Photon-efficient quantum key distribution using time–energy entanglement with high-dimensional encoding

New Journal of Physics, 2015
Conventional quantum key distribution (QKD) typically uses binary encoding based on photon polarization or time-bin degrees of freedom and achieves a key capacity of at most one bit per photon. Under photon-starved conditions the rate of detection events

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry

Bulletin of the Korean Chemical Society, EarlyView.
Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Tannic acid–metal biomaterials for skin repair: Principles, immune microenvironment modulation, and translational perspectives

BMEMat, EarlyView.
Tannic acid–metal materials are emerging as versatile wound biomaterials, but their value depends on more than multifunctionality. This review maps how tannic acid alone, free metal ions, and coordinated TA–metal systems differ in design logic, immune‐microenvironment effects, and translational potential, offering a practical framework for choosing ...

Some self-adjoint quantum semimartingales [PDF]

, 2006
It is proved that the quantum stochastic gauge integral preserves self-adjointness of vacuum-adapted processes. This fact, together with bounded perturbations and the link between the Hudson–Parthasarathy calculus and vacuum-adapted theory, is used to ...
