Name	Description
integer(const Qbit qbit) -> integer	Returns the integer representation of the qubit state.
integer(const Fbit fbit) -> integer	Returns the integer representation of the fermionic product state.

integer(const Qbit qbit) -> integer

Returns the integer representation of the qubit state.

Given the product state $\vert s_0 s_1 ... s_{N-1} \rangle$, then the integer method returns $s_02^0 + s_12^1 + ... + s_{N-1}2^{N-1}$, where $N$ is the number of sites.

Example

Qbit("0011").integer() // Returns (2**2 + 2**3) = 12

integer(const Fbit fbit) -> integer

Returns the integer representation of the fermionic product state.

Given the product state $\verts_0 s_1 ... s_{N-1} \rangle$, then the get_representation method returns $s_02^0 + s_12^1 + ... + s_{N-1}2^{N-1}$, where $N$ is the number of sites.

Example

integer(Fbit("0011")) // Returns (2**2 + 2**3) = 12
