Qutrit state discrimination with mid-circuit measurements
Qutrit state readout is an important technology not only for execution of
qutrit algorithms but also for erasure detection in error correction circuits
and leakage error characterization of the gate set. Conventional technique
using a specialized IQ discriminator requires memory intensive IQ data for
input, and has difficulty in scaling up the system size. In this study, we
propose the mid-circuit measurement based discrimination technique which
exploits a binary discriminator for qubit readout. Our discriminator shows
comparable performance with the IQ discriminator, and readily available for
standard quantum processors calibrated for qubit control. We also demonstrate
our technique can reimplement typical benchmarking and characterization
experiments such as leakage randomized benchmarking and state population decay
measurement.Comment: 8 pages, 5 figure
Differences in level of confidence in diabetes care between different groups of trainees: the TOPDOC diabetes study
Background
There is an increasing prevalence of diabetes. Doctors in training, irrespective of specialty, will have patients with diabetes under their care. The aim of this further evaluation of the TOPDOC Diabetes Study data was to identify if there was any variation in confidence in managing diabetes depending on the geographical location of trainees and career aspirations.
Methods
An online national survey using a pre-validated questionnaire was administered to trainee doctors. A 4-point confidence rating scale was used to rate confidence in managing aspects of diabetes care and a 6-point scale used to quantify how often trainees would contribute to the management of patients with diabetes. Responses were grouped depending on which UK country trainees were based and their intended career choice.
Results
Trainees in Northern Ireland reported being less confident in IGT diagnosis, use of IV insulin and peri-operative management and were less likely to adjust oral treatment, contact specialist, educate lifestyle, and optimise treatment. Trainees in Scotland were less likely to contact a specialist, but more likely to educate on lifestyle, change insulin, and offer follow-up advice. In Northern Ireland, Undergraduate (UG) and Postgraduate (PG) training in diagnosis was felt less adequate, PG training in emergencies less adequate, and reporting of need for further training higher. Trainees in Wales felt UG training to be inadequate. In Scotland more trainees felt UG training in diagnosis and optimising treatment was inadequate. Physicians were more likely to report confidence in managing patients with diabetes and to engage in different aspects of diabetes care. Aspiring physicians were less likely to feel the need for more training in diabetes care; however a clear majority still felt they needed more training in all aspects of care.
Conclusions
Doctors in training have poor confidence levels dealing with diabetes related care issues. Although there is variability between different groups of trainees according to geographical location and career aspirations, this is a UK wide issue. There should be a UK wide standardised approach to improving training for junior doctors in diabetes care with local training guided by specific needs.</p
New Technology/Old Technology: Comparing Lunar Grain Size Distribution Data and Methods
Laser diffraction technology generates reproducible grain size distributions and reveals new structures not apparent in old sieve data. The comparison of specific sieve fractions with the Microtrac distribution curve generated for those specific fractions shows a reasonable match for the mean of each fraction between the two techniques, giving us confidence that the large existing body of sieve data can be cross-correlated with new data based on laser diffraction. It is well-suited for lunar soils, which have as much as 25% of the material in the less than 20 micrometer fraction. The fines in this range are of particular interest because they may contain a record of important space weathering processes
