New Study Shows How Superposition Can Impact the Timekeeping

timekeeping theory

How the timekeeping in high-precision clocks works or how it’s influenced, a new study answers. 

Superposition is known as a phenomenon of quantum mechanics. Researchers found that superposition can impact timekeeping. The effect also leads to a correction in atomic clocks, the “quantum time dilation.” But that’s not all.

The study takes into account quantum effects beyond the popular Einstein’s theory of relativity.

Here is what you need to know.

The Study’s Insights

Quantum dilation is a result of both Einstein’s relativity and quantum mechanics. It also comes with a new possibility to check fundamental physics at their crossing. 

Albert Einstein introduced in the early 1900s a revolutionary image of space and time by presenting the following idea: time experienced by a clock depends on how fast it can move. The conclusion is that as the velocity of a clock rises, the rate at which it thicks lowers. Einstein’s theory was a critical departure from Sir Isaac Newton’s knowledge of time. 

The team’s work

The team needed to develop a new theory, so it mixed modern methods from quantum data science with a 1980 approach that tells how time might come out of a quantum theory of gravity. 

Mehdi Ahmadi, a lecturer at Santa Clara University and part of the team, released a statement. He said:

“In our work, we predict corrections to relativistic time dilation, which stem from the fact that the clocks used to measure this effect are quantum mechanical in nature.”

Quantum mechanics, the theory of motion ruling the atomic realm, enables a clock to move as if it were at the same moving at two various velocities. Such a thing is known as a quantum “superposition” of speeds. 

The recent study followed that possibility and offered a plausible theory of timekeeping. As a result, the prediction of quantum time dilation emerged.
