Experiment done by Indian researchers at Raman Research Institute.
Measured quantum measure ≈ 1.17, matching theory.
Used photons and a filter to select and then erase path information.
Result shows quantum measure can exceed one, unlike normal probability.
Potential use in quantum measurement techniques and computing.
They used a special filter to choose a group of photon paths and then erased the choice so the paths could mix.
The experiment gave a quantum measure of about 1.17, a little higher than the usual limit of one.
This shows that quantum rules can give numbers bigger than ordinary chances and could help future quantum computers.
