High-fidelity two-qubit gates with transmon qubits using bipolar flux pulses and tunable couplers
Nikita S. Smirnov, Aleksei R. Matanin, Anton I. Ivanov +15
High-fidelity two-qubit gates are essential for scalable quantum computing. We present a scheme based on superconducting transmon qubits and a control pulse delivery protocol that…

Investigation of tantalum films growth for coplanar resonators with internal quality factors above ten million
E. V. Zikiy, N. S. Smirnov, E. A. Krivko +13
Alpha-tantalum on silicon is a promising platform for high-coherence superconducting quantum circuits. However, the growth mechanism of alpha-tantalum on silicon remains poorly und…
