Symmetric placement of components on a chip to reduce crosstalk induced by chip modes

摘要

A method and system to control crosstalk among qubits on a chip are described. The method includes placing two or more components symmetrically on the chip, the chip including the qubits, and driving two or more ports symmetrically to control the crosstalk based on controlling coupling of chip mode frequencies and qubit frequencies.

1. A method to control crosstalk among qubits on a chip, the method comprising:
placing two or more components symmetrically on the chip, the two or more components including the qubits and two or more ports; driving the two or more ports symmetrically, using corresponding two or more drive signals, to control the crosstalk based on controlling coupling of chip mode frequencies and qubit frequencies, the driving symmetrically including each of the two or more drive signals including a same bias as and either a same phase as or a phase 180 degrees different than a phase of one or more other ones of the two or more drive signals.
