Harvard: Quantum telescopes with teleportation


A team of researchers from Harvard recently published a study, which suggests that a complex theory of quantum physics could be used to create huge, high-resolution telescopes.

Astronomers of the future will be able to see the most remote areas of the universe via teleportation…

Technically, it is called "entanglement", from "entanglement", but it will act almost like a teleportation. How will it work? A pair of quantum particles will "engage" with each other in such a way that whatever happens to one particle will happen to the other, even if they are separated by any distance.Harvard

The idea is that with the help of quantum technology we can build very large telescopes. The largest telescope we have today is called the Extremely Large Telescope. The mirror is 40 meters and costs a billion dollars.

However, engineers use a different solution to reduce the construction costs of the telescopic giant mirrors: they add smaller mirrors to groups called arrays. Unfortunately, the larger the arrays, the greater the loss of data.

These telescope systems can be built with today's industrial limits.
Quantum engagement could change all of this, but, unfortunately, it takes a continuous stream of entangled photons in space. Despite recent discoveries, and our notion of quantum computation, the number of photons involved reaches numbers that we can not manage.

But what if there was a way to reduce the number of photons involved?

That's what the Harvard team did.

Their work shows that by exploiting a phenomenon called "quantum memory" the number of entangled photons required for the operation of the telescope of the future will be much lower.

According to the researchers:

The necessary rate of jam allocation is reduced by several orders of magnitude, which opens realistic prospects for the use of short-term quantum networks for each high-resolution display.

But the team says a telescope could be 30 kilometers long - 100 times larger than it is today.
As the work of the Harvard team reports further development - and advances in quantum hardware continue, it is now almost certain that the telescopes of the future will be larger, with higher resolution and less expensive materials.

This means we will soon see the quantum age of astronomy.
