A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College and Santa Clara University.
Research describing the effect shows that superpositionthe ability of an atom to exist in more than one state at the same timeleads to a correction in atomic clocks known as "quantum time dilation."
The research, published in the journal Nature Communications, takes into account quantum effects beyond Albert Einstein's theory of relativity to make a new prediction about the nature of time.
In the early 1900s, Albert Einstein presented a revolutionary picture of space and time by showing that the time experienced by a clock depends on how fast it is movingas the speed of a clock increases, the rate at which it ticks decreases. This was a radical departure from Sir Isaac Newton's absolute notion of time.
Quantum mechanics, the theory of motion governing the atomic realm, allows for a clock to move as if it were simultaneously traveling at two different speeds: a quantum "superposition" of speeds. The research paper takes this possibility into account and provides a probabilistic theory of timekeeping, which led to the prediction of quantum time dilation.
To develop the new theory, the team combined modern techniques from quantum information science with a theory developed in the 1980s that explains how time might emerge out of a quantum theory of gravity.

So if a clock can move as if it was simultaneously travelling at two different speeds...
Does that mean I can strike out with 2 women at the same time in different parts of the same bar?
And if I make rude come ons, can I simultaneously have vodka AND beer thrown in my face in two different places at 2 different times by 2 different women in the same bar?

It’s very possible for gross matter to be in more than one state simultaneously too. DemocRATs, for example, are baby-killers, traitors and looting moochers; all at the same time.

Pink Floyd - Time Ticking away the moments that make up a dull day Fritter and waste the hours in an offhand way. Kicking around on a piece of ground in your home town Waiting for someone or something to show you the way. Tired of lying in the sunshine staying home to watch the rain. You are young and life is long and there is time to kill today. And then one day you find ten years have got behind you. No one told you when to run, you missed the starting gun. So you run and you run to catch up with the sun but it's sinking Racing around to come up behind you again. The sun is the same in a relative way but you're older, Shorter of breath and one day closer to death. Every year is getting shorter never seem to find the time. Plans that either come to naught or half a page of scribbled lines Hanging on in quiet desperation is the English way The time is gone, the song is over, Thought I'd something more to say. Home Home again I like to be here When I can When I come home Cold and tired It's good to warm my bones Beside the fire Far away Across the field Tolling on the iron bell Calls the faithful to their knees To hear the softly spoken magic spell Source: LyricFind Songwriters: David Jon Gilmour / Nicholas Berkeley Mason / George Roger Waters / Richard William Wright Time (2019 remix [Live]) lyrics © Universal Music Publishing Group, T.R.O.

It’s deeper than you think.
DemocRATs, for example, are baby-killers, and against the death penalty, traitors and loyal to communism, looting moochers, and support grossly profligate spending all at the same time.

Aww screw that. Chopin is the guy yer thinking of. Metronome? Eff you. Eat some rubato. The beat is whatever is right in the moment. . Altough Frydyryk would insist upon strict adherence to metronome markings. He was a bit of a dick, and fop, and anti-Semite. But he was a genius tunesmith and contrapuntalist.
