The main problem with a quantum computer is the input-output process. The computer or Turing's machine is useless without the ability to introduce information to the user. The quantum gate that is introduced above this text can make the communication between the quantum and binary systems more flexible.
There are three main problems with quantum computers.
1) How the system can transfer data between quantum and binary systems. That ability is required is that screens and keyboards are using binary systems. The quantum computer is used through binary systems that input and output data in and from the quantum systems.
2) Quantum computers are sensitive against outcoming effects like electromagnetic radiation. And even gravitational waves can disturb the quantum system.
3) Quantum entanglement stays only a short time. The quantum entanglement stays for about ten seconds. After that, the system must reform that thing.
That's why data must store in fast-operating quantum memory units until it can be driven back to a re-adjusted quantum system. Without that ability, quantum computers cannot handle long-term calculations.
Also, even if long-term quantum entanglement is possible. Data must be backup copied. The reason for breaking the quantum entanglement could be a sudden electromagnetic impact like an eruption of the sun. Or gravitational waves can break the quantum entanglement.
So how the quantum computers can be easier to use?
The single-photon source that paves the way for quantum encryption is an interesting tool. That thing makes it possible to make quantum computing much easier.
In that system, the data will load to single photons. That is launched into a quantum computer. And then those things will superposition and entangled. The single-photon source can use to transmit data to the single electrons.
That kind of vision is interesting. And the single-photon source can make it possible to transmit data in qubit form over long distances. For long-distance data transmission. Those information carrier photons must cover against outside effects. And in that information photons will load into the laser ray. And then the laser ray will transfer them to the receiver.
The lasers or photons can also derail electrons through graphene. The photon will push electrons between the graphene layers. Then the photonic interaction will pump the data from the electron to the photons that are the heart of quantum computers. And the data that those superpositioned and entangled photons are carrying will transfer back to electrons and then to graphene.
The quantum gate that suppresses the data from the multi-qubit system to one qubit will make it possible to create better interaction between binary and quantum systems. The system benefits the Rydberg atoms in its operations. And that thing can make the quantum computer easier to use. The new quantum gate can help to optimize the communication between qubits and binary systems.
There are many problems with quantum computers. One is noise or turbulence. Superpositioned and entangled photons are very sensitive against outcoming effects. And one way to increase the resistance of quantum computers is to increase the power of the quantum system.
A Quantum computer's radiation will push disturbing radiation away from the computer. Another way is to use some heavier particles like protons or electrons for making quantum entanglement.
The problem with those heavier particles is that they are reacting to magnetic fields. The new programmable quantum sensors also make it easier to separate the information from multi-stage qubits and transfer it to the binary system.
So the quantum entanglement must protect by using powerful magnetic fields. Those kinds of magnetic fields are used in the fusion tests. And they can make the points of the heavy-particle quantum entanglement stable.
