Universal fault-tolerant quantum computing relies on the implementation of quantum error correction. An essential milestone is the achievement of error-corrected ...

The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness. Unlike binary bits of information in ordinary computers, “qubits” consist ...

In February 2019, JQI Fellow Alicia Kollár, who is also an assistant professor of physics at UMD, bumped into Adrian Chapman, then a postdoctoral fellow at the University of Sydney, at a quantum ...

Error-correcting codes form the cornerstone of reliable modern communications, ensuring that digital information survives noise, interference and channel imperfections. Building on Shannon’s channel ...

Error-correcting codes form the backbone of reliable digital communication by introducing structured redundancy to transmitted data, enabling the detection and correction of errors induced by noise, ...

How do you construct a perfect machine out of imperfect parts? That’s the central challenge for researchers building quantum computers. The trouble is that their elementary building blocks, called ...
