=== [[Marissa Giustina|Giustina]] et al. (2013), Larsson et al (2014): overcoming the detection loophole for photons ===
The detection loophole for photons has been closed for the first time by [[Marissa Giustina]], using [[Transition edge sensor|highly efficient detectors]]. This makes photons the first system for which all of the main loopholes have been closed, albeit in different experiments.<ref name="giustina">{{cite journal|last=Giustina|first=Marissa|author2=Alexandra Mech|author3=Sven Ramelow|author4=Bernhard Wittmann|author5=Johannes Kofler|author6=Jörn Beyer|author7=Adriana Lita|author-link7=Adriana Lita|author8=Brice Calkins|author9=Thomas Gerrits|author10=Sae Woo Nam|author11=Rupert Ursin|date=2013-04-14|title=Bell violation using entangled photons without the fair-sampling assumption|journal=Nature|volume=497|issue=7448|pages=227–30|arxiv=1212.0533|bibcode=2013Natur.497..227G|doi=10.1038/nature12012|pmid=23584590|author12=Anton Zeilinger|s2cid=18877065 }}</ref><ref name = "larsson"/>
