## 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.
|
|
|
|
|
