The hidden-measurements interpretation (HMI), also known as the hidden-measurements approach, is a realistic interpretation of quantum mechanics that was proposed in the 1980s by the Belgian physicist Diederik Aerts, and was subsequently developed over the years thanks to the work of Aerts and of a number of collaborators, such as Bruno Van Bogaert, Thomas Durt, Bob Coecke, Frank Valckenborgh, Bart D'Hooghe, Sven Aerts, Sandro Sozzo and Massimiliano Sassoli de Bianchi.
