For the first time, researchers made an interaction between microwaves and optical photons by using quantum entanglement.

The quantum entanglement between optical photons and microwaves can make a bigger revolution in quantum technology than we even imagine. 

The critical point in the data transfer between quantum systems and qubits is the point where electricity must turn into qubits. At that point, the system drives information from the electric system to photons. The quantum entanglement between optical photons and microwaves can solve that critical problem in quantum computing. And it can make a bigger revolution in quantum technology than we even imagine. 

In some models, the quantum computer is the silicon plate. The optical photons pump information to that silicon and the photovoltaic phenomenon makes information travel in the system. The system might base the 2D silicon structure that is connected with nano-springs to the graphene. 

The problem with this kind of system is how to drive information to the system and out of it. Making quantum entanglement between microwaves and optical photons could solve this problem. The problem with silicon-based quantum systems is how to drive information in that system. The system requires extremely high accuracy. The interaction between photons and silicon is one of the most promising things in how to transform information between optical and electric forms. The system requires laser rays with the same diameter as electrons. 

The weak and the most critical point in quantum computing is when the system transforms electric impulses into qubits. When the quantum system transfers information between electric systems and optical systems. The information must not change. So that makes the quantum entanglement between microwaves and optical photons so powerful tool. The quantum entanglement guarantees that the information that travels between optical and electric systems keeps its form. 

The answer could be the system that looks like a scanning tunneling microscope. The photons are created by changing the energy level of the hovering electron that hovers between the silicon layer and the extremely thin stylus. Then those photons would trap in the frame called a photonic crystal. And after that, the microwave would input data to those trapped photons, that will interact with silicon atoms. 

The next breakthrough in quantum technology is that researchers made an interaction between microwaves and optical photons. That interaction means that microwaves can exchange information between photons. And that thing makes at least fundamental advances in quantum computing and other kinds of quantum solutions.

The next step in quantum technology is the photonic brain. 

The quantum entanglement between photons and microwaves can use to transfer information to optical photons and backward. And that is the thing, that can make artificial neurons possible. In artificial neurons, the light cables act as axons. And every single glass fiber in that photonic brain is an axon. The idea is that the laser ray can transfer information to extremely small photovoltaic cells. And those photovoltaic cells turn optical information into electric mode. 

That allows to use regular miniature routers to route information in the photonic brain. Those routers receive information in the form of laser rays in photovoltaic cells. And then the miniature lasers resend that information to the right route. In those photonic brains, every single optical fiber is the independent state of the qubit. 

Radio- or microwaves could use to create qubits. The idea is every single independent frequency is one state of the qubit. So that thing makes the revolution in quantum computing. If things like drone swarms can make quantum computing entirety where each radio channel is a unique state of a qubit, that thing is a full-scale revolution in that kind of technology. 

The ability to exchange information between optical photons and other electromagnetic frequencies makes it possible that the intelligence system can steal information even from the quantum systems. 

The ability to exchange information between optical photons and other electromagnetic frequencies also makes the revolution in intelligence technology. Using extremely thin microwaves makes it possible to steal information even from optical cables and even from quantum systems. The attacking system sends microwaves through the optical data transportation system. The defending system observes the energy level of the photons. 

So if the attacker knows the energy level that information exchange changes the attacking system can replace that lost energy. The problem is that the microwave must be at a lower energy level than the photon if it receives information. When energy moves from the photon to the microwave it decreases the photon's energy level. That makes the system detect the anomalous change in the energy level of the photons. 

And that tells the defender that somebody might steal information. That should cause changes in the plans what that information consider. But if the attacker replaces the lost energy and avoids harming information, the defender might not see that information is leaked into the outsider's hands.
