Patent number: 11715026Abstract: Systems and methods for performing open-loop quantum error mitigation using quantum measurement emulations are provided. The open-loop quantum error mitigation methods do not require the performance of state readouts or state tomography, reducing hardware requirements and increasing overall computation speed. To perform a quantum measurement emulation, an error mitigation apparatus is configured to stochastically apply a quantum gate to a qubit or set of qubits during a quantum computational process. The stochastic application of the quantum gate projects the quantum state of the affected qubits onto an axis, reducing a trace distance between the quantum state and a desired quantum state.Type: GrantFiled: June 30, 2020Date of Patent: August 1, 2023Assignee: Massachusetts Institute of TechnologyInventors: William Oliver, Seth Lloyd, Danna Rosenberg, Michael O'Keeffe, Amy Greene, Morten Kjaergaard, Mollie Schwartz, Gabriel Samach, Iman Marvian Mashhad

Patent number: 11699091Abstract: Qubit circuits having components formed deep in a substrate are described. The qubit circuits can be manufactured using existing integrated-circuit technologies. By forming components such as superconducting current loops, inductive, and/or capacitive components deep in the substrate, the footprint of the qubit circuit integrated within the substrate can be reduced. Additionally, coupling efficiency to and from the qubit can be improved and losses in the qubit circuit may be reduced.Type: GrantFiled: January 4, 2021Date of Patent: July 11, 2023Assignee: Massachusetts Institute of TechnologyInventors: Wayne Woods, Danna Rosenberg, Cyrus Hirjibehedin, Donna-Ruth Yost, Justin Mallek, Andrew Kerman, Mollie Schwartz, Jonilyn Yoder, William Oliver, Thomas Hazard

Patent number: 10134972Abstract: A cryogenic quantum bit package with multiple qubit circuits facilitates inter-qubit signal propagation using a multi-chip module (MCM). Multiple qubits are grouped within the package into one or more qubit integrated circuits (ICs). The qubit ICs themselves are electrically coupled to each other via a structure including a superconducting MCM and superconducting interconnects. Coupling of quantum electrical signals between a qubit and other qubits, a substrate, or the MCM uses a coupler circuit, such as a Josephson junction, capacitor, inductor, or resonator.Type: GrantFiled: November 3, 2016Date of Patent: November 20, 2018Assignee: Massachusetts Institute of TechnologyInventors: William D.

Patent number: 10121754Abstract: A method of fabricating an interconnect structure includes providing a semiconductor structure and performing a first spin resist and bake cycle. The first spin resist and bake cycle includes applying a first predetermined amount of a resist material over one or more portions of the semiconductor structure and baking the semiconductor structure to form a first resist layer portion of a resist layer. The method also includes performing a next spin resist and bake cycle. The next spin resist and bake cycle includes applying a next predetermined amount of the resist material and baking the semiconductor structure to form a next resist layer portion of the resist layer. The method additionally includes depositing a conductive material in an opening formed in the resist layer and forming a conductive structure from the conductive material. An interconnect structure is also provided.Type: GrantFiled: November 3, 2016Date of Patent: November 6, 2018Assignee: Massachusetts Institute of TechnologyInventors: William D. Oliver, Andrew J.

Patent number: 9680641Abstract: Techniques and tools for quantum key distribution (“QKD”) between a quantum communication (“QC”) card, base station and trusted authority are described herein. In example implementations, a QC card contains a miniaturized QC transmitter and couples with a base station. The base station provides a network connection with the trusted authority and can also provide electric power to the QC card. When coupled to the base station, after authentication by the trusted authority, the QC card acquires keys through QKD with a trust authority. The keys can be used to set up secure communication, for authentication, for access control, or for other purposes. The QC card can be implemented as part of a smart phone or other mobile computing device, or the QC card can be used as a fillgun for distribution of the keys.Type: GrantFiled: April 6, 2015Date of Patent: June 13, 2017Assignee: Los Alamos National Security, LLCInventors: Jane E.
