Singular measurements
Singular measurements, i.e. a single measurement for a single qubit, are
represented through meas handles.
Constructing measurement objects
Measurement objects are constructed using dqcs_meas_new().
dqcs_meas_new()
Constructs a new measurement object.
Constructs a new measurement object.
dqcs_handle_t dqcs_meas_new(
dqcs_qubit_t qubit,
dqcs_measurement_t value
)
qubit must be set to the qubit that was measured, value must be set to
its value. The return value is the handle to the measurement object, or 0
if something went wrong.
Note that measurement objects implement the arb interface, so additional
data can be attached to the object.
They are also mutable after construction.
dqcs_meas_qubit_set()
Sets the qubit reference associated with a measurement object.
Sets the qubit reference associated with a measurement object.
dqcs_return_t dqcs_meas_qubit_set(
dqcs_handle_t meas,
dqcs_qubit_t qubit
)
dqcs_meas_value_set()
Sets the measurement value associated with a measurement object.
Sets the measurement value associated with a measurement object.
dqcs_return_t dqcs_meas_value_set(
dqcs_handle_t meas,
dqcs_measurement_t value
)
Attaching custom data
Measurement objects support the ArbData protocol for attaching custom data.
That is, all dqcs_arb_*() API calls can be applied to measurement handles.
Querying measurement objects
The measurement value and qubit reference can be queried from a measurement object as follows.
dqcs_meas_qubit_get()
Returns the qubit reference associated with a measurement object.
Returns the qubit reference associated with a measurement object.
dqcs_qubit_t dqcs_meas_qubit_get(dqcs_handle_t meas)
dqcs_meas_value_get()
Returns the measurement value associated with a measurement object.
Returns the measurement value associated with a measurement object.
dqcs_measurement_t dqcs_meas_value_get(dqcs_handle_t meas)
