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…
An engineering guide to superconducting quantum circuit shielding
Elizaveta I. Malevannaya, Viktor I. Polozov, Anton I. Ivanov +10
In this review, we provide a practical guide on protection of superconducting quantum circuits from broadband electromagnetic and infrared-radiation noise by using cryogenic shield…
Aluminum Josephson junction microstructure and electrical properties modification with thermal annealing
N. D. Korshakov, D. O. Moskalev, A. A. Soloviova +7
Superconducting qubits based on Al/AlOx/Al Josephson junction are one of the most promising candidates for the physical implementation of universal quantum computers. Due to scalab…
Deterministic integration of single nitrogen-vacancy centers into nanopatch antennas
Simeon I. Bogdanov, Oksana A. Makarova, Alexei S. Lagutchev +9
Quantum emitters coupled to plasmonic nanoantennas produce single photons at unprecedentedly high rates in ambient conditions. This enhancement of quantum emitters' radiation rate…
