dqc_simulator.software.dqc_circuit

Defining a convenience class for encapsulating meta info on DQC circuits.

class dqc_simulator.software.dqc_circuit.DqcCircuit(qregs, cregs, native_gates, ops, qreg2node_lookup=None, circuit_type=None)

Bases: object

Convenience class for encapsulating meta info on DQC circuits

Parameters

qregsdict of dicts

The quantum registers and their associated info. Subdicts should have the keys ‘size’, and ‘starting_index’, and integer values for each.

cregsdict

The classical registers and their associated sizes.

native_gatesdict

The gates native to the processor upon which the DQC circuit will be enacted.

opslist of lists

The operations (such as gates, initialisations or measurements) in the quantum circuit written in a way dqc_simulator can understand.

qreg2node_lookupdict or None, optional

A mapping from qreg names to node names. This can be used to specify the partitioning of the circuit manually by associating each qreg with an appropriate node name

circuit_typestr or None, optional

Meta info indicating what is left to do to the circuit

Can be ‘monolithic’, ‘unpartitioned’ ‘prepped4partitioning’, or ‘partitioned’. TO DO: add more options like ‘optimised’.

add_scheme_to_2_qubit_gates(scheme)

Specifies the scheme to be used for all two qubit gates.

Parameters

scheme (str) – The scheme to be used for all remote two-qubit gates

lock_in_gate_specs()

Renders all elements of self.ops immutable. This is useful for protecting against accidental alteration of elements in self.ops.

replace_qreg_names(node_0_name='placeholder', node_1_name='placeholder')

Replaces node names in each gate_spec in ops with a placeholder indicating that partitioning should be done

Parameters

node_1_namestr, optional

The word to use for the first node in each gate_spec or an appropriate_placeholder
