First time in history, the researchers control the electron's spin at room temperature. That thing makes it possible to create a new type of electric device. 

The system can turn electrons in the same position. And that makes them more effective data transporters. Electrons that are at the same position can form the powerful cathode ray. That thing can use in the new X-ray systems. That ability to turn all electrons to the same position makes particle accelerators more effective than ever before. 

Also, things like room-temperature quantum computers are possible. The ability to control the spin of electrons at room temperature opens new visions for quantum technology. This system makes it possible to store qubits in portable devices. Those devices would not need so powerful cooling systems. And the ability to carry data in the form of qubit means better data security. 

To break the quantum security. The attacker must know the energy level or the state of the qubit where each part of data is stored. So the system that opens the data must know the map or notes where it can find that data? And even if the attacker knows those things. The qubit is lost if its data is downloaded to the attacking system. 

Or even if the room-temperature quantum superposition is not possible. The ability to control the electron's spin makes it possible to create faster electronic components.

Multiple layers of superpositioned and entangled particles can protect the most in particle pair of the quantum computer system. 

In a quantum computer could be multiple layers of superpositioned and entangled particles. Those superpositions and entanglements act like the coaxial cable that protects the most in particle pairs. 

And only particle pair that has a purpose as a data transporter is the most in photon pair. Those photons are superpositioned and entangled. 

Other particle pairs' mission is just to protect those two superpositioned and entangled photon pairs. This kind of system can work like this: 

-The most out is the proton pair

-In the middle is the electron pair

-And the most in particle pair is the photonic superposition and entanglement. 

That photonic pair transports information in that system. And the other layers are protecting that particle pair. 

Also, photonic superposition and entanglement can transfer data to electron qubits. The idea is that if the quantum field around the electron looks like a whisk that photon pair can paint the data to each superstring of that qubit. That helps to transform qubits into the binary form of data. 

*********************************************************************

The ability to control an electron's spin can open the gate between binary and quantum computers. The electron can "paint" information to the qubit. And also electron that spin is fully controlled can download data from qubit to binary form more effectively than ever before. 

Those kinds of things are the details that are required for the "quantum PC" or quantum mobile devices. The portable quantum computers must not need a cooling system if they can make qubits and superpositions at room temperature. And the ability to control the spin of an electron is the thing that makes those things possible.
