text: "In the last few decades, there has been much progress on low loss
waveguides, very efficient photon-number detectors and nonlinear processes. Engineered
sum-frequency conversion is now at a stage where it allows operation on arbitrary
temporal broadband modes, thus making the spectral degree of freedom accessible
for information coding. Hereby the information is often encoded into the temporal
modes of a single photon. Here, we analyse the prospect of using multi-photon
states or squeezed states in different temporal modes based on integrated optics
devices. We describe an analogy between mode-selective sum-frequency conversion
and a network of spatial beam splitters. Furthermore, we analyse the limits on
the achievable squeezing in waveguides with current technology and the loss limits
in the conversion process.\r\n This article is part
of the themed issue ‘Quantum technology for the 21st century’."

text: "\r\n We examine for the first time how chemically and
thermally stable gold nanoparticles (NPs), prepared by a silane conjugation approach,
affect both the thermal and the electro-optical properties of a nematic liquid
crystal (LC), when doped at concentrations ranging from 0.25 to 7.5 wt%. We find
that the octadecylsilane-conjugated gold NPs stabilize both the enantiotropic
nematic and the monotropic smectic-A phases of the LC host with a maximum stabilization
of 2\r\n °\r\n C for the nematic and
3.5\r\n °\r\n C for the smectic-A phases
for the mixture containing 1 wt% of the silanized particles. The same mixture
shows the lowest values for the Fréedericksz transition threshold voltage and
the highest value for the dielectric anisotropy. Generally, all NP-containing
mixtures, except mixtures with NP concentrations exceeding 5 wt%, reduce the threshold
voltage, increase the dielectric anisotropy and reduce both rise and decay time;
the latter particularly at temperatures at least 10\r\n °\r\n
\ C below the isotropic–nematic phase transition on cooling.\r\n "
