Publication number: 20180052806Abstract: Among the embodiments disclosed herein are example methods for generating all Clifford gates for a system of Majorana Tetron qubits (quasiparticle poisoning protected) given the ability to perform certain 4 Majorana zero mode measurements. Also disclosed herein are example designs for scalable quantum computing architectures that enable the methods for generating the Clifford gates, as well as other operations on the states of MZMs. These designs are configured in such a way as to allow the generation of all the Clifford gates with topological protection and non-Clifford gates (e.g. a ?/8-phase gate) without topological protection, thereby producing a computationally universal gate set. Several possible realizations of these architectures are disclosed.Type: ApplicationFiled: June 28, 2017Publication date: February 22, 2018Applicant: Microsof Technology Licensing, LLCInventors: Matthew Hastings, Torsten Karzig, Parsa Bonderson, Michael Freedman, Roman Lutchyn, Chetan Nayak

Patent number: 8620835Abstract: Disclosed herein is a protocol that enables the ?/8-gate in chiral topological superconductors in which superconducting stiffness ? has been suppressed. The protocol enables a topologically protected ?/8-gate in any pure Ising system that can be fabricated into genus=1 surface. By adding the ?/8-gate to previously known techniques, a design for universal topologically protected quantum computation which may be implemented using rather conventional materials may be obtained.Type: GrantFiled: December 28, 2010Date of Patent: December 31, 2013Assignee: Microsoft CorporationInventors: Michael Freedman, Parsa Bonderson, Chetan Nayak, Sankar Das Sarma

Patent number: 8606341Abstract: A twisted track interferometer (TTI) for producing magic states is disclosed. The spin of ½-vortices may be exploited to produce magic states. The disclosed “twisted track interferometer” is a “topological twist” on the conventional Pabre-Pero interferometer adapted to topological superconductors. In the disclosed TTI, the probe particles may be Josephson vortices (JVs). JVs are estimated to be light and will tunnel more easily than Abrikosov vortices. Also, the disclosed TTI does not require multiple tunneling events. Rather, the JVs are propelled down thin insulating tracks within a 2D topological p-wave superconductor by a Magnus force generated by a tunneling supercurrent across the tracks. The JVs encounter tunneling junctions as they pass into the arms of the TTI.Type: GrantFiled: December 27, 2011Date of Patent: December 10, 2013Assignee: Microsoft CorporationInventors: Parsa Bonderson, Lukasz Fidkowski, Michael Freedman, Roman Lutchyn, Chetan Nayak

Patent number: 8581227Abstract: A computer-implemented method for encryption and decryption using quantum computational model is disclosed. Such a method includes providing a model of a lattice having a system of non-abelian anyons disposed thereon. From the lattice model, a first quantum state associated with the lattice is determined. Movement of non-abelian anyons within the lattice is modeled to model formation of first and second quantum braids in the space-time of the lattice. The first quantum braid corresponds to first text. The second quantum braid corresponds to second text. A second quantum state associated with the lattice is determined from the lattice model after formation of the first and second quantum braids has been modeled. The second quantum state corresponds to second text that is different from the first text.Type: GrantFiled: September 27, 2011Date of Patent: November 12, 2013Assignee: Microsoft CorporationInventors: Michael Freedman, Chetan Nayak, Kirill Shtengel

Patent number: 8275428Abstract: Disclosed herein is a topologically protected ?/8-gate which becomes universal when combined with the gates available through quasi-particle braiding and planar quasi-particle interferometry. A twisted interferometer, and a planar ?/8-gate in CTS, implemented with the help of the twisted interferometer, are disclosed. Embodiments are described in the context of state X (CTS) supported by an ISH, although the concept of a twisted-interferometer is more general and has relevance to all anionic, i.e. quasiparticle systems.Type: GrantFiled: March 31, 2011Date of Patent: September 25, 2012Assignee: Microsoft CorporationInventors: Parsa Bonderson, Michael Freedman, Chetan Nayak, Kevin Walker, Lukasz Fidkowski
