Princeton University (Princeton University) and the University of Texas at Austin (University of Texas at Austin) A team of scientists recently announced that they have found a mysterious 马约拉纳费米 child (Majorana fermion). Before scientists had been searching for nearly 80 years!
马约拉纳费米 child was first by the Italian physicist Ettore? Maiorana (Ettore Majorana) forecast in 1937. This particle is unique because it is the only particle has both matter and antimatter properties.
Scientists took only 48 years to find the Higgs boson (Higgs Boson). But until 2001, no one really knows how to find 马约拉纳费米 child, which is why scientists have spent nearly a century of time to find it.
In fact, surprisingly stable马约拉纳费米promoter, but it is also extremely elusive.
Usually when they come into contact with particles of matter antimatter counterpart, the result is a powerful explosion of energy. Some people believe that antimatter annihilation would be to provide energy for the rocket and spacecraft good way. Thus, one might think, if both have the characteristics of a particle of matter and antimatter, it will be extremely unstable. However, 马约拉纳费米 child is not the case.
Because 马约拉纳费米 child has two conflicting traits, it rarely with the external environment influence each other. This makes them difficult to detect. This also means that if the scientists found that the new particles can, quantum computing will achieve a further significant progress.
Different from traditional computers, the data qubit quantum computer (quantum bits) transmission. The quantum state of qubit rendered, they can be both 0 and 1. The problem is difficult to find a scientist can not easily act as qubits simultaneously interact with nearby substances – such interaction would destroy the quantum system – the particles. But 马约拉纳费米 child can solve this problem.
To observe this elusive particle, scientists had to use a large (two-story) of the microscope. The microscope is now located at Princeton University’s Judd temperature Hall (Jadwin Hall) in.
“If you want to find such particles in a material, you have to use such a microscope, it allows you to see the exact location of the particles in the material inside.” Princeton University professor Ali? Ya Dani (Ali Yazdani) in a press release said.
Higgs boson in particle accelerators were observed, while 雅达尼 and his team wanted to see 马约拉纳费米 child in a practical material. This idea has an important reason.
“This is more exciting, but the practice is actually beneficial.” 雅达尼 said at a news conference, “because it enables scientists to exotic particles for quantum computing such practical applications.”
Theoretical calculations have shown that for many years, if 马约拉纳费米 child exist, they will appear at the opposite ends of a material.
The team used the material is ultra-pure crystals of lead. Scientists are full of iron atoms in the crystal in this, and let them form a single wire. In freezing conditions minus 457 degrees Fahrenheit, 马约拉纳费米 child at both ends of the wire to form.
