Two-photon emission is a relatively weak emission process, about five orders of magnitude weaker than the usual single-photon emission that occurs in semiconductor lasers or LEDs. So we had to use ...

Entanglement means the two-photon state is not a classical combination ... into entanglement along potassium ion channels in the neuron. If so, the opening and closing of one channel may affect ...

In the study "Transcriptomic neuron types vary topographically in ... Multiplexed in situ hybridization and two-photon calcium imaging were used to examine the spatial organization, morphology ...
