Time-domain characterization and correction of on-chip distortion of control pulses in a quantum processor

We introduce Cryoscope, a method for sampling on-chip baseband pulses used to dynamically control qubit frequency in a quantum processor. We specifically use Cryoscope to measure the step response of the dedicated flux control lines of two-junction transmon qubits in circuit QED processors with the temporal resolution of the room-temperature arbitrary waveform generator producing the control pulses. As a first application, we iteratively improve this step response using optimized real-time digital filters to counter the linear-dynamical distortion in the control line, as needed for high-fidelity, repeatable one- and two-qubit gates based on dynamical control of qubit frequency

While gambling has traditionally been viewed as an adult activity, there is a growing body of research that a significant number of adolescents are not only gambling but are experiencing gambling related problems. As ease of access via Internet wagering has increased, so too have some of the concomitant problems. Social casino gambling, often thought of gambling without risking one's money through the use of virtual currency, has become increasingly popular. The current review examines whether we should be concerned over its widespread use and whether such social games should be regulated.This research review was partially funded by the Manitoba Gambling Research Program of Manitoba Lotteries; however, the findings and conclusions of this paper are those solely of the authors and do not necessarily represent the views of Manitoba Lotteries
