Quantum physicists say time travelers don’t have to worry about the butterfly effect




What if I told you that all of your favorite time travel films and books were actually made by big tech to take control of the time travel industry from the proletariat?

Think about it. Back to the future, the terminator, the time machine, All of these stories have a central theme where traveling through time is a dangerous thing that could destroy the fabric of our reality.

It’s called the butterfly effect. The big idea is that you get out of your time travel machine and accidentally step into an error. Because this beetle doesn̵

7;t exist … maybe a frog starves and dies. And maybe this frog should hop on the face of a saber-toothed tiger at just the right moment so that the cave person from whom our greatest leader will descend can escape death.

But you just had to travel, didn’t you? Well, because this beetle is dead, the caveman has not lived and our planet is a nuclear wasteland when you return to the “present”.

A team of scientists from Los Alamos National Laboratory recently performed a time travel simulation on IBM’s quantum computer. And they found that all of these Hollywood scareers are full of it.

According to a press release from the laboratory, one of the study’s co-authors, theoretical physicist Nikolai Sinitsyn, said:

On a quantum computer there is no problem simulating the opposite development in time or executing a process backwards into the past. So we can actually see what happens to a complex quantum world when we travel back in time, add small damage and return. We found that our world survived, which means there was no butterfly effect in quantum mechanics.

We cannot go back in time, but we can subsequently simulate how systems react to faults. And the reason why we can do this is quantum computers can travel back in time.

What makes quantum computers so special is that they can produce all results at the same time. In a classic computer, for example, we use binary bits to process data by turning resistors on and off. However, quantum computers use qubits. And qubits can be switched on or off at the same time. So if we want to solve a really complex problem, we can run it through a quantum computer and get all the answers at once, instead of having it run through a classic computer several times with different parameters to get different predictions when a result is uncertain .

This is a lengthy way to say that quantum computers can reverse engineer the past to determine exactly how things would have gone in a particular system if something else had happened.

This does not mean that we can finally solve the JFK attack. This version of the past is a closed system that we currently have no access to. However, we can create an open system and allow the quantum computer to access it by simulation so that it can determine the various ways in which things can evolve over time.

Take it quickly: The most interesting thing here is that the simulation itself functions as a quantum mechanical detector.

We know that classic systems suffer from the butterfly effect. Do not you believe me? Go back about 10 code commits and start changing things randomly. Then generate new code from the buggy version and see how this works for your next software build.

Sinitsyn and his co-author Bin Yan tested their quantum mechanical hypothesis using IBM’s cloud-based Q system. According to the Los Alamos press release:

To test the butterfly effect in quantum systems, Yan and Sinitsyn used theory and simulations with the IBM-Q quantum processor to show how a circuit can develop a complex system by using quantifiers with forward and backward causes and effects.

According to the researchers, the butterfly effect has no impact on the quantum world, so its existence can effectively determine whether a system is classic or quantum in nature.

We can safely assume that every form of time travel with a time shift of humans depends on quantum mechanics – unless we turn out to be binary constructs that are themselves caught up in a simulation.

And that means when we’re not in the Matrix, Marty McFly and John Connor were just propaganda to keep ordinary people from using time machines in our free time. Even Ashton Kutcher lied to us. Butterfly effect Schmutterfly effect.
