intptr_t handle,
intptr_t view,
intptr_t trace_significand,
intptr_t trace_exponent,
intptr_t workspace,
intptr_t stream,
)[source]#

Computes the trace of the Pauli expansion view with the zero state, i.e. Tr(view * |0...0><0...0|).

Parameters:

  • handle (intptr_t) – Library handle.

  • view (intptr_t) – Pauli expansion view to be traced.

  • trace_significand (intptr_t) – Pointer to CPU-accessible memory where the trace’s significand will be written. The numerical type must match the data type of the views’ coefficients.

  • trace_exponent (intptr_t) – Pointer to CPU-accessible memory where the trace’s exponent will be stored. The numerical type is always double.

  • workspace (intptr_t) – Allocated workspace descriptor.

  • stream (intptr_t) – CUDA stream to be used for the operation.
