New quantum matter can conduct electricity at nearly the same speed as light

Scientists are trying to make the dream of quantum computers a reality.

Physicists are still testing two-dimensional quantum materials that can "overthrow" the king of graphene - the marvelous material of the future.

These new parcels can transmit fast electricity near the speed of light, replacing silicon in future electronic devices. Even one of those materials creates a new "superconductor" , capable of breaking both the symmetry of time or reversing the whole time line.

"In the end, we can bring the superior theories of physics to create something useful , " said one of the researchers at the University of California, Jing Xia.

"We are exploring the ability to create quantum computers that are just theory at the present time."

Two researchers, Cheng Gong and Xiang Zhang are holding CGT material in their hands.

Xia and his team, along with many researchers from universities across the United States and China, have been studying the potential of some quantum materials that can revolutionize the computer manufacturing industry in next decade. The results of these studies have all been published in three reputable magazines, Nature, Science Advances and Nature Materials.

They pay much attention to materials that have both electronic and magnetic properties - properties needed for computer memory or any data storage system.

We have such a metamaterial, that is graphene. This two-dimensional carbon atom plate is extremely flexible, harder than diamond but more solid than steel, has great potential in conducting electricity but it has a large minus point: it has no magnetism, so no (or is not) can be used in computer manufacturing industry.

But that's when its relative - chromium germanium telluride (CGT) - speaks up. Using the world's most modern magnetic sensitive microscope called Sagnac , the team observed the microscopic structure of CGT and measured that it was only two atoms thick, the length and width were only a few. micron (1 centimeter = 10,000 micrometers). Human hair only has a diameter of 17 to 180 microns.

Thin structure of CGT.

When the material reaches a temperature of -233 degrees Celsius, the team confirms that they have added magnetism. The results of this experiment answered the question that ached about quantum physics, that magnetism could exist in materials that existed in two dimensions.

"This is an extremely interesting discovery," said researcher Xiang Zhang from the University of California research team. "This test gives us evidence of a magnet that is as thin as an atom, which will surprise many people."

Along with electrical conductivity, this material has proven itself in the future of quantum computer industry.

Use special adhesive tape to "peel" each layer of material out, creating the final product.

Among the materials studied, a quantum material is also a remarkable combination of bismuth and nickel. Specifically, when researchers put the two elements in contact at a temperature of -269 degrees C, they "form a superconductor that can break the symmetry reversal of time" . They have the ability to reverse the flow of time.

"Imagine that you turned the clock back and made the red tea cup dissolved into blue. Will that make the cup of tea extremely strange? This is also very strange when applied to another superconductor, " said Xia.

"This is the first time this factor has been observed on two-dimensional materials."

Now, knowing a little more about the capabilities of these quantum materials, we will have to find ways to apply them to reality, to turn those "potentials" into reality. All to reach a final destination with a quantum computer name.
