In 2012 the idea of counterfactual quantum communication has been proposed and demonstrated. Its first achievement was reported in 2017. According to contemporary conceptions of counterfactual quantum communication, information can thereby be exchanged without any physical particle / matter / energy

and without the information being the absence of a signal. In 2020 research suggested that this is based on some form of relation between the properties of modular angular momentum with massless current of modular angular momentum current crossing the "transmission channel" with their
55:. Examples include Keith Bowden's Counterfactual Mirror Array describing a digital computer that could be counterfactually interrogated to calculate whether a light beam would fail to pass through a maze.
