Midcircuit measurement and reset are crucial primitives in quantum computation, but such operations require strong interactions with selected qubits while maintaining isolation of neighboring qubits, which is a significant challenge many systems. For trapped ion systems, performed laser-induced fluorescence. Stray light from the detection beam fluorescence measured ions can be sources decoheren...

The use of high-precision measuring instruments for determining the torque electric motors in such areas as medicine, motor transport, shipping, aviation requires improvement metrological characteristics instruments. This, turn, an accurate assessment their error. Of particular importance is measurement power at high-speed installations, where some cases conventional systems are either unsuitab...

Quantum technologies available currently contain noise in general, often dubbed noisy intermediate-scale quantum (NISQ) systems. We here present the verification of measurement readout errors cloud-based computing services, IBMQ and Rigetti, by directly performing detector tomography, show that there exist crosstalk errors. provide characterization quantification a multiple qubits. remark entan...
