qoqo.operations.PragmaGetDensityMatrix
- class qoqo.operations.PragmaGetDensityMatrix
This PRAGMA measurement operation returns the density matrix of a quantum register.
- Parameters:
readout (string) – The name of the classical readout register.
circuit (Optional[Circuit]) – The measurement preparation Circuit, applied on a copy of the register before measurement.
- __init__()
