Google patents method to link quantum bits in a grid

Patent drawing
Patent drawing from the official filing.

Google describes a way to connect quantum bits arranged in a two-dimensional grid by pairing them up. The method performs linking operations on multiple pairs at the same time while adjusting the settings of specific bits to prevent unwanted interference.

Why it mattersThis technique helps manage the complex connections between quantum bits, which is a key challenge in building stable quantum computers.

In the filing’s own words

Methods, systems, and apparatus for performing an entangling operation on a system of qubits. In one aspect, a method includes operating the system of qubits, wherein the system of qubits comprises: a plurality of first qubits, a plurality of second qubits, a plurality of qubit couplers defining nearest neighbor interactions between the first qubits and second qubits, wherein the system of qubits is arranged as a two dimensional grid and each qubit of the multiple first qubits is coupled to multiple second qubits through respective qubit couplers, and wherein operating the system of qubits comprises: pairing multiple first qubits with respective neighboring second qubits; performing an entangling operation on each paired first and second qubit in parallel, comprising detuning each second qubit in the paired first and second qubits in parallel.

What exactly they claim (claim 1)

1. A method comprising: performing multiple entangling operations on a system of qubits, wherein the system of qubits comprises a plurality of first qubits and a plurality of second qubits, wherein each first qubit is selectively interactable with one or more second qubits, the performing comprising: pairing multiple first qubits with respective second qubits into multiple subsets of paired first and second qubits, the multiple subsets comprising overlapping subsets of paired first and second qubits, wherein each paired first and second qubit in a subset is nonadjacent to other paired first and second qubits in the subset, and for each subset of the multiple subsets, performing an entangling operation on each paired first and second qubit in the subset in parallel.
