An IQC advance in quantum error correction using nuclear spins shows promise for use in hybrid quantum information processors.
In order to perform quantum computation, researchers must also implement error correction to overcome the effects of “noise” that disrupts quantum systems.
The IQC research team demonstrated a three-qubit error correcting code using the magnetic resonance of carbon nuclei in a single crystal (their results were published in Physical Review Letters).
The recent PhysOrg article features an interview with lead investigator Osama Moussa, a postdoctoral fellow at IQC, who explains the significance of his team’s work in solid-state nuclear magnetic resonance (NMR).
“We've shown that there is the control possible to perform error correction in solid-state systems where the information is encoded on nuclear spins," Moussa points out. "One could envision a variety of hybrid systems with nuclear spins as the primary information carrier, for which this work will hopefully be relevant."
