Introduction
A single virus particle is in and of itself essentially inert. It lacks needed components that cells have to reproduce. Viruses are intracellular obligate parasites which mean that they cannot reproduce or express their genes without the help of a living cell. The exact nature of what happens after the host is infected varies depending on the nature of the virus.
One of steps in virus replication is DNA replication.DNA has a quantum nature [1].
There is growing thought among physics [2], [3], [4] and biologists [5] that quantum mechanics might play an important role in living systems.
We have studied the mechanism of infected a cell by virus from a quantum point of view. We simulate steps in virus replication by quantum gates too.
Results
A bit is the fundamental concept of classical computing and classical information.
Quantum computing and quantum information are built upon a similar concept, the quantum bit, or qubit. A classical bit has a state (0 or 1), while a qubit [6], which correspond to the states for a bit. 1 and 0 can have two states
The difference between bits and qubits is that a qubit can be in a state, and it can also form linear combinations of states, often called superpositions[7]:
Ψ = a 0 + b 1
Numbers a and b are complex numbers, although they can be considered real numbers.
In other words, the state of a qubit is a vector in a complex, two-dimension vector space.

In this paper, we showed viruses can considered as a quantum system also we have discussed about steps of infected a cell by virus on the quantum mechanic.
