Systems, computer-implemented methods, and computer program products that can facilitate determining a state of a qubit are described. According to an embodiment, a system can comprise a memory that stores computer executable components and a processor that executes the computer executable components stored in the memory. The computer executable components can comprise an output receiving component that can receive, in response to a request, output representative of a quantum state of a qubit of a quantum computing device, and a classifying component that classifies the quantum state of the qubit of the quantum computing device based on the output representative of the quantum state of the qubit. The system can further include a configuring component that can configure the classifying component based on a characteristic of the request.

Phase-robust matched kernel acquisition for qubit state determination

A quantum circuit generator for a quantum computer includes a controller; and a plurality of analog conversion units (ACUs) operatively connected to the controller, each ACU being operatively connected to a corresponding qubit of a plurality of qubits, wherein each ACU is configured to convert a digital input from the controller into an analog input at a microwave frequency to control a quantum state of the corresponding qubit. The controller is configured to generate a quantum circuit using at least two qubits of the plurality of qubits, the at least two qubits being selected by the controller based on corresponding classical bits being mapped by the controller and based on latency of the generated quantum circuit so that the generated quantum circuit has a latency less than a threshold latency.

System and method for latency-aware mapping of quantum circuits to quantum chips

One or more systems, devices, computer program products and/or computer-implemented methods of use provided herein relate to a process to dynamically determine a threshold for determining a state of a qubit and apply the threshold for operating a pulse to de-excite the qubit. A system can comprise a memory that stores computer executable components, and a processor that executes the computer executable components stored in the memory, wherein the computer executable components can comprise a decision component that is configured to determine a threshold of a plurality of thresholds to apply to measurement of a state of a qubit based on a probability distribution of state of the qubit, wherein a measurement at one side of the threshold is representative of the qubit being in the ground state, and wherein a measurement at another side of the threshold is representative of the qubit being in an excited state.

Dynamic adaptive thresholding for qubit reset

A method includes comparing a number of memory blocks in a first pool of free memory blocks in a memory to a threshold. The memory includes memory blocks that are logically divided into the first pool, a second pool, and a third pool of memory blocks. The first pool of free memory blocks is expanded based on determining that the number of memory blocks in the first pool of free memory blocks is less than the threshold. The expanding includes: selecting a first memory block from the second pool of memory blocks, the first memory block comprising active and non-active content; selecting a second memory block from the third pool of memory blocks; copying the active content of the first memory block to the second memory block; erasing the first memory block; and adding the first memory block to the first pool of free memory blocks.

Hybrid storage system employing reconfigurable memory

A computing system includes a companion computing device having a display and a controller for transmitting a request to a host computing device; a host computing device for providing a user interface element and language support to the companion computing device; and a communication link for providing a bi-directional communication channel between the companion computing device and the host computing device.

A computing system includes a handwriting input device and a computing device, the handwriting input device including an electronic pen input device having a first tip that emits a signal having a first characteristic and second tip that emits a signal having second characteristic; a detector for detecting the characteristic of the emitted signal; and a controller, interfaced with the computing device, for selectively interpreting the emitted signal as handwriting or as control information for the computing device based on the detected characteristic of the emitted signal.

The present invention pertains to a computing system having an input system with local storage interfaced with a computing device, wherein input information is transferred from the digitizer input system to the interfaced computing device based on an adaptive transfer policy that extends the battery life of the interfaced computing device. The interfaced computing device may be a PC. The digitizer input system can support automated, selective transfer policies based on the power management configuration of the PC interfaced with the digitizer input system and user-selected transfer policies.

The present invention pertains to an input system for inputting information from a user, the input device system including at least one sheet of a writing medium having a unique identifier located thereon, a stylus input device for writing on the writing medium and emitting one or more signals, a detector for detecting said unique page identifier and stroke information from said emitted signal and local storage for storing said detected stroke information, in association with the unique identifier of said writing medium.

Use of a paper pad with uniquely identified pages in a digitizer system

To obtain a method for controlling power of a computer, a power control apparatus, and the computer which can prevent a user from feeling uneasy unnecessarily and inhibit a power-on problem from arising again. When the power switch is depressed, the power-on self test (POST) starts and if there is no error detected by that test in connection with the initialization of the IC, the operating system OS is loaded to make the computer operative (steps 200 through 208). If there is any error detected, a determination is made whether that error occurs as frequently as or more frequently than a predetermined number of times. If that error occurs as frequently as or more frequently than the predetermined number of times, an error indication is displayed and then the process ends. If that error occurs less frequently than the predetermined number of times, the error history is stored and then a setup for stabling the hardware operation is selected. Then, a restart signal to restart the computer is sent and the process ends (steps 210 through 220).
