cuquantum.custatevec.collapse_on_z_basis(intptr_t handle, intptr_t sv, int sv_data_type, uint32_t n_index_bits, int32_t parity, basis_bits, uint32_t n_basis_bits, double norm)[source]

Collapse the statevector on the given Z product basis.

  • handle (intptr_t) – The library handle.

  • sv (intptr_t) – The pointer address (as Python int) to the statevector (on device).

  • sv_data_type (cuquantum.cudaDataType) – The data type of the statevector.

  • n_index_bits (uint32_t) – The number of index bits.

  • parity (int32_t) – The parity, 0 or 1.

  • basis_bits

    A host array of Z-basis index bits. It can be

    • an int as the pointer address to the array

    • a Python sequence of index bits

  • n_basis_bits (uint32_t) – the number of basis bits.

  • norm (double) – The normalization factor for the statevector after collapse.
