The quantum hardware can include at least a plurality of qubits. The interface can be connected to the controller and the quantum hardware, the interface being configured to control the quantum hardware based on the command signals to implement a quantum circuit configured to simulate a boundary operator that creates a mapping of boundaries of a given graph having nodes and edges. For example, the quantum circuit can be configured to simulate a boundary operator that creates a mapping of simplices of orders, e.g., of all orders, in a given simplicial complex. A method can include creating a boundary operator on a quantum computer, where a quantum circuit is built using Pauli spin operators.

Abstract: The present invention relates to a method of capturing and stabilising volatile thiol malodour generated on the human skin, comprising steps of: i) contacting the human skin with a substrate, ii) absorbing said thiol into the substrate, and iii) reacting said thiol with a thiol-capture agent. The invention also relates to a method of quantifying said thiol, a method of assessing the deodorizing performance of a cosmetic composition on the human skin.

Abstract: In an approach for guiding a visually impaired user to position a mobile device appropriately in relation to a screen so that dynamic information on the screen can be reliably extracted and conveyed to the visually impaired user, a processor receives an image captured by a camera of a mobile device. A processor performs object recognition on the image to identify a digital screen and a location of the digital screen in the image. A processor retrieves a template of the digital screen. A processor performs angle-sensitive optical character recognition (OCR) on the location of the digital screen in the image. Responsive to a processor determining text on the digital screen can be extracted, a processor conveys the text to a user. Responsive to a processor determining text on the digital screen cannot be extracted, a processor guides the user to re-orient the mobile device to capture a better image.

Abstract: In a general aspect, a position detection system includes a magnetic field generator configured to generate a time-varying magnetic field. The magnetic field generator includes a carrier assembly that defines a first axis of rotation and comprises a permanent magnet having a center of mass. The magnetic field generator also includes a drive assembly that is coupled to the carrier assembly and configured to act on the carrier assembly to rotate the permanent magnet simultaneously about the first axis of rotation and a second axis of rotation. The second axis of rotation intersects the first axis of rotation at an intersection that is offset from the center of mass of the permanent magnet. The position detection system additionally includes a computer device configured to determine a position of a sensor based on magnetic field measurements obtained by the sensor in the time-varying magnetic field.
