Unitary evolution and projective measurement are fundamental axioms of quantum mechanics. Even though projective measurement yields one of the eigenstates of the measured operator as the outcome, there is no theory that predicts which eigenstate will be observed in which experimental run. There exists only an ensemble description, which predicts probabilities of various outcomes over many experimental runs. We propose a dynamical evolution equation for the projective collapse of the quantum state in individual experimental runs, which is consistent with the well-established framework of quantum mechanics. In case of gradual weak measurements, its predictions for ensemble evolution are different from those of the Born rule. It is an open question whether or not suitably designed experiments can observe this alternate evolution.Keywords

The World Vegetable Center, Taiwan regards traditional vegetables as one of the important means of ‘climate-resilient pathways’. Momordica sahyadrica is a lesser-known traditional vegetable having neutraceutical virtues. It grows well under marginal input and partial shade environment, thereby, it aptly highlights one of its niche attributes, ‘climate resilience’. It is endemic to the typical habitat of the Western Ghats (Sahyadri mountain range) and is a distinguished species of the well-known vegetable genus Momordica. Popularizing this species, conservation through cultivation, and further focused research and development using various techniques will facilitate the recovery of promising genotypes and mainstreaming of this Sahyadri gourdKeywords
