Patent number: 11177428Abstract: A flux-biasing device includes a set of magnetic flux generating members. A first magnetic flux generating member is configured to magnetically interact with a first qubit from a set of qubits of a quantum processor such that a first magnetic flux of the first member causes a first change in a first resonance frequency of the first qubit by a first frequency shift value. Each non-corresponding magnetic flux generating member of the set is well separated from qubits corresponding to other magnetic flux generating members of the set such that qubits corresponding to other members exhibit less than a threshold value of resonance frequency shift as a result of a magnetic flux of a non-corresponding member.Type: GrantFiled: April 3, 2020Date of Patent: November 16, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Oblesh Jinka, Baleegh Abdo

Publication number: 20210068320Abstract: Techniques regarding shielding one or more superconducting devices are provided. For example, one or more embodiments described herein can comprise an apparatus, which can comprise a multi-layer enclosure that shields a superconducting device from a magnetic field and radiation. Further, the multi-layer enclosure can comprise a superconducting material layer that can have a thickness that inhibits a penetration of the multi-layer enclosure by the magnetic field. The multi-layer enclosure can also comprise a metal layer adjacent to the superconducting material layer. The metal layer can have a high thermal conductivity that achieves thermalization with the superconducting material layer. Moreover, the multi-layer enclosure can comprise a radiation shield layer adjacent to the superconducting material layer.Type: ApplicationFiled: August 30, 2019Publication date: March 4, 2021Inventors: Daniela Florentina Bogorin, Sean Hart, Patryk Gumann, Nicholas Torleiv Bronn, Salvatore Bernardo Olivadese, Oblesh Jinka

Publication number: 20200404806Abstract: A thermalization structure is formed using a cover configured with a set of pillars, the cover being a part of a cryogenic enclosure of a low temperature device (LTD). A chip including the LTD is configured with a set of cavities, a cavity in the set of cavities having a cavity profile. A pillar from the set of pillars and corresponding to the cavity has a pillar profile such that the pillar profile causes the pillar to couple with the cavity of the cavity profile within a gap tolerance to thermally couple the chip to the cover for heat dissipation in a cryogenic operation of the chip.Type: ApplicationFiled: June 19, 2019Publication date: December 24, 2020Applicant: International Business Machines CorporationInventors: Oblesh Jinka, Salvatore Bernardo Olivadese, Sean Hart, Nicholas Torleiv Bronn, Jerry M.

Patent number: 10833241Abstract: A thermalization structure is formed using a foil and a low temperature device (LTD). The foil includes a first layer of a first material. The LTD includes a surface from which heat is transferred away from the LTD. A coupling is formed between the foil and the surface of the LTD, where the coupling includes a bond formed between the foil and the surface such that forming the bond forms a set of ridges in the foil, a ridge in the set of ridges operating to dissipate the heat.Type: GrantFiled: June 20, 2019Date of Patent: November 10, 2020Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Eric Peter Lewandowski, Bucknell C.
