The ability to make single photons is vital for quantum computers.

 The ability to make single photons is vital for quantum computers.

Controlling complex systems requires that system operators have complete knowledge of the system and its interactions.

The problem with error correlation in quantum computers is that the qubits and quantum systems are much more sensitive to outside effects than binary computers. The other problem is that the anomaly that causes a calculation error can also happen during the second calculation. Things like gravity waves are global anomalies that affect all quantum computers. And that thing means that all quantum computers can calculate wrong at the same moment.

The big problem is also that quantum computers are the only things that can check and find errors in another quantum computer's solutions. Binary computers make the same 45-year calculations that quantum computers can make in seconds. And that thing means that outside things like torrents of gravity waves can destroy all the results that the Quantum systems produce. And the problem is that those outside effects can cause anomalous functions in all quantum computers in the world.

Things like changes in the gravity fields on Earth can also affect qubits. And that means the portable quantum systems might need information about the gravity field's strength so those quantum systems can calibrate themselves.

The system can make bubbles in quantum fields or qauntum layers using photons. Those things can help to transport information between superpositioned and entangled photons and electron switches.

The next-generation quantum computers require very good, and very accurate ability to control multi-state and multi-layer systems.

The next-generation quantum computers can use multiple multi-state qubits. Those qubits can be networks of triplons. And systems that can create photon pairs. The photons are between those electrons in quantum magnets, called quantum triplons. And that system can make more powerful and portable quantum computers possible. The network of superpositioned photons and electrons is extremely difficult to handle. The system must have the ability to create single photons that it can put between those electrons.

And then information must be transported from those electron pairs to the sender photon, which is in quantum entanglement and superpositioned on the receiving side. The ability to make photons interact with wave movement makes it possible to stop photons at the precise point between electrons. Then the system must drive energy to that photon so that it can create superposition and quantum entanglement with some other photon.

Then the energy level of the transmitter side of the quantum entanglement will rise higher than that of the receiving side. And the system can start to drive information into that system. The receiving part just pulls energy away from the receiving side. The key element in quantum systems is that the transmitting or active side in superposition must be at a higher level.

If superpositioned and entangled particles are at the same energy level, standing waves between those particles push them away. The electron pairs can transmit energy away from the receiving side, which helps to keep the difference in energy levels in superpositioned and entangled particles.

The ability to create lots of single photons allows the system to replace photons that flew away when the quantum entanglement reached the same level. The network-based, ultra-small systems are extremely complicated to handle. The system might have multiple quantum states, like photon and radio wave states. The system must know precisely the energy level of the qubits before they can transport information.

Things like gravitational waves and even differences in Earth's gravitational field make it possible that there are differences between real and calculated values in qubits. That thing destroys the information that the qubit should transport because the receiving system doesn't know at what level or state the system loads the information.

The quantum computer is 45 years faster than any binary computer. That is both the biggest opportunity and the biggest weakness in quantum computing. Only another quantum computer can check the calculations that those extremely powerful systems can make. Of course, it is possible to perform the calculation twice. However, the problem is that there could be some anomaly that cannot be predicted during the second calculation. Things like gravitational waves that can shake the qubits are collective anomalies. They affect all Quantum computers at the same time.
