Ultra-high Q-factor superconducting tantalum resonators on 300 mm Si wafers
R. Acharya, D. Perez Lozano, Ts. Ivanov +13
Superconducting resonators are central to superconducting quantum information technologies and essential for bosonic qubit architectures, where long-lived storage modes enable hard…
Eight-Qubit Operation of a 300 mm SiMOS Foundry-Fabricated Device
Andreas Nickl, Nard Dumoulin Stuyck, Paul Steinacker +24
Silicon spin qubits are a promising platform for quantum computing due to their high coherence, controllability, and CMOS manufacturability, yet scalable implementations have so fa…
Concatenated continuous driving of silicon qubit by amplitude and phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +22
The rate of coherence loss is lower for a qubit under the Rabi drive than a freely evolving qubit . Building on this principle, concatenated continuous d…
Reversing Hydrogen-Related Loss in -Ta Thin Films for Quantum Device Fabrication
D. P. Lozano, M. Mongillo, B. Raes +10
-Tantalum (-Ta) is an emerging material for superconducting qubit fabrication due to the low microwave loss of its stable native oxide. However, hydrogen absorption during…
