Latest Patents

One of his latest patents is titled "Majorana pair based qubits for fault tolerant quantum computing architecture using superconducting gold surface states." This invention explores the concept of Majorana zero modes, which can separate in space under certain conditions. These modes are immune to decoherence from local noise sources, making them attractive for quantum computing applications. The patent discloses a metal-based heterostructure platform designed to produce these Majorana zero modes, utilizing the surface states of specific metals in combination with a ferromagnetic insulator and a superconductor. This innovative platform offers a robust energy scale and the potential for complex circuit designs through lithographic methods. The Majorana zero modes can be interrogated using planar tunnel junctions and electrostatic gates, allowing for selective tunneling into designated pairs of Majorana zero modes. The patent also provides examples of qubit designs and circuits particularly suitable for these metal-based heterostructures.

Another notable patent is the "Switchable superconducting Josephson junction device for low energy information storage and processing." This invention features a switchable Josephson junction that includes multiple ferromagnetic insulators defined by their respective magnetic alignments. The first superconducting layer is positioned between two ferromagnetic insulators, with its conductive state controlled by the relative magnetization orientation of the insulators. When the magnetizations are aligned in an antiparallel configuration, the first superconducting layer remains superconducting. However, it transitions to a normally conducting state when the magnetic alignment is parallel. A second superconducting layer is adjacent to one of the ferromagnetic layers, facilitating Josephson tunneling between the two superconducting layers across one of the ferromagnetic layers.
