More on quantum telepathy and communicating with the past and future. Is time travel already here?

The previous post involved a discussion with Artificial Intelligence, “Copilot,” in which I suggested using entanglement (Einstein’s “spooky action at a distance”) for faster-than-light communication.

Copilot responded, “While quantum entanglement does involve instantaneous correlations between entangled particles, it cannot be used for faster-than-light communication.

This is because the process of measuring one of the entangled particles does not transmit any usable information on its own.

I disagreed, and wouldn’t you know, today I read the following article (excerpts) in New Scientist Magazine, August 17th.

Existing quantum devices could be used to disrupt the stock market

Commercially available quantum technology could let stock traders coordinate decisions to buy or sell nearly instantaneously using a technique called “quantum telepathy” By Karmela Padavic-Callaghan,8 August 2024

Quantum technology could shake up the stock market. Traders working at distant stock exchanges could coordinate decisions to buy or sell nearly instantaneously by using entanglement to create a phenomenon called “quantum telepathy” – and all the quantum devices they would need to implement this scheme already exist.

This takes advantage of a counterintuitive phenomenon in which two quantum particles can influence each other instantaneously across large distances.

Now, independent researchers Dawei Ding and Liang Jiang at the University of Chicago in Illinois argue that this kind of quantum entanglement can be used to gain advantages in the stock market, using only devices that are already commercially available.

He and Jiang considered high-frequency trading where trades happen in as little as millionths of a second. In their mathematical model, a high-frequency stock trader named Zhuo operates on the New York Stock Exchange (NYSE) and NASDAQ. The data centres of these stock exchanges are 56.3 kilometres apart. Zhuo has a physical server at each data centre, each of which modifies its selling and buying decisions only based on local information it receives at that exchange.

For the two servers to coordinate decisions, however, one must contact the other. The fastest that information can travel between them is at the speed of light, which would take 188 microseconds, or enough time for dozens of trades to be made.

Ding says this delay could be minimised to just the time it takes to detect a particle’s state if the two servers coordinated through what he and Jiang have called quantum telepathy – it is also known as quantum pseudotelepathy, a term coined a few decades ago by physicist Alain Tapp, as there is no actual telepathy occurring.

The new scheme relies on a pair of entangled quantum particles, such as particles of light, with one at each server.

The quantum state of the two would be prepared so that interacting with one changes the other, as with everyday entanglement. The difference here is that the second particle’s resulting change of state maps onto a set of pre-programmed trading decisions.

For instance, if Zhuo wanted to hedge his bets, the entanglement could be prepared such that if a measurement of the particle at the NYSE returns a state that correlates with “buy”, a measurement at the NASDAQ server would find its pair particle in a state that means “sell”.

Devices that produce pairs of entangled particles can already be obtained from several companies.

Ning Bao at Northeastern University in Massachusetts says the first company to use quantum telepathy for high-frequency trading could destabilize the market, which, in his view, raises the question of governmental regulation.

“I think if you wanted to make a company to do this, you could do it within a year,” he says. “It has the potential to circumvent the spirit of the law without circumventing the letter of the law.”

While Ding is excited by how immediately technologically feasible this research is, he says that mathematical work remains to develop efficient algorithms to determine optimal quantum telepathy schemes for trading situations beyond the simple hedging example.

He hopes to work with real-world trading data and collaborate with researchers who specialize in related experiments to make quantum telepathy on the stock market a reality.

Yes, there is a law in physics that says information cannot be communicated faster than light speed.

Entanglement is not considered “information communication” because it begins randomly.

When you examine one particle, the other particle will instantly be affected.

So if particle “A” is UP, particle B instantly will be DOWN, no matter how far apart they are.

The problem is that you have no control over whether particle “A” is UP or DOWN. It’s random.

The workaround for this is to create a set of agreed-upon prior instructions (algorithms).

The above article’s instruction seems to have been, “If my particle is UP,  I’ll buy and you sell. You’ll know to do this because your particle instantly will be DOWN.”

Ding is talking about algorithms, which I call “dictionaries” because that is exactly how language is developed.

When you read the letters “s,” “e,” “l,” and “l,” you have been trained that those letters together mean “sell,” and your dictionary tells you what that word means.

Now, let’s take a situation where time is a huge issue — space exploration.

A radio signal between Earth and Mars takes between 4 minutes and 24 minutes, depending on where the planets are in their orbits.

If you think a Martian rover is about to fall over a cliff, your message telling it to stop will take light speed to get there — 4 to 24 minutes.

By that time, the rover could be at the bottom of a chasm.

What if you loaded a few trillion, trillion entangled particles — half into the rover and half into the home base on Earth — with these instructions:

1. If you are going or stopped, and we want you to do the opposite, we’ll queue you with one entangled particle.
2. If we want you to turn left, we’ll queue you with two entangled particles sent within one second of each other.
3. Turn right, is three entangled particles within one second.

See the pattern?

To communicate full messages, use entangled Morse code for rovers.

Telegraphers had the same problem when trying to communicate via wire. Any one click had no meaning in itself, but the context of clicks and pauses communicated meaning.

We can use the clicks and pauses that already exist in Morse code as our instant message to Mars or anywhere else in the universe.

In that way, we would communicate faster than light, which is exactly what the stock traders propose to do.

Now, what do we do about messages into the past and future?

Here’s the problem: The speed of light is the ultimate speed limit in the universe. This limit ensures that cause precedes effect, maintaining a consistent order of events.

If FTL communication were possible, it could lead to scenarios where an effect could precede its cause. This could create paradoxes, such as receiving a message before it was sent.

Thus, FTL communication implies some form of time travel.

For instance, if you could send a message faster than light, it might be received in the past, leading to potential paradoxes like the “grandfather paradox,” where actions taken in the past could prevent the sender from ever sending the message in the first place.

FTL communication could create causal loops, where an event is both the cause and effect of itself.

This could lead to situations where information or objects exist without a clear origin, challenging our understanding of causality and the flow of time.

Since entanglement has existed for billions of years, have we already been living with time travel and not realizing it?

What do you think?
