NICER detection of a new candidate cyclotron line in the bursting X-ray pulsar GRO J1744-28
Qi Liu, Lingda Kong, Long Ji +15
We report the detection of cyclotron resonant scattering features (CRSFs) in the spectrum of the unique bursting pulsar GRO J1744-28, observed during its recent outburst in 2021 wi…
Krypton-sputtered tantalum films for scalable high-performance quantum devices
Maciej W. Olszewski, Lingda Kong, Simon Reinhardt +9
Superconducting qubits based on tantalum (Ta) thin films have demonstrated the highest-performing microwave resonators and qubits. This makes Ta an attractive material for supercon…
Compact non-degenerate entangled-photon source and near-infrared-to-telecom quantum teleportation
Xu-Jie Peng, Ling-Xuan Kong, He Lu
The polarization-entangled photon source (PEPS) at non-degenerated wavelengths is pivotal to connect quantum systems working at different wavelengths, with the assistance of quantu…
Quantum-Limited Optical Vector Analysis
Karthik Dasigi, Pavel A. Dmitriev, Kah Jen Wo +3
Optical Vector Analysers (OVA) are critical for emerging technologies such as integrated photonics and optical positioning. Achieving a sensitivity near the Standard Quantum Limit…
