摘要： Systems and methods of quantum sensing include obtaining information regarding a target signal in electronic spin states of quantum defects in an ensemble of quantum defects, mapping the information regarding the target signal from the electronic spin states of the quantum defects to corresponding nuclear spin states associated with the quantum defects, applying a light pulse to the ensemble of quantum defects to reset the electronic spin states of the quantum defects, and repeating a readout stage a plurality of times within a readout duration. The readout stage includes mapping the information regarding the target signal back from the nuclear spin states to the corresponding electronic spin states and applying a data acquisition readout pulse to optically measure the electronic spin states of the quantum defects.

摘要： Embodiments are disclosed for generating continuous curve textures based on an input exemplar. A method of generating continuous curve textures may include receiving an input exemplar which represents a repetitive pattern as a plurality of vector curves, generating an input graph representation of the input exemplar which represents a geometry and a topology of the input exemplar, synthesizing an output graph based on the input graph representation, and reconstructing output vector curves from the output graph.

摘要： A method for detecting a two-qubit correlated dephasing error includes accessing a signal of a quantum system, where the quantum system includes a plurality of qubits. Every qubit has a nonzero rate of dephasing and some qubits have a nonzero rate of correlated dephasing. The signal further includes information about a matrix that includes diagonal elements and off-diagonal elements. The off-diagonal elements of the matrix are 2 s-sparse. The method further includes performing randomized measurements of the off-diagonal elements of the matrix and recovering the matrix based on a direct measurement of the diagonal elements of the matrix.

摘要： A pulse combustor system for operating pulse combustors in anti-phase. The pulse combustor system includes two pulse combustors connected at their combustion chambers by a connecting tube. Each of the pulse combustors has a fundamental oscillation mode and one or more additional oscillation modes when operated in isolation. The connecting tube has a length corresponding to ¼ of the fundamental oscillation mode wavelength.

摘要： Aspects of the present disclosure describe techniques for controlling coherent crosstalk errors that occur in multi-channel acousto-optic modulators (AOMs) by applying cancellation tones to reduce or eliminate the crosstalk errors. For example, a method and systems are described that include applying a first radio frequency (RF) tone to generate a first acoustic wave in a first channel of the multi-channel AOM, wherein a portion of the first acoustic wave interacts with a second channel to cause a crosstalk effect, and applying a second RF tone to generate a second acoustic wave in the second channel, wherein the second acoustic wave reduces or eliminates the crosstalk effect caused by the portion of the first acoustic wave.

摘要： Methods and compositions for the production of cardiomyocytes and cardiac organoids from the differentiation of pluripotent stem cells in three-dimensional (3D) culture are provided. Rock inhibitor, which has been ubiquitously used as a medium supplement to prevent apoptosis during handling and culture of pluripotent stem cells, compromises the capacity of cardiac differentiation of pluripotent stem cells in 3D culture at the most commonly used concentrations.

摘要： A confidentiality preserving system and method for performing a rank-ordered search and retrieval of contents of a data collection. The system includes at least one computer system including a search and retrieval algorithm using term frequency and/or similar features for rank-ordering selective contents of the data collection, and enabling secure retrieval of the selective contents based on the rank-order. The search and retrieval algorithm includes a baseline algorithm, a partially server oriented algorithm, and/or a fully server oriented algorithm. The partially and/or fully server oriented algorithms use homomorphic and/or order preserving encryption for enabling search capability from a user other than an owner of the contents of the data collection. The confidentiality preserving method includes using term frequency for rank-ordering selective contents of the data collection, and retrieving the selective contents based on the rank-order.
