Tantalum (Ta) has recently emerged as a promising low-loss material, enabling record coherence times in superconducting qubits. This enhanced performance is largely attributed to its stable native oxide, which is believed to host fewer two-level system (TLS) defects– key contributors to decoherenc ...

Nanomechanical resonators promise diverse applications from mass spectrometry to quantum information processing, requiring long phonon lifetimes and frequency stability. Although two-level-system (TLS) defects govern dissipation at millikelvin temperatures, the nature of frequency fluctuations rema ... Read More>>October-23，2025 -
Utilizing tantalum (Ta) in superconducting circuits has led to significant improvements, such as high qubit lifetime (T1) and quality factors in both qubits and resonators, suggesting that material optimization plays an important role in the development of superconducting circuits. Thus we here ... Read More>>October-23，2025 -
Resonant phase-matched Josephson traveling-wave parametric amplifiers (RPM JTWPAs) play a key role in quantum computing and quantum information applications due to their low-noise, broadband amplification, and quadrature squeezing capabilities. This research focuses on optimizing RPM ... Read More>>October-23，2025 -
