Study seeks to define quantum compression

A study led by Oak Ridge National Laboratory researchers identifies a new potential application in quantum computing that could be part of the next computational revolution.

The study surveys techniques for compressing data generated by sensors in edge computing — which processes data at or near sensors — and compares classical techniques with quantum approaches, which are mostly in development. Compressing data saves storage space and network bandwidth.

Classical computing stores information in bits equal to 0 or 1. Quantum computing stores information in qubits, which can exist in more than one state simultaneously and can carry more information than classical bits.

“Classical data compression is pretty well defined, but not quantum compression,” said Sarah Chehade, an ORNL postdoc and co-author of the study with ORNL’s Ali Passian. “We wanted to identify where quantum compression stands as a new enabling tool for edge applications so we can start more conversations on a definition and standards.”
