+## QuBit
 
+QuBit(alpha: complexe, beta: complexe)
+
+- alpha: complexe value for |0>
+- beta: complexe value for |1>
+
+### Attributes
+
+- ```__state: list[complexe]```
+
+  list of the values for the state |0> and |1>
+
+- ```__intricated: bool```
+
+  tells if the qubit is intricated or not
+
+### Methode
+
+- ```__init__(alpha: complexe=1, beta: complexe=0) -> None```
+
+  initiates the qubit
+
+- ```is_intricated() -> bool```
+
+  returns the value of __intricated
+
+- ```get_MuBit() -> None```
+
+  returns the MuBit in wich the QuBit is intricated. If not intricated, rerurns None
+
+- ```__str__() -> str```
+
+  returns a string representation of the list of __state
+
+- ```__apply(m: Matrix) -> None```
+
+  takes a Matrix and modifies the QuBit according the matrix
+
+- ```observe() -> list[int]```
+
+  forces the QuBit in a state, where the probabilities are given throught __state. Returns the new __state obtained.
