At Brisbane University in Australia, they have been able to measure the interference between the two light waves with as much theoretical precision as possible. An interferometer is commonly used to measure interference, but a new way of using it has been invented, causing photons to pass individually through the interferometer. In this way, they have managed to eliminate the effects that cause inaccuracy in conventional measurements and reach the limit that marks the indelible uncertainty principle of Heissenberg. According to this principle, the position and timing of a quantum particle cannot be measured simultaneously with a high degree of accuracy.
