Abstract
An analog processor, for example a quantum processor may include a plurality of elongated qubits that are disposed with respect to one another such that each qubit may selectively be directly coupled to each of the other qubits via a single coupling device. Such may provide a fully interconnected topology.

An analog processor system comprising:
- a plurality of quantum devices forming a fully interconnected topology of at least 5 quantum devices;
- and
- a plurality of controllable coupling devices wherein there exists a controllable coupling device between each pair of quantum devices in the plurality of quantum devices.
An analog processor system, comprising:
- a plurality of qubit devices;
- and
- a plurality of coupling devices, where at least one of the qubit devices is selectively directly coupleable to each of at least nine of the other qubit devices by respective single ones of the coupling devices.
An analog processor, comprising:
- a plurality of qubit devices, each of the qubit devices having an elongated loop of superconducting material interrupted by at least one Josephson junction;
- and
- a plurality of coupling devices, each of the coupling devices operable to selectively couple a respective pair of the qubit devices, where at least one of the qubit devices is selectively directly coupleable to each of at least five nearest neighbor qubit devices as measured in a two dimensional plan view of the qubit devices by a respective single one of the coupling devices.
