NIT Sikkim researchers show adding projectors to sequential quantum measurements achieves the algebraic maximum (2√2) violation of non-contextual inequalities, enabling assumption-free quantum dimension witnessing—key for verifying quantum registers.

Researchers construct 12 Hardy's paradoxes for the Yu-Oh set (minimal SIC system, 13 vectors), identifying all logically contextual pure states and proving no mixed states qualify, each paradox achieving success probability SP=11.1%.
