Exhibition in Paris, where he built the tower a year later, in 1889. The tower was inaugurated on March 31, 1889, and opened on 6 May. Three hundred workers joined together 18,083 Embedded metal parts (a pure form of structural iron), using two and a half million nails, the structural form by Maurice Koechelin. The risk
