This Superconducting Material Could Power Quantum Computers

So far, what quantum computing has been doing is undeniable. Quantum computers can perform highly complex calculations in a short time with high accuracy. Although its technology may be limited to some areas, recent research from John Hopkins University published in Science has opened the door to a new frontier of quantum technology.

Compared to conventional computing, quantum technology is capable of processing data at a faster rate. They also use qubits, or quantum bits, which are a superposition of 0 and 1. An example of qubits is Schrodinger's cat, a famous hypothetical experiment that applies to quantum theory. 

The author of the research, Yufan Li, mentioned the team's finding of a superconducting material including distinct properties that can be used as tech-building blocks in the future. Specifically, a β-Bi2Pd ring that exists among two states without magnetic fields can make it become a qubit.

For now, the focus of the researchers is the Majorana fermions. These are particles that act as their own antiparticles with opposite physical charges and equal mass. Despite being capable of storing large amounts of quantum information, they do not exist in a natural way. Scientists in another study also realized the presence of topological superconductivity, which is an indispensable physical state for durable quantum computing. 

Regarding topological superconductivity, it is a state where two electrons from one of every three pairs automatically form their spins in a triplet superconductor. Though the theory has proved, scientists have yet to discover a superconductor that can manipulate the Majorana fermions. Once scientists successfully manipulate particles, error-free quantum computing will be sooner developed and bring quantum technology to a new level.

The applications of quantum computing for complex fields are unlimited, such as artificial intelligence, cryptography, weather forecasting, drug development, and financial modeling. Such research will help enhance quantum technology to a further level, beyond what it can achieve now.
