qat.purr.backends.echo module

class Connectivity(value)

Bases: Enum

An enumeration.

Ring = 1

class EchoEngine(model=None, startup_engine=True, max_instruction_len=200000)

Bases: QuantumExecutionEngine

A target machine that just returns default values. Primarily used for testing and no-backend situations.

optimize(instructions): Runs optimization passes specific to this hardware.

run_calibrations(qubits_to_calibrate=None)

add_direction_couplings_to_hardware(model, connectivity)

apply_setup_to_hardware(hw, qubit_count=4, connectivity=None): Apply the default echo hardware setup to the passed-in hardware.

generate_connectivity(con_type, qubit_count)

get_default_echo_hardware(qubit_count=4, connectivity=None)

Generate a default echo target optionally providing the type of connectivity. Either you pass a pre-defined connectivity as defined in the Connectivity enum or a specific connectivity list of which qubits connect to which.

Return type:: QuantumHardwareModel
