Patents by Inventor Dmitry I. Pikulin

Dmitry I. Pikulin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11010684
    Abstract: This application concerns quantum computing, and in particular to structures and mechanisms for providing topologically protected quantum computation. In certain embodiments, a magnetic tunnel barrier is controlled that separates Majorona zero modes (“MZMs”) from an edge area (e.g., a gapless edge) of a quantum spin hall system. In particular implementations, the magnetic tunnel barrier is formed from a pair of magnetic insulators whose magnetization is held constant, and the magnetic tunnel barrier is tuned by controlling a gate controlling the electron density around the magnetic insulator in the QSH plane, thereby forming a quantum dot. And, in some implementations, a state of the quantum dot is read out (e.g., using a charge sensor as disclosed herein).
