The next step in quantum technology is on the door. The photonic processor is coming. The difference between photonic processors and regular processors is in photonic processors photons transport information. There are three types of photonic processors.
1) Half photonic processors.
In those systems nano-size lasers transport information between processors' internal components. So only the processor's wires are replaced by laser rays. The photovoltaic cells transform information between photonic and electric elements.
2) All photonic processors.
In those processors, all information transportation happens in the photonic mode. These kinds of systems are more powerful than electric-based systems. They will not heat so easily, as electric-based systems. Photonic processors are also immune to electromagnetic fields. But the problem is how to control those photons.
In the wildest vision, the 2D structure in photonic processors is a network of superpositioned and entangled particles. That thing could make portable quantum computers possible. The problem is how to control the system. Full control of the system requires that operators can remove all non-controlled space and artifacts from the system.
3) Half-biological photonic processors.
In that model, the living neurons in neurochips are connected with microchips. In every single axon is a connected microchip. And data travels between neurons in that neurochip in photonic mode. That's why every single of those microchips is equipped with lasers. Laser- or photonic base data transmission is not so vulnerable to electromagnetic fields as electric communication.
The idea of the biochip that uses a combination of microchips and living neurons is not new. The biochips are planned to use to fix neural damage and train cloned neurons for futuristic neural transplants.

The requirement for successful quantum computing is that. The operators can perfectly control the quantum system. Without that ability, quantum computers are unable to operate. Or they are unable to make trusted calculations.
The major problem with Quantum computers is how they read information from the qubits. When a photon hits material it releases its energy. The key element in that problem is to aim for the photon that carries information precise right point. If some other photon or EM field affects the photon while it transports information that causes corruption.
The new theory or model about the material called "light-induced phrase" can help to model the quantum interactions between photons and material. And modeling the photonic interaction in the material is important for quantum computers.
