get_num_packed_integers#

cuquantum.pauliprop.experimental.get_num_packed_integers(int32_t num_qubits) → int32_t[source]#

Returns the number of packed integers of cupaulipropPackedIntegerType_t needed to represent the X bits (or equivalently, the Z bits) of a single Pauli string.

Parameters:

num_qubits (int32_t) – Number of qubits.

Returns:

Number of uint64 integers needed to store X bits (or: Z bits) for one Pauli string. To get the total storage requirement, multiply this value by 2.

Return type:

int32_t
