Bristlecone's native operation is the CZ, not CNOTs. However, you can transform between the two with Hadamard gates so this is sort of a trivial difference. Bristlecone can perform a CZ between any adjacent pair of qubits on a grid. You can see the grid by installing cirq and printing out the Bristlecone device: $ pip install cirq $ python >>> ...

From the original blog post presenting the Bristlecone quantum chip, here is the connectivity map of the chip: Each cross represent a qubit, with nearest-neighbour connectivity. If you number the qubits from left to right, top to bottom (just like how you read english), starting by $0$ then the connectivity map would be given by: connectivity_map = { i ...

The current version of PyQuil provides an "ISA" object that houses the information that you want about Rigetti's quantun processors, but it isn't formatted as you request. I'm a poor Python programmer, so you'll have to excuse my non-Pythonic-ness—but here's a snippet that will take a device_name and reformat the pyQuil ISA into one of your dictionaries: ...
