Discoveries can explain why magnetars have so strong magnetic fields.




"The study of the sound speed has revealed that heavy neutron stars have a stiff mantle and a soft core, while light neutron stars have a soft mantle and a stiff core – much like different chocolate pralines.

Even if neutron stars are rotating at extremely fast speeds. Sound travels in those extremely thick objects. Sound is an oscillation of atoms, subatomic particles, and molecules. And soundwaves are traveling in neutron stars almost like in all other particles. Except in neutron stars sound means the oscillation of the neutron's quantum fields. And that thing makes that thing very interesting. 

When the jet of another neutron star impacts with another neutron star it can put it to resonate. That resonance is possible especially if the neutron star's core is stiff. 

The light neutron stars have a soft mantle and stiff core. Heavy neutron stars have stiff mantles and soft cores. In the case of neutron stars, the "stiff" and "soft" are far harder than iron. The material of neutron stars is one of the strongest in the universe. Researchers are interested in that material because the 2D neutron network is called "neutron-" or "quantum graphene". 

Neutrons are polar particles that have north and south poles. And that thing makes it possible that neutrons can create a similar structure to graphene. 

The discoveries can explain why magnetar's magnetic field is so strong. Magnetar is a neutron star with a very powerful magnetic field. And the reason for that is the core of that neutron star orbits very fast. Magnetars are lightweight neutron stars. That allows their core can rotate faster than heavy neutron stars. 

That thing can explain what makes magnetars so special. The fast-rotating stiff core can like hover above the mantle. And the extremely fast rotating core is the reason why magnetar's magnetic field is so strong. There is a vision that magnetars can superposition with each other. In that case, the radiation from another magnetar synchronizes the resonation of their core. 

In some other theories, neutron stars can have two stiff cores over each other. That thing removes the friction between those cores. And the core of that theoretical model rotates over the quantum rolls. The neutrons of the lower core act like small rolls. That almost removes the friction from the structure. And that thing makes it possible that the speed of the core is near the speed of light. 

That kind of rotating core can simply push the photons away from it. Or the powerful magnetic or quantum field simply captures photons between electrons that are orbiting in that field. That kind of effect can turn this kind of neutron star almost invisible.

New ultra-thin materials are opening the road to personal quantum devices.



The ultra-thin materials are key for making the new type of hybrid quantum processors. The new material is the forming of one atom layer. And they are consisting of the channels where qubits can travel or they can anneal. The quantum annealing systems can be the extremely stable carbon crystal. Between one atom thin graphene or silicon layers. The problem with quantum computers is that the input system for data is problematic. 

Those systems must calibrate to operate in the quantum world. Normal keyboards and screens are using binary computing. And the problem is that the qubit is not similar to a binary computer. When we think that the qubit is like a hard disk that travels in the quantum tube. We can model that the qubit is the electron that has a minimum of three states. And there are let's say 10 accelerator lines or nanotubes where those electrons are traveling. 

So that kind of quantum processor has 30 states in the qubit. The system can benefit the nano-scale binary processors very effectively. In that case, there would be the nanotechnical binary processor at both ends of the nanotube. That means that every binary processor will operate with one qubit line. And that thing makes it possible to make the new smaller-size quantum computer. 


Superconducting copper wires can act as qubits. The qubit's state can determine by the voltage level in the wires. 





1) The input routes to 

2)Binary processors that are loading data to qubits

3)The route of the qubit

4)Receiver and decoder system. That system turns qubits back to the binary system.

5)The binary output to the screens and other output devices. 


The diagram above introduces the quantum processor that has four accelerator lines. There can be four-state qubits that are traveling in the quantum channel. The fact is that there is the theoretical possibility to make those quantum channels by using normal copper wires. 

The thing is that portable quantum computers have fewer qubit layers or states than some super quantum systems. So when we are trying to compare quantum and binary computers we cannot expect that our laptops can make the same things as some supercomputer. 

The superconducting electric wires can transmit electricity in the form where it is sent to that wire. The boxes are at the ends of the system. Are binary processors. That transforms data flow that comes from binary system to quantum mode. And then another binary system will decode them to screens and other output devices.
