What would you do with photons which are in two positions at the same time?



"A view into one of the two vacuum chambers. Inside: the mount of the cavity (rectangular metal box). In the mount: two conically shaped objects in white. These are two cavity mirrors. The distance between the mirrors is 0.5 mm and the researchers trap a single rubidium atom between these mirrors. (Credit: Max-Planck-Institute of Quantum Optics)

In the (Physicsworld. com) is an article about photonic superposition. The experiments of Max Planck institute researchers have proven that The atomic cavity sees the same photon in the two positions at the same time. Or those sensors can see the same photon twice. 

The thing is that the same photon can be in two positions at the same time. That can happen without destroying the photon can be open new and interesting ideas in the mind of scientists. The effect has been seen in the optic fiber, and that thing can use to make extremely high-accurate sensors and delivering information in the long-range. Or even that effect can be seen in the short distances, that thing makes it possible to make ultra-secured qubit. 

The thing where the photon can position in two places at the same time can make the more compact and less sensitive quantum computers. The qubits can form in the optic fibers, which are like the guitar strings in the system. That thing can protect the data better than magnetic qubits. 

Those superpositioned photons can be used to make the qubits, which can be carried in the quantum USB stick. The vision is that the data is loaded in the photons, which are in the optic fibers. The data is stored in the photons. And if that process is done with doubled photons, that allows keeping the copies of those photonic qubits in the source system. Copying the data can happen by doubled photons. The photons that are stored in portable memory can stress by using doubled photons. Then those photons, what is in the portable system will double to the target system. 

Then the system can remove from the computer, and it can have an internal power source. Then that quantum USB, which can be the size of the briefcase or even bigger can double those photons in the targeted system. In the next step, the system can ask to verify the data from the source system by using those stored photons. The fact is that the size of portable quantum USB disks might be quite big. But the size of the systems turns more compact when technology advances.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low.  The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away.  When the box is filled with quantum gas and som...

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with t...

The interesting coincidence between USS Sea Shadow (1982) and CSS Virginia (1862)

Image I The interesting coincidence between  USS Sea Shadow (1982) and CSS Virginia (1862) Far away from its time is the thing, that you might notice when you see those two images. The upper one (Image I) is portraying the modern naval USS Sea Shadow (IX-529)(1) experimental Stealth ship, which was created by Lockheed-Martin, and the image below (Image II) is portraying the CSS Virginia (2), the ironclad from the Civil War Era. The thing why the hull of the CSS Virginia, what is ironclad from 1862 is that the ammunition of the cannons would not transfer their impact energy to the hull of the ship. And the reason why Sea Shadows hull has this form is that it should point the radar echo away from the hull.  The thing that I must say that CSS Virginia is far ahead its time because that structure is effective against the explosive ammunition, and the slanting armor of tanks like T-34 and Sherman have made them effective. But for some reason, the use of slanting ...
