Increased Storage and Enhanced Quantum Computing Through Topological Superconductivity
Scientists discover new state of matter
+ In their research, Shabani and his colleagues analyzed a transition of quantum state from its conventional state to a new topological state, measuring the energy barrier between these states. They supplemented this by directly measuring signature characteristics of this transition in the order parameter that governs the new topological superconductivity phase.
“Our research has succeeded in revealing experimental evidence for a new state of matter—topological superconductivity,” says Javad Shabani, an assistant professor of physics at New York University. “This new topological state can be manipulated in ways that could both speed calculation in quantum computing and boost storage.”
+ Here, they focused the inquiry on Majorana particles, which are their own antiparticles—substances with the same mass, but with the opposite physical charge. Scientists see value in Majorana particles because of their potential to store quantum information in a special computation space where quantum information is protected from the environment noise. However, there is no natural host material for these particles, also known as Majorana fermions. As a result, researchers have sought to engineer platforms—i.e., new forms of matter—on which these calculations could be conducted.
+ “The new discovery of topological superconductivity in a two-dimensional platform paves the way for building scalable topological qubits to not only store quantum information, but also to manipulate the quantum states that are free of error,” observes Shabani.
