Patent number: 10469087Abstract: A method for tuning a quantum gate of a quantum computer comprises interrogating one or more qubits of the quantum computer using stored control-parameter values and yielding new data. The method further comprises computing an objective function quantifying operational quality of the quantum gate at the stored control-parameter values, such computing employing the new data in addition to a prior distribution over features used to compute the objective function. Here, the prior distribution may be obtained by previous adaptive or non-adaptive interrogation of the one or more qubits, for instance. The method further comprises updating the stored control-parameter values, expanding the prior distribution to incorporate uncertainty in the objective function at the updated control-parameter values, re-interrogating the one or more qubits using the updated control-parameter values, and re-computing the objective function using the expanded prior distribution.Type: GrantFiled: October 8, 2018Date of Patent: November 5, 2019Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Christopher Evan Granade, John King Gamble, IV, Nathan O.

Publication number: 20190318053Abstract: In this disclosure, quantum algorithms are presented for simulating Hamiltonian time-evolution e?i(A+B)t in the interaction picture of quantum mechanics on a quantum computer. The interaction picture is a known analytical tool for separating dynamical effects due to trivial free-evolution A from those due to interactions B. This is especially useful when the energy-scale of the trivial component is dominant, but of little interest. Whereas state-of-art simulation algorithms scale with the energy ?A+B???A?+?B? of the full Hamiltonian, embodiments of the disclosed approach generally scale linearly with the sum of the Hamiltonian coefficients from the low-energy component B and poly-logarithmically with those from A.Type: ApplicationFiled: April 12, 2019Publication date: October 17, 2019Applicant: Microsoft Technology Licensing, LLCInventors: Guang Hao Low, Nathan O.

Publication number: 20190220497Abstract: This application relates generally to quantum computing. In particular, this application discloses example tools and techniques for performing phase arithmetic in quantum computer environments. Embodiments of the disclosed technology allow one to multiply N phases within error ? using (N2 log(N/?) log log(1/?)) queries to the circuits that output the N constituent phases using (N(log(N)+log log(1/?))) ancillary qubits. Also disclosed are example applications of these techniques to synthesizing specific functions of phase and new error bounds for robust amplitude amplification that is quadratically better than the standard bound.Type: ApplicationFiled: January 18, 2019Publication date: July 18, 2019Applicant: Microsoft Technology Licensing, LLCInventors: Nathan O.

Publication number: 20190179871Abstract: The disclosed technology concerns example embodiments for estimating eigenvalues of quantum operations using a quantum computer. Such estimations are useful in performing Shor's algorithm for factoring, quantum simulation, quantum machine learning, and other various quantum computing applications. Existing approaches to phase estimation are sub-optimal, difficult to program, require prohibitive classical computing, and/or require too much classical or quantum memory to be run on existing devices. Embodiments of the disclosed approach address one or more (e.g., all) of these drawbacks. Certain examples work by using a random walk for the estimate of the eigenvalue that (e.g., only) keeps track of the current estimate and the measurement record that it observed to reach that point.Type: ApplicationFiled: June 29, 2018Publication date: June 13, 2019Applicant: Microsoft Technology Licensing, LLCInventors: Christopher Granade, Nathan O.

Patent number: 10316753Abstract: Pre-cooler inlet ducts that utilize active flow-control and systems and methods including the same are disclosed herein. The systems include a pre-cooler inlet duct for a jet engine that is configured to receive a pre-cooler air stream and to direct the pre-cooler air stream into a heat exchanger. The pre-cooler inlet duct includes a flow-directing surface, which defines at least a portion of the pre-cooler inlet duct, and an active flow-control device. The active flow-control device is located to modify a boundary layer fluid flow within a boundary layer adjacent the flow-directing surface to resist separation of the boundary layer from the flow-directing surface when the pre-cooler air stream flows through the pre-cooler inlet duct. The methods include methods of resisting boundary layer separation in the pre-cooler inlet duct by flowing the pre-cooler air stream across the flow-directing surface and modifying the boundary layer with the active flow-control device.Type: GrantFiled: September 19, 2014Date of Patent: June 11, 2019Assignee: The Boeing CompanyInventors: Nathan O.

Publication number: 20180349605Abstract: In this disclosure, a number of ways that quantum information can be used to help make quantum classifiers more secure or private are disclosed. In particular embodiments, a form of robust principal component analysis is disclosed that can tolerate noise intentionally introduced to a quantum training set. Under some circumstances, this algorithm can provide an exponential speedup relative to other methods. Also disclosed is an example quantum approach for bagging and boosting that can use quantum superposition over the classifiers or splits of the training set to aggregate over many more models than would be possible classically. Further, example forms of k-means clustering are disclosed that can be used to prevent even a powerful adversary from even learning whether a participant even contributed data to the clustering algorithm.Type: ApplicationFiled: June 15, 2017Publication date: December 6, 2018Applicant: Microsoft Technology Licensing, LLCInventors: Nathan O.

Patent number: 10031965Abstract: In a computing device that implements a data object classification tool, a method for classifying data may include detecting change in spatial coordinates for each of at least two of a set of data objects within a canvas space. Each of the data objects may be associated with a vector of features. A rule set may be generated based on the vector of features associated with each of the at least two data objects. The rule set may use feature(s) that explain the changed spatial coordinates. The data objects may be selectively rearranged within the canvas space by applying the generated rule set to any remaining data objects among the set of data objects so as to assign spatial coordinates to the remaining objects. For each of the data objects, the spatial coordinates may be stored as new semantic feature(s) within the vector of features for that data object.Type: GrantFiled: November 14, 2014Date of Patent: July 24, 2018Assignee: Battelle Memorial InstituteInventor: Nathan O.

Publication number: 20180165601Abstract: Quantum neural nets, which utilize quantum effects to model complex data sets, represent a major focus of quantum machine learning and quantum computing in general. In this application, example methods of training a quantum Boltzmann machine are described. Also, examples for using quantum Boltzmann machines to enable a form of quantum state tomography that provides both a description and a generative model for the input quantum state are described. Classical Boltzmann machines are incapable of this. Finally, small non-stoquastic quantum Boltzmann machines are compared to traditional Boltzmann machines for generative tasks, and evidence presented that quantum models outperform their classical counterparts for classical data sets.Type: ApplicationFiled: June 16, 2017Publication date: June 14, 2018Applicant: Microsoft Technology Licensing, LLCInventors: Nathan O.

Publication number: 20170042461Abstract: In one embodiment of the present application, an operator provides entries into the computer workstation indicative of an evaluation. Assessment of the entries takes place relative to data representative of a corresponding multiple resource neuroenergetic model for the cognitively demanding activity. Generation of an operator instruction results from the assessment that is provided to the operator through the computer workstation. The operator instruction directs the operator to take a break from the cognitively demanding activity based on the assessment.Type: ApplicationFiled: July 15, 2016Publication date: February 16, 2017Applicant: BATTELLE MEMORIAL INSTITUTEInventors: Nathan O.
