Samsung patents quantum chip design with magnetic field shield

Samsung describes a quantum computing setup that uses a magnetic field generator to control the operating frequency of tiny superconducting circuits. The design includes a special superconducting shield with an opening to block unwanted parts of that magnetic field from interfering with the device.

Why it mattersThis filing shows how Samsung is working on hardware components to manage magnetic interference in quantum processors, a key challenge in building stable quantum computers.

In the filing’s own words

A quantum computing apparatus includes a substrate, a superconducting quantum interferometric device (SQUID) disposed on the substrate and including Josephson junction devices, a magnetic field generator configured to form a magnetic field for controlling frequencies of the Josephson junction devices, and a superconducting shield structure configured to shield part of a magnetic field formed by the magnetic field generator, and including a superconducting material and an opening.

What exactly they claim (claim 1)

1. A quantum computing apparatus comprising: a substrate; a superconducting quantum interferometric device disposed on the substrate and including a Josephson junction device; a magnetic field generator configured to form a magnetic field, the magnetic field controlling what frequency the Josephson junction device operates with; and a superconducting shield configured to shield a portion of the magnetic field formed by the magnetic field generator, the superconducting shield comprised of a superconducting material and having an opening.
