Abstract: As a new computing model, quantum computing can in principle exploit uantum mechanical ef
fects to perform computations more rapidly than classical Turing Machine model based on the principle of
quantum computing and me iman uantum Meanwhile, the physical implementations of quantum computer
are also proposed Optic photon quantum computer and quantum computer based on Nuclear Magnetic Reso
nance( NMR),ion traps or harmonic oscillator, ete., have been realized one by one, Several quantum algorithms
appear in recent years. A successful demonstration of Shors quantum algorithm is made by using a quantum
computing device based on NMR in 2001, and it shows the quantum computers great potentia power for
processing complieated problems. Finally, the developments in the aspeel of physical implementatie
quantum
computer are summarized
Key words quantum computing quantum compuer quantum algorithm; architecture of quantum computer
