The strange phenomenon of quantum entanglement, in theory, can span not only space but also time. And then it becomes really confusing.- Salik.bizQuantum entanglement (otherwise - confusion) may well be called one of the most famous and most incomprehensible from the point of view of everyday logic of the effects of the microworld

Scientists in the United States have figured out how to test problems that are not yet available to humans. Scientists use the same method as police investigators in their dialogue with computers solving these problems. They "confuse" the interrogated, interrogate two cars separately, etc

Modern computers provide quite a lot of possibilities for simulating a variety of situations. However, any calculations will be to some extent "linear", since they obey clearly defined algorithms and cannot deviate from them

Scientists from Australia and France have subjected one of the most ancient philosophical questions about causation to a quantum experiment. Initially, the topic of chicken and eggs was proposed by ancient Greek philosophers to determine cause and effect

Let's see what's wrong with the theory of relativity. The foundation of the special and general theory of relativity consists of only two postulates:The universe is homogeneous.The speed of light is constant.But before moving on to such terms, let's turn to the history of genius

Not so long ago, physicists showed the first results of the QUESS mission and the Mozi satellite launched into orbit within its framework, providing a record separation of quantum entangled photons at a distance of more than 1200 km

The use of light particles, that is, photons, to convey information is by no means new. Photons have been used in a number of tests to determine the accuracy of quantum networks over long distances

Infrared light can increase Internet speed a thousand times A professor at the Technical University of Eindhoven presented a new method of transmitting data using infrared light, which is much more efficient than conventional Wi-Fi or even 5G

All our senses are formed in the brain

Giants in the airNo one was able to explain how the ancient druids established the multi-ton boulders of the most mysterious monument of Stonehenge. As on the other side of the planet, the inhabitants of the abandoned Easter Island in the ocean dragged and raised giant stone heads

Shiny golden scarab beetles with shells capable of reflecting light will help physicists create ultra-fast data transmission systems

It is said that the epiphany came to Albert Einstein in an instant. The scientist allegedly was riding a tram in Bern (Switzerland), looked at the street clock and suddenly realized that if the tram now accelerated to the speed of light, then in his perception, this clock would stop - and there would be no time around

For the first time, researchers have managed to record the quantum teleportation of qutrit - an analogue of a qubit, but with three possible states.Until now, quantum teleportation has only been achieved for qubits, albeit at impressively large distances

The laws of classical and quantum physics differ from each other, but it seems that scientists have finally found a way to bring them together.When it comes to the physical world, size really does matter. While “large” (from a grain of sand to a galactic cluster) objects obey the same set of rules that we know about from classical physics, “small” objects (atoms and particles) behave quite differently. It was

Perhaps, there is no person on the planet who, in one way or another, has not encountered the manifestation of static electricity in ordinary life: its source can be a woolen sweater, a TV, and even a plastic comb, combing which the hair literally stands on end

Scientists working with the Large Hadron Collider announced new evidence of its existence. With the help of the Large Hadron Collider, researchers managed to obtain new evidence for the existence of a record heavy boson, there is

Quantum mechanics represents a real breakthrough in science, allowing scientists to explain many phenomena at the level of atoms and subatomic particles. And it is not at all surprising that such a dynamically developing field of knowledge has had a huge impact on the modern image of reality

Scientists from the University of Syracuse have created an unusual technology that allows you to "freeze" water while it is boiling, which will allow in the future to understand how to make water boil in space and how to improve the operation of liquid cooling systems for electric

Scientists from Germany have shown that teleportation of information is possible not only at the quantum level, but also in the world of classical Newtonian physics, although it works somewhat differently than in the world of elementary particles

A breakthrough in the study of the properties of light could pave the way for the future of quantum computing. Researchers at the Swiss Federal Polytechnic School of Lausanne (EPFL) have found a way to determine how light behaves outside the constraints of wavelengths, which opens up possibilities for encoding quantum data in a science fiction-style holographic light array

Physicist Moti Fridman and colleagues at Cornell University, USA, were able to create a "hole in time" by manipulating the speed of light, Science News reports

In 1900, the British physicist Lord Kelvin said: “There is nothing new in physics to be discovered. All that remains is to make more and more accurate measurements "

I would like to see new technologies developed in Japan contribute to the development of society

Australian scientists were able to reduce the error rate in semiconductor qubits, the unit cells of a quantum computer, to a level of 0.04%. This paves the way for the creation of universal computers, physicists say in the journal Nature Electronics

Fifty years ago, smartphones would have seemed like completely magical computers

Russian scientists have found a way to create a quantum device that violates the second law of thermodynamics and has an efficiency of virtually 100%, according to an article published in the journal Physics Review A

Austrian researchers have developed a new method of entangling photons, with which it is possible to combine three photons at once, to increase the efficiency of data transmission in a quantum system and thereby get closer to efficient quantum teleportation

Physicists have demonstrated for the first time the process of quantum teleportation from one silicon chip to another. Their system, built on the principles of integrated optics, uses a combination of nonlinear photon sources and linear quantum circuits

The predictions of quantum mechanics are sometimes difficult to relate to ideas about the classical world

Researchers at Yale University have demonstrated one of the key steps in the architecture of modular quantum computers: the deliberate "teleportation" of a quantum gate between two qubits
