Researchers created curved spacetime in the laboratory.

"Curved spacetime is a concept in the theory of general relativity, proposed by Albert Einstein, which describes how gravity affects the shape of the universe. It suggests that the presence of matter or energy in the universe causes the fabric of spacetime to curve and bend". (ScitechDaily.com/Cosmic Simulation: Researchers Create Curved Spacetime in Lab) 

Researchers created simulated black holes and curved spacetime by using Bose-Einstein condensate. The idea of this research is. To make energy flow into a very cold point. Similar way as it flows into a black hole. And then they can research the curvature of spacetime. 

The image above is a curved spacetime model. All gravitational fields form a funnel in spacetime. When the gravitation turns stronger it pulls the funnel longer. And the thing that makes time dilation in that funnel is that the particle that drops in the strong gravitational field's center galls that funnel longer than in the weak gravitational field. 

In this model, kinetic energy is energy, that travels from the gravitational funnel to the particle. And that thing makes particles remain longer. That is one way to explain time dilation. But then we can think about the Bose-Einstein condensate. The thing that makes this type of superconductor interesting is that they can use to make simulated black holes. 

 Bose-Einstein condensate can also use to create a thing called zero-point energy. 

Zero-point energy is not energy from nothing. It's energy that travels at a certain point. Zero point energy means the system, where in the middle of the system is the material like liquid helium or Bose-Einstein condensate in minimum energy level. The temperature of that material is as low as possible. 

That thing makes energy flow at that point. If there are some antennae like a graphene layer or 2D copper layer near that object. Energy flows through that layer. The atoms of that layer will capture that wave movement. 

This thing should make a very powerful energy source, but the thickness of the antenna is difficult to determine. If the antenna is too thick. The zero-point system cannot pull energy through it. 

And especially the collector antenna's size and density determine that system's power. The power of that system depends on how much energy it can collect. But still today, this type of energy source is theoretical level.

The digital "demon": how to increase the quantum computer's power? (Part2)

The key element in qubit is how users can be sure that its value is zero before the system starts to transfer data to it. The normal way is to decrease the temperature of the qubit to zero kelvin. In fact. That thing is probably not necessary in the future. 

The system can take any temperature or energy level to zero point. The zero point could be, for example, 20 degrees Celsius. 

The zero point is the point. Where the system starts to transfer data to the qubit. The problem with high-temperature qubits is how to control their oscillation. But if the system can keep the energy level stable that thing can revolutionize quantum computing. When zero-point is determined. The system can make superpositions and entangled pairs of elementary particles. 

And then the system will operate for a while. The problem is that the energy level between both ends of quantum entanglement must not be the same. 

If the energy level of superpositioned and entangled particles is the same. That thing breaks the quantum entanglement. The reason for that is when both particles reach the same energy level the wave movement that they send pushes those particles away from each other. 

That means the time that the system can keep quantum entanglement is limited. So if we return to Maxwell's demon model we can maximize the time that quantum entanglement remains by using the simple thing. We can put another side of the quantum entanglement to a minimum energy level. 

And the other side will rise to maximum energy level. When the difference between energy levels of both sides of quantum entanglement is very high, that maximizes the time that the system can maintain the superposition and entanglement. 

But then we can increase the quantum computer's power by using the model where the zero point of the qubit is determined individually in each case. The system can determine the zero point as an example to 20 degrees Celsius. But then the system must keep the energy level or temperature of the qubit stable. 

The problem is that the hot or warm qubit must not oscillate. So the system must protect the qubit. Or the data will not keep its form. The problem with high-temperature qubits is the oscillation. 

But other ways. As I wrote earlier, the system can determine any temperature or energy level to zero point. If the system can keep the oscillation of the qubit in its form that can be a revolutionary advance in quantum technology.
