A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

open access: yesLaser &Photonics Reviews, EarlyView.
This work constructs a fully connected reconfigurable chip‐integrated quantum key distribution network via the mode‐pairing protocol. Hybrid ECL and WSS chips cut wavelength and port overhead, realizing arbitrary‐user key sharing with merely two wavelengths.

Fabrication‐Tolerant GaAs/SiN Coupling Above the Loss Threshold for Quantum Photonic Applications

open access: yesLaser &Photonics Reviews, EarlyView.
Reliable low‐loss optical coupling between GaAs and SiN waveguides for heterogeneous integration of single‐photon sources is demonstrated. By developing a fabrication‐aware numerical design approach and accounting for experimentally measured fabrication variations and scattering losses, coupling efficiencies meeting the < 10% loss requirement for ...

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.

The Contextual Autonomy Principle: When and Why Social Service Robots Are Perceived as Ethical

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT As social service robots move into both public and private settings, perceived ethicality becomes a key condition of adoption. We propose that the same robotic capability can acquire different ethical meanings depending on context, governance form, and social presence. Across three studies, we show that restaurant (vs.

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).
