Exeter University scientists found that nano-sized thermometers that measure the temperature of tiny objects, can suffer from the effects of Heisenberg’s uncertainty principle. In the result of the quantum fluctate the device will be in a superposition between different measures of temperatures, making them similar to Schrodinger’s cat. About it reported in a press release on EurekAlert!.
The cat (original cat) is a creature from a thought experiment Austrian scientist Erwin schrödinger. The animal is in the box, and find out its status (alive or dead cat) by opening it. In application to quantum mechanics this means that the process of measuring (opening the box) allocates one of a plurality of States of the cat (dead or alive). Before the measurement the cat is not considered to be alive and not dead — he is imposing (superposition) of these States.
According to scientists, under certain conditions, the indications of thermometers would be subject to quantum effects and, like Schrodinger’s cat will be in a superposition of two different temperatures, for example at 90.5 and 89.5 degrees Celsius. The researchers hope that the results will help you to create the exact nanothermometer, taking into account the principles of uncertainty.
