One step closer to creating quantum computer.


Some physicians at the Rice University have discovered a partial that will some day in the near future be used for a quantum computer. It is a new kind of a computer that uses quantum particles instead of digital microchips found in today’s computers. Scientists discovered a new method for making tiny device called a quantum spin Hall topological insulator that acts like a superhighway electron that represents the basis for creating quantum particles to store data. Today’s computers are based on binary system where data could use either zeros or ones in a system but thanks to quirks in quantum mechanics quantum bits could be both zeros and ones. It improves the computer’s functionality and overall performance. It could preformed some complicated calculations or it could be used for much effective code breaking, biomedical simulation and climate modeling. But there is one problem: quantum fluctuations can produce the loss of data encoded in quantum bits and this is commonly known as "fault tolerance". Physicians say that they don’t need lots of quantum bits because they would need roughly 30 that are equal to 1 billion transistors. They rely on topological designs that are more fault tolerant. But the real problem is how to put a stable pairs of particles,  called Majorana fermions, into a chip.
"We are well-positioned for the next step," Du said. "Meanwhile, only experiments can tell whether we can find Majorana fermions and whether they are good candidates for creating stable qubits."

  1. Be careful not to copy paste too much as this is not the point of writing a summary. You need to pick out the most important details and then write about it in a paragraph, using your own words. It's okay to have a quote if you really think it's important, but it is not critical to have.
