A group of scientists from the Raman Research Institute, Bangalore measured the spin properties of atoms cooled at micro-Kelvin temperatures and observed an increase in the efficiency of the quantum systems.

ABOUT THE STUDY:

• The scientists developed a new technique to study the correlation between waves in the atoms which are long-lived at ultra-low temperatures and their implication in the quantum properties of atoms.
• The long-lived spin coherence is a better resource as quantum computers as it allows better quantum operations than the systems with short-lived spin coherences.
• At Spin is a fundamental quantum property of an atom and its elementary particles like electrons and protons. At low temperatures, the quantum properties become more prominent.
• The scientists measured the spin dynamics of the atoms at absolute zero temperature using polarization fluctuation measurements; at this temperature, quantum properties dominate over classical observations.
• They used laser cooling techniques to cool down the neutral atoms near absolute zero temperatures.
