Zhu, Shaoli; Zhou, Wei
Electric field distribution is one of the important parameters for nanostructure arrays in nanobiosensing applications. It can influence the sensitivity and the resolution of nanobiosensors. We focus on the effect of media on electric field distribution of a rhombic silver nanostructure array. Finite-difference time-domain algorithm-based numerical calculation method is used to monitor the electric field distribution of the silver nanostructures when the refractive index of medium around the nanostructure array is changed. The calculated results show that tuning the refractive index of the medium around silver can have considerable influence on the electric field distribution in the reflection and transmission directions. This effect can be used to increase the extinction efficiency and to improve the resolution of the spectra for nanobiosensing.

Datta, Nilanjana; Hsieh, Min-Hsiu
We consider the scenario in which Alice transmits private classical messages to Bob via a classical-quantum channel, part of whose output is intercepted by an eavesdropper Eve. We prove the existence of a universal coding scheme under which Alice's messages can be inferred correctly by Bob, and yet Eve learns nothing about them. The code is universal in the sense that it does not depend on specific knowledge of the channel. Prior knowledge of the probability distribution on the input alphabet of the channel, and bounds on the corresponding Holevo quantities of the output ensembles at Bob's and Eve's end suffice

In this Rapid Communication, we consider the open problem of the minimum cost of two-qubit gates for simulating the Toffoli gate and show that five two-qubit gates are necessary. Before our work, it was known that five two-qubit gates are sufficient to i

In 1991, Peres and Wootters wrote a seminal paper on the nonlocal processing of quantum information [Phys. Rev. Lett. 66, 1119 (1991)]. We return to their classic problem and solve it in various contexts. Specifically, for discriminating the 'double trin
