(ComplexMatrix lhs [] const Fbit fbit) -> complex​

Array access operator with Fbit states.

Parameters​

  • fbit: A Fbit object whose integer representation is used to access a vector element.

Example​

var vec = vector([0,1,2,3])
vec[Fbit("01")] // Returns 2 (equivalent to vec[2])

(ComplexMatrix lhs [] const Qbit qbit) -> complex​

Array access operator with qubit product states.

Parameters​

  • qbit: A Qbit object whose integer representation is used to access a vector element.

Example​

var vec = vector([0,1,2,3])
vec[Qbit("01")] // Returns 2 (equivalent to vec[2])

(ComplexMatrix lhs [] const List<Fbit> states) -> complex​

Array access operator with fermionic states.

Parameters​

  • states: Vector of Fbit objects whose integer representation is used to access a matrix element.

Example​

var mat = matrix([[0,1,2],[3,4,5],[6,7,8]])
mat[[Fbit("00"), Fbit("01")]] // Returns 6 (equivalent to mat[0,2])

(ComplexMatrix lhs [] const List<Qbit> states) -> complex​

Array access operator with qubit product states.

Parameters​

mat[[Qbit("00"), Qbit("01")]] // Returns 6 + 0i (equivalent to mat[0,2])

(RealMatrix lhs [] const Fbit fbit) -> real​

Array access operator with Fbit states.

Parameters​
