The future arrives and much faster than we think. Let’s do an imagination exercise, imagine, for a moment, to be able to send information from one point to another without the need for cables, Wi-Fi or traditional signals, more or less as something telepathy, right? Well, it’s precisely What scientists recently achieved at the University of Oxford: data teleportation between two quantum computers. Although it may look like science fiction or just news, the world
Although, let us lower media threshing, the transmission distance of this experience was less than two meters, but that does not matter, what matters is to have reached this stage of information sharing without need connections.
What is quantum teleportation and how does it work?
Today, it is a question of imagining, but imagine that you have two identical white crystal balls in different rooms, and if one of them moves one, the other will also move at the same time whatever the distance. This is what happens with quantum teleportation (it does not disappear from one place and appearing in another that many can imagine) but instead of crystal balls, we are talking about subatomic particles called qubits. These particles (qubits) can be “tangled”, which means that they form such a strong link that what happens in one is automatically reflected in the other, whatever their distance. It is as if they had an invisible and instantaneous communication line. Something similar, as we said, telepathy. This discovery is completely incredible.
Although it is not enough to transport people from one place to another in the blink of an eye, just share a lot of information in an ultra-secure manner.
Why is it important for computers?
Very simple, do you know the term “bits”? These are the smallest units we know in computer science, and they can only represent two values, 0 (which means deactivated, false or without signal) and 1 (which means on, true or with signal), and They cannot represent any number other than these two have mixed to create codes. Quantum computers, on the other hand, use qubits, which can represent 0 and 1 at the same time, and this happens thanks to a quantum superposition which allows them to process information at various super-rapid speeds.
But, so far, the connection of quantum computers has been very complicated because the information has deteriorated during the transmission. Now, this problem has been resolved, allowing computers to communicate without losing data, which could lead to the creation of a “quantum internet”, which is much faster and safer for everyone.
The discovery of Oxford
The news occurs because scientists have managed to teleport information from a qubit between two quantum computers with an 86%precision, which means that most of the data arrived intact even if some were lost along the way. To test the effectiveness of the method, they used a special algorithm called Grover algorithm, which allows you to search for data in quantum information databases. The results showed an efficiency of 71% !!
Although this may seem a small thing, the progress made by these scientists will be a turning point for future information transmissions. Who knows what the future quantum will bring? What is clear is that it is no longer a concept on paper, but a reality that also approaches.
