Tantalum as a base material for superconducting integrated circuits
Evgeniy V. Zikiy, Nikita S. Smirnov, Stanislav A. Kotenkov +9
The performance of superconducting integrated circuits for quantum applications is fundamentally limited by material-related losses. Tantalum, as an emerging material for next-gene…
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…
Superconducting integrated on-demand quantum memory with microwave pulse preservation
Aleksei R. Matanin, Nikita S. Smirnov, Anton I. Ivanov +8
Microwave quantum memory represents a critical component for quantum radars and resource-efficient approaches to quantum error correction. Superconducting microwave resonators prov…
Lumped-element two-section impedance-matched SNAIL parametric amplifier
D. Moskaleva, N. Smirnov, D. Moskalev +11
Broadband impedance-matched Josephson parametric amplifiers are key components for high-fidelity single-shot multi-qubit readout. Nowadays, several types of impedance matched param…
Wafer-scale uniformity improvement of Dolan-bridge Josephson junction by shadow evaporation bias correction
Daria A. Moskaleva, Nikita D. Korshakov, Dmitry O. Moskalev +7
One of the practical limitations of solid-state superconducting quantum processors technology is frequency crowding due to low qubits fabrication reproducibility. Josephson junctio…
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…
