Researchers at Swansea University in Wales, U.K., led an international team in demonstrating that conventional ion-trap technologies are suitable for building large-scale quantum computers.
Modern quantum computers still fail in running complex computations because of environmental noise and errors. "By using quantum error correction, we can respond to this challenge better," says Rainer Blatt of the University of Innsbruck in Austria.
The new technique exploits quantum mechanical properties for error detection and correction, and the researchers predict if they can keep the noise below a certain threshold, they can build a quantum computer that can perform quantum computations of arbitrary complexity by increasing the number of entangled quantum bits accordingly.
However, in order to achieve that goal, the capabilities of the technological platforms have to be optimally exploited.
The researchers introduced new variants of fault-tolerant protocols and found that a new generation of segmented ion traps offers ideal conditions for the process.
