Considering again Figure 15.4.1, we see that a screen along C 1 will not filter any water as no water passes across that curve. (Coupons are sent out around the 5th of the month after pledge has posted. The opposite of flow is flux, a measure of how much water is moving across the path C.If a curve represents a filter in flowing water, flux measures how much water will pass through the filter. These results open the door to integration of large-scale superconducting qubit arrays with SFQ control elements for low-latency feedback and stabilization. I'll also record a personalized video just for you so that I can show my gratitude. We characterize the dissipative and dispersive contributions of the quasiparticle admittance and discuss mitigation strategies to suppress quasiparticle poisoning. Gate fidelities are limited by quasiparticle generation in the dissipative SFQ driver. We measure the fidelity of SFQ-based gates to be ~95% using interleaved randomized benchmarking. The pulse driver delivers trains of quantized flux pulses to the qubit through a weak capacitive coupling coherent rotations of the qubit state are realized when the pulse-to-pulse timing is matched to a multiple of the qubit oscillation period. Here we implement coherent control of a superconducting transmon qubit using a Single Flux Quantum (SFQ) pulse driver cofabricated on the qubit chip. A longstanding goal of the superconducting qubit community is the tight integration of a superconducting quantum circuit with a proximal classical cryogenic control system. In addition, the physical resources required to implement gates must scale efficiently with system size. and 17 other authors Download PDF Abstract:High-fidelity gate operations are essential to the realization of a fault-tolerant quantum computer.
