The most precise quantum thermometer in the world developed

Quantum Thermometer Nanoscale thermometers can now measure accurately the temperature variations in cells.

Scientists from the UAB and the University of Nottingham, recently published an article in which they have fixed the limits of thermometry, in other words, formally established the smallest possible fluctuation by which temperature is able to be measured – temperature being the rate of displacement of warm air.

For their project, these researchers compared the sensitivity of thermometers that were developed with just a handful of atoms, ones that are small enough that they are capable of expressing everyday quantum-style behaviors.

The researchers examined the nature of these kinds of probes in depth – devices with the potential to estimate local and regional temperatures with only a very minimal margin of error.

In order to accomplish this, they used a combination of thermodynamic tools and quantum metrology, a science dealing in ultra-precise measures for quantum systems.

The physicists went on a search to determine the greatest possible precision that they could attain in a real situation. At present, it is extremely difficult to predict weather over the long term, why weather reports typically only offer the next ten days when describing temperatures and precipitation levels in a local region.

During their study, the researchers also realized that these new and improved thermometers are able to keep up a continuous degree of sensitivity while exposed to a wide range of temperatures if they shed just a small measure of precision. In the long run, this could mean predictions over a much larger amount of time, delivered with considerable accuracy.

Their study has been published in the latest issue of Physical Review Letters.
