Quantum noise reduction method for enhanced precision in atomic clocks

(Springer) Finding ways to reduce quantum noise can enhance the precision of measurement in atomic fountain clocks or in methods used for quantum information processing. A team of physicists including Aranya Bhattacherjee from Jawaharlal Nehru University, New Delhi, India and colleagues is now investigating ways of improving the analysis of quantum noise measurement in the case of spectroscopic investigations; their preliminary findings were released in a study in EPJ D.
