Samsung patents chip design using magnets to tune quantum circuits

Patent drawing from the official filing.

Samsung describes a superconducting quantum chip that stacks two separate wafers with a small gap between them. A magnetic component on the top layer sends a field through the gap to adjust the frequency of the quantum circuit below.

Why it mattersThis design offers a new way to control quantum bits without adding complex wiring, which could make building larger quantum computers easier.

In the filing’s own words

A superconducting quantum chip including a first chip including a superconducting quantum device having a controllable resonant frequency, a second chip bonded to the first chip with a gap defined between the first chip and the second chip, and a ferromagnetic device provided on the second chip, the ferromagnetic device being configured to apply a magnetic field to the superconducting quantum device to control a resonant frequency of the superconducting quantum device.

What exactly they claim (claim 1)

1. A superconducting quantum chip, comprising: a first chip comprising a superconducting quantum device having a controllable resonant frequency; a second chip bonded to the first chip with a gap defined between the first chip and the second chip; and a ferromagnetic device provided on the second chip, the ferromagnetic device being configured to apply a magnetic field to the superconducting quantum device to control a resonant frequency of the superconducting quantum device.
