Patent number: 11962688Abstract: Secure, semi-classical authentication schemes are presented. An authentication token is generated by applying a pre-determined measurement to a plurality of random quantum states to obtain a sequence of classical measurement outcomes. The token is validated by receiving the classical measurement outcomes and verifying whether the sequence corresponds to a statistically plausible result for the pre-determined measurement of the plurality of quantum states.Type: GrantFiled: July 25, 2022Date of Patent: April 16, 2024Assignees: Quantinuum LimitedInventor: Adrian Kent

Publication number: 20110253291Abstract: The invention provides a drywall finishing method. The method may include the steps of taping one or more drywall joints with drywall tape and allowing drying; applying a coat of joint compound composition covering substantially all of the drywall tape and allowing to dry; and applying a finishing coat of joint compound composition to substantially all of a drywall surface and allowing to dry. The invention further provides a joint compound composition suitable for use in the method of finishing drywall, wherein the joint compound composition comprises a composition compatible with conventional jointing compound material and exhibits improved properties of thickness, self leveling, elasticity, durability, photographing and/or mold resistance over that of conventional joint compound compositions.Type: ApplicationFiled: April 20, 2011Publication date: October 20, 2011Applicant: LEVEL 7, LLCInventors: Brian C. Allen, Adrian Kent Allen

Patent number: 7483142Abstract: A security system uses a source capable of producing an entangled state of a sensing mode and a reference mode. The sensing mode has a path that enters an area around an object being secured. A state measurement system in the security system can measure a combination of the sensing mode after traversal of the sensing path and the reference mode after traversal of a reference path.Type: GrantFiled: May 3, 2006Date of Patent: January 27, 2009Assignee: Hewlett-Packard Development Company, L.P.Inventors: Adrian Kent, William J. Munro, Timothy P. Spiller, Raymond G. Beausoleil, Jr.
