Abstract: A method for a computing system includes beaming with a radar emitter from a central hub, a plurality of radar signals into an interior room, receiving with a radar receiver within the central hub, a plurality of radar reflections in response to the plurality of radar signals, processing with a processor within the central hub, the plurality of radar reflections to form a plurality of processed radar signals, determining with an AI processor within the central hub, at least one activity from a plurality of activities in response to the plurality of processed radar signals, and determining with a central processing unit within the central hub, a notification action to perform in response to the one or more activities.

Abstract: In an example, the present invention provides a method for identifying a status of a user and providing feedback to the user based upon the status of the user. In an example, the method includes generating an electromagnetic radio frequency (RF) signal from an RF generating device and emitting the electromagnetic RF signal into a spatial region of a user. In an example, the method includes detecting a back scattered RF signal, using an RF receiving antenna, from the user and converting the back scattered RF signal from an RF analog signal into an RF digital signal.

Abstract: A method of measuring states of qubits of a quantum processor, the method includes providing, to the qubits, a control signal to control states of n qubits in the quantum processor, where n is a natural number; performing a bit-flip to invert a state of at least one qubit of the qubits; reading out output qubit values of bit-flipped qubits based on the performing of the bit-flip; and generating an error model indicating a probability of occurrence of measurement errors in the output qubit values based on a result of the reading-out of the output qubit values.
