A group of
physicists has discovered a new state of matter that can lead to significant
advancements in quantum computing and device storage. The state is called
topological superconductivity and can be utilized to tremendously speed up
calculations.

The
scientists focused their research on quantum bits (qubits), used to process
values in quantum computing. Rather than using 1s and 0s, they use properties
that can be found in a quantum system, like electron spin or a photon's
polarization. This approach is the promise of this type of computing,
significantly increasing the volume and speed of processing data.

Specifically,
the physicists looked to devise a way to employ Majorana particles or fermions,
which are their own antiparticles and can possibly store quantum information in
protected computation spaces, away from environment noise that leads to errors.

The new
state discovered by the researchers could be used to make appear such
error-free and stable particles, which don't have natural hosts, and use them
for computation.

The team
that included Javad Shabani from New York University and members of his Shabani Lab, Igor Zutic from the University of Buffalo, and Alex Matos-Abiague of Wayne
State University, looked and measured the transition between a regular quantum
state to the new topological state. The scientists are hopeful their find will
lead to major advancements.

"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," explained Shabani.
