qat.devices

Predefined devices

The qat.devices module contains the topologies of various superconduction quantum processors. The following architectures are available:

`qat.devices.GOOGLE_SYCAMORE`	Topology of Google Sycamore
`qat.devices.IBM_BURLINGTON`	Topology of IBM Burlington
`qat.devices.IBM_JOHANNESBURG`	Topology of IBM Johannesburg
`qat.devices.IBM_MELBOURNE`	Topology of IBM Melbourne
`qat.devices.IBM_RUESCHLIKON`	Topology of IBM Rueschlikon
`qat.devices.IBM_SINGAPORE`	Topology of IBM Singapore
`qat.devices.IBM_TOKYO`	Topology of IBM Tokyo
`qat.devices.IBM_YORKTOWN`	Topology of IBM Yorktown
`qat.devices.RIGETTI_AGAVE`	Topology of Rigetti Agave
`qat.devices.RIGETTI_ASPEN`	Topology of Rigetti Aspen
`qat.devices.ZUCHONGZHI`	Topology of Zuchongzhi chip

Each architecture is describes via a HardwareSpecs object. For instance, to access the connectivity of Rigetti’s Aspen chip:

from qat.devices import RIGETTI_ASPEN

print("Type:", type(RIGETTI_ASPEN).__name__)
print(RIGETTI_ASPEN)

Device generators

Additionally, the module also provides generators for regular topologies:

`qat.devices.AllToAll`	A device with all-to-all connectivity
`qat.devices.GridDevice`	A device with a grid connectivity
`qat.devices.LineDevice`	A device with a Linear Nearest Neighbor (LNN) connectivity
`qat.devices.SquareGridDevice`	A device with a square grid connectivity
