Low-error encoder for time-bin and decoy states for quantum key distribution
Published 2025-02-01“…A key device for decoy-state QKD is the state encoder, which must produce low-error, stable states with varying photon mean values. Here, we introduce the MacZac (Mach-Zehnder-Sagnac), a time-bin encoder with ultra-low QBER (<2 × 10−5) and high stability. …”

Multi-messenger probes of asteroid mass primordial black holes: Superradiance spectroscopy, Hawking radiation, and microlensing
Published 2025-02-01“…Using axion-like particles as an example, we show that line signals emerging from a superradiated axion cloud combined with black hole Hawking radiation in extragalactic and galactic halos, along with microlensing observations lead to complementary constraints on parameter space combinations including the axion-photon coupling, axion mass, black hole mass, and its dark matter fraction, fPBH. …”

Collider and CMB complementarity of leptophilic dark matter with light Dirac neutrinos
Published 2025-01-01“…Considering DM relic to be generated via the thermal freeze-out, we check the discovery prospects at future lepton colliders via mono-photon plus missing energy searches. The right chiral parts of light Dirac neutrinos get thermalised due to their interactions with the bath as well as leptophilic DM, leading to enhanced effective relativistic degrees of freedom N eff within reach of future cosmic microwave background (CMB) experiments. …”

Near-infrared light triggered in situ release of CO for enhanced therapy of glioblastoma
Published 2023-02-01“…Results In this study, a therapeutic nanoplatform (UCNPs@Ce6/3HBQ@CM) with combination of PDT and CO therapy was constructed, in which a photoCORM and a photosensitizer were loaded onto the surface of upconversion nanoparticles (UCNPs) functioning as photon transducer. Benefitting from NIR excitation and multicolor emission of UCNPs, the penetration depth of excitation light is enhanced and meanwhile simultaneous generation of CO and ROS in tumor site can be achieved. …”
