Systems, computer-implemented methods, and computer program products to facilitate generation of a visualization scheme of noise in a quantum circuit are provided. According to an embodiment, a system can comprise a processor that executes computer executable components stored in memory. The computer executable components can comprise a calculation component that can calculate a noise state of a layer in a quantum circuit. The computer executable components can further comprise a visualization component that can render a visual representation of the noise state at the layer in the quantum circuit.

Visualization scheme of noise in a quantum circuit

Systems and methods that address an optimized method to have a visual representation of qubit stochastic errors. A visual representation is generated of qubit stochastic errors that provides a platform to analyze impact on performance of a quantum circuit to facilitate understanding how noise and error impacts circuit results. Stochastic errors accumulated throughout a circuit are visualized using a gradient overlay.

Systems and techniques that facilitate electronic generation of three-dimensional quantum circuit diagrams are provided. In various embodiments, a system can comprise a data component that can access qubit topology data characterizing a quantum computing device. In various aspects, the system can further comprise a rendering component that can render a three-dimensional quantum circuit diagram based on the qubit topology data. In various instances, the qubit topology data can indicate which qubits of the quantum computing device are coupled together. In various cases, the rendering component can render the three-dimensional quantum circuit diagram by generating a two-dimensional qubit configuration model of the quantum computing device based on which qubits of the quantum computing device are coupled together, by extruding one or more qubit lines three-dimensionally outward from the two-dimensional qubit configuration model, and by rendering one or more quantum gates on the one or more qubit lines.

A method, system, and computer program product for visualizing a machine learning model are provided. A confusion matrix and model performance metric data are received from a classification model. For each data point in the confusion matrix, a corresponding pixel is generated. The pixels are grouped into clusters. Each cluster represents a label in the confusion matrix. A centroid is generated for each cluster. Using the model performance metric data, a misclassification indicator arrow is generated for each misclassified data point. The misclassification indicator arrow indicates both the predicted class and the actual class. The clusters, the centroids, and the misclassification indicator arrow are displayed as a graphical visualization of the machine learning model.

Consensus vehicular collision properties determination is provided by a method that receives mobile device sensor data from mobile device(s) of vehicle occupant(s). The vehicle is a vehicle of multiple vehicles involved in a collision, and the sensor data indicates movement and position information pertaining to the collision. The method shares the packaged sensor data to a decentralized ledger that stores this as part of a collection of sensor data from across multiple mobile devices of different vehicle occupants in the vehicles involved in the collision. Extraction and correlation of data from the ledger is used to determine consensus properties of the collision. The method determines, based on the consensus properties of the collision, which of the different vehicle occupants were driving the multiple vehicles involved in the collision and behavior of those occupants driving the multiple vehicles at the time of, and following, the collision.

Gestural zoom operation of an imaging device is facilitated by receiving, by one or more processors, zoom configuration data of a user for configuring gestural zoom operation of the imaging device, where the imaging device includes a gestural zoom mode with a zoom function that is user-configurable, and by configuring for the user, by the one or more processors, the gestural zoom operation of the imaging device for the gestural zoom mode. The configuring uses the received zoom configuration data, and includes configuring the zoom function for the user and mapping a selected portion of the configured zoom function to a gestural range of the user of the imaging device.

An approach is provided in which the approach initiates a video conference between a first user utilizing a first device and a second user utilizing a second device. The first device uses a camera positioned at a first set of coordinates to capture a first live video feed of the first user from a first alignment perspective, and also displays a second live video feed of the second user on the screen at a second set of coordinates. The approach manipulates the first live video feed such that the manipulated first live video feed captures the first user from a second alignment perspective corresponding to the second set of coordinates, and transmits the manipulated first live video feed to the second device.
