A new type of quantum sensor can see inside atoms.

"Nuclear physicists have discovered a revolutionary way to use the Relativistic Heavy Ion Collider (RHIC) at the U.S. Department of Energy’s Brookhaven National Laboratory to gain insight into the shape and details of atomic nuclei. This method involves using particles of light that surround gold ions as they travel around the collider, as well as a new type of quantum entanglement that has never been observed before".

The superpositioned and entangled particle pairs can form a new type of quantum system. Those particle pairs can form the miniature doppler-radar that can detect things. That has been invisible before. The superpositioned and entangled particles can also use to scan subatomic particles and the atom's internal structures. 

The idea of quantum sensors is that they are acting like full-scale sensors. But the size of those sensors is far smaller than regular sensors. The thing is that theoretically two electrons or two superpositioned and entangled photons can form doppler radar antennas. In the same way, the line of hovering electrons can form the SAR radars. 

Doppler radar is two antennas that detect the change in radio waves. That system is one of the most common in use to measure an object's speed. Scanning doppler radar means the system there antennas are rotating each other.

"Left: Scientists use the STAR detector to study gluon distributions by tracking pairs of positive (blue) and negative (magenta) pions (p). These p pairs come from the decay of a rho particle (purple, ?0) — generated by interactions between photons surrounding one speeding gold ion and the gluons within another passing by very closely without colliding. The closer the angle (F) between either p and the rho’s trajectory is to 90 degrees, the clearer the view scientists get of the gluon distribution. Right/inset: The measured p+ and p- particles experience a new type of quantum entanglement". (ScitechDaily.com/New Type of Entanglement Lets Nuclear Physicists “See” Inside Atomic Nuclei)

"Here’s the evidence: When the nuclei pass one another, it’s as if two rho particles (purple) are generated, one in each nucleus (gold) at a distance of 20 femtometers. As each rho decays, the wavefunctions of the negative pions from each rho decay interfere and reinforce one another, while the wavefunctions of the positive pions from each decay do the same, resulting in one p+ and one p- wavefunction (a.k.a. particle) striking the detector. These reinforcing patterns would not be possible if the p+ and p- were not entangled.

The SAR-radar or synthetic aperture radar is the system that is put in the moving platforms. That thing allows us to create an antenna that's dimension is very big. And the SAR technology makes it possible to create very sharp images from targets because the radar scanner's accuracy depends on the size of the antennas. 

The scanning tunneling microscope can use as quantum radar. The idea is that. The researchers can replace ions, which hover above the layer with electrons or even photons. Two hovering ions can form the antenna for miniaturizing radars. 

In quantum technology, doppler radars can create by using two electrons that hover above the layer. The wave motion that is sent to those electrons can turn them into the smallest doppler radars. That ever created. Series of small needles that hovers series of electrons that can scan layers with incredible accuracy. 

But also, there is the possibility to use superpositioned and entangled electrons or photons. Then the atom will transfer between those superpositioned and entangled particles. The superpositioned and entangled particle pairs can also use miniature doppler or SAR radars. And that kind of system can revolutionize radar technology.

Researchers made two entangled light beams. And that is a breakthrough in long-term and long-distance quantum communication.

"Researchers using an optical parametric oscillator light source succeeded in producing two entangled light beams. (Artist’s concept.)" (ScitechDaily.com/ Quantum Breakthrough: Light Source Produces Two Entangled Light Beams)

One of the reasons why quantum computers are under development is that they are hard to jam. Regular binary computers use the binary system. The binary system's model is the 2D data structure. Data, that is stored in mass memory. Forms of data allocation units. Those data allocation units can be bits or bytes etc...  (Bit or Byte is the size of the data allocation unit)

The problem with 2D data structure is this.  If two programs or event handlers (or data handlers)  try to touch the same unit this thing causes that system will jam. The event handlers cannot copy information from the same point to two different places. The problem is that in 2D data structure is that the data allocation units cannot go over each other. 

In quantum systems, data allocation units can go over one another. A qubit-form data allocation unit forms a 3D structure like a tower. So if two event handlers need to use the same data allocation unit. At the same time, they can touch the qubit from the data allocation unit in different places. In quantum systems, the qubit's layers or states' order is not as important as it's in 2D systems. If each state involves information that was its place in the qubit. The system knows how to remake the qubit. 

If we want to send information by using quantum networks we have one small problem. We must confirm the message that the receiver gets involving the same information, that the sender packed in the message. If something misses the sender must send the information again. The best way is to send the same message by using two routes. In that version, the system compares the information, that travels in both lines. 

The system can reduce the number of data units between those lines. And if the checksum is zero, that means data that travels in those data lines is identical. That thing requires the ability to make two identical superpositioned and entangled light or some other electromagnetic beams. If we think that we want to send information from point A to point B. And use this kind of technology. 

We must be sure that information doesn't travel through the same disturbance. If information travels through the same disturbance that can cause an identical error in the information package. So the system must send information back to the sender. And that verifies if the involvement of the information package is not changed. 

When researchers create more advanced and effective security methods. Those works have two purposes. 

1) Secure involvement of information package against eavesdroppers. 

2) Secure involvement of the information package against changes. 

The second purpose of security means. The information that the receiver gets identifies what the sender sends. So protecting the involvement of the information package is the prime purpose of security. 

Security is needed in long- and short-distance communication. The system must protect data when it travels in the system or between systems. The vulnerability can be fatal in the microchip's internal communication and communication between two systems. 

If the speed of systems is extremely high even short-term artifact effects cause very bad damage to the data packages. In mathematical calculations, even a small error causes wrong results. And in mathematics is only right and wrong answers.
