Systems, devices, and methods for analog processing

摘要

A system may include first and second qubits that cross one another and a first coupler having a perimeter that encompasses at least a part of the portions of the first and second qubits, the first coupler being operable to ferromagnetically or anti-ferromagnetically couple the first and the second qubits together. A multi-layered computer chip may include a first plurality N of qubits laid out in a first metal layer, a second plurality M of qubits laid out at least partially in a second metal layer that cross each of the qubits of the first plurality of qubits, and a first plurality N times M of coupling devices that at least partially encompasses an area where a respective pair of the qubits from the first and the second plurality of qubits cross each other.

1. A quantum processor comprising:
a plurality of unit cells tiled over an area such that each unit cell is positioned adjacent at least one other unit cell, each unit cell comprising:
a first set of qubits and a second set of qubits, wherein each qubit in the first set of qubits crosses at least one qubit in the second set of qubits; anda set of intra-cell coupling devices, wherein each intra-cell coupling device is positioned proximate a respective point where a qubit in the first set of qubits crosses a qubit in the second set of qubits and provides controllable communicative coupling between the qubit in the first set of qubits and the qubit in the second set of qubits; and the quantum processor further comprising:
a set of inter-cell coupling devices, wherein each inter-cell coupling device in the set of inter-cell coupling devices is positioned between a respective pair of qubits in adjacent unit cells and provides controllable communicative coupling between the respective pair of qubits in adjacent unit cells.
