Method of Qbit.
Overloads
| Name | Description |
|---|---|
count() -> integer | Returns the sum of the qubit states (interpreted as integers) in the product state. |
count(const List<integer> sites) -> integer | Returns the sum of the qubit states on a subset of indices (interpreted as integers) in the product state. |
count() -> integer
Returns the sum of the qubit states (interpreted as integers) in the product state.
Example
Qbit("10010001").count() // Returns 3
count(const List<integer> sites) -> integer
Returns the sum of the qubit states on a subset of indices (interpreted as integers) in the product state.
Parameters
- sites: The subset of sites that are used to compute the sum.
Example
Qbit("10010001").count([0,1,2,3]) // Returns 2
