Optimization of periodic single-photon sources based on combined multiplexing [PDF]
, 2016 We consider periodic single-photon sources with combined multiplexing in which the outputs of several time-multiplexed sources are spatially multiplexed.

Diversity versus Multiplexing at Finite Blocklength
, 2014 A finite blocklenth analysis of the diversity-multiplexing tradeoff is presented, based on nonasymptotic bounds on the maximum channel coding rate of multiple-antenna block-memoryless Rayleigh-fading channels.The bounds in this paper allow one to ...

Barcoded multiple displacement amplification for high coverage sequencing in spatial genomics
Nature Communications, 2023 Determining mutational landscapes in a spatial context is essential for understanding genetically heterogeneous cell microniches. Current approaches, such as Multiple Displacement Amplification (MDA), offer high genome coverage but limited multiplexing ...

Analysis of IEEE 802.11N-like transmission techniques with and without prior CSI for video applications [PDF]
, 2007 Previous research into MIMO systems has focused little on optimisation for video transmission. In terms of multimedia transmission, spatial multiplexing (SM) is commonly proposed as the most suitable MIMO technique.

Spatial Division Multiplexing for Multiplex Coherent Anti-Stokes Raman Scattering
Journal of Lightwave Technology, 2023 We demonstrate how a narrowband pump and a broadband spectrum can be spatially multiplexed by selective coupling them in two distinct modes of a few-mode microstructure fiber. The first mode carries most of the input pump energy, and experiences spectral broadening.

Integrated spatial multiplexing of heralded single photon sources
, 2013 The non-deterministic nature of photon sources is a key limitation for single photon quantum processors. Spatial multiplexing overcomes this by enhancing the heralded single photon yield without enhancing the output noise.
