Quantum Network

 

With the discovery and development of quantum mechanics, the first quantum revolution has been implemented quickly over time. In the first quantum revolution, we can give examples of technologies such as superconducting and laser that we are mostly familiar with now.

However, II. The quantum revolution has also begun to be developed rapidly. II. The fields that make up the quantum revolution are quantum computers and information. In my previous articles, I mentioned quantum quantum computers, teleportation, and cryptology as a start. Today's article will be about the quantum internet.

The quantum internet uses the principles of superposition and entanglement, which, like quantum computers, involve strange properties of the quantum. The underlying logic is the same as the entangled qubits that underpin quantum computers. It is aimed to convey the information in this way by transmitting the entangled qubits that form it between the quantum devices.

Do not think that we can use the quantum internet as casually as the classical internet on a daily basis. Because, as you know, after creating quantum entangled states, transmitting them to very long distances without deteriorating the states and losing efficiency is a very difficult problem in terms of engineering. External factors such as temperature and pressure are the main sources of these problems. Since even fiber optic cables to transmit entangled photons difficult for the quantum internet to reach the desired point, China launched a quantum internet satellite into space in recent years and brought a new approach to studies in this area. It seems that we will not be able to use the quantum internet like the classical internet in the very near future. Of course, rapid scientific developments can reverse this situation.

So what advantages can it offer us with the development of the quantum internet?

For example, the GPS devices we use all the time will become more precise, detailed mapping of the Earth's gravitational field, higher resolution simulations thanks to the quantum internet running on quantum computers, and thus simulating complex probes such as molecules and proteins or in all fields of science and engineering can be provided.

Bloch Sphere – Geometric Representation of Quantum State

    It is very difficult to visualize quantum states before our eyes. The Bloch sphere represents quantum state functions quite well. The Bloch sphere is named after physicist Felix Bloch. As you can see in the Bloch sphere figure below, it geometrically shows the pure states of two-level quantum mechanical systems. The poles of the Bloch sphere consist of bits |0⟩ and |1⟩. Classically, the point on the sphere indicates either 0 or 1. However, from a quantum mechanics point of view, quantum bits contain possibilities to be found on the entire surface of the sphere. Traditionally, the z-axis represents the |0⟩ qubit, and the z-axis the |1⟩ qubit. When the wave function in superposition is measured, the state function collapses to one of the two poles no matter where it is on the sphere. The probability of collapsing into either pole depends on which pole the vector representing the qubit is closest to. The angle θ that the vector makes with the z-axis determines this probabilit...

Statement of Bell's Inequality

 One of the most important applications of quantum mechanics is Bell's inequality. In 1965, John Stewart Bell actually thought that Einstein might be right and tried to prove it, but proved that quantum logic violated classical logic. It was a revolutionary discovery. Let's look at its mathematically simple explanation. To create the analogy, let's first write a classical inequality.   This inequality above is a classic expression. The quantum analogy of this expression represents the Bell inequality. With just one difference. Bell's inequality shows that the above equation is violated. Expressing Bell's inequality by skipping some complicated mathematical intermediates; While there is no such situation in the classical world that will violate the inequality we mentioned at the beginning, it is difficult to find a situation that does not violate this inequality in the quantum world.

Let's Define Quantum Programming

    Along with the strange discoveries of quantum physics, one of these ideas for how we could use it is quantum computers. Work on quantum computers, which is a pretty good idea, started small and became what it is today. Now we had to take one more step and do quantum programming. The first studies on this process were made in the early 2000s. However, these studies were more theoretical. This was because quantum computers were not yet technologically ready. Finally, with the serious development of quantum computers (of course, we are still not at the desired point) we started to create our quantum algorithms. Today, we can do these algorithms on IBM Quantum Experience, Microsoft Azure Quantum, DWave Leap Cloud, or with quantum development kits. With these platforms, most of which are open source, we can create our quantum algorithms with the Python language, which we use classically and which is the most common programming language. The fact that such platforms are open sou...
