Fault-Tolerant Operation of a QuantumError-Correction Code


Kenneth Brown: The @bacon-@PeterShor1 code project has been a great collaboration with Chris Monroe's group @JQInews and my group @DukeEngineering @DukePhysics @GTCSE. It is an amazing experiment with excellent control over 13 ions in a chain of 15 ions. Here is a thread about the theory. 1/n

Ion busters: Everyone welcome the #LogicalQubit (achieved with #TrappedIons nonetheless). The paper shows that the logical qubit's coherence exceeds that of individual ones. An incredible experimental achievement by @JQInews including @crystalMIT13 @kenbrownquantum.

James Wootton @ home: In a talk a few days ago, I said that this milestone had not yet been reached but would be soon. Little did I know how soon!

Robert Niffenegger Ph.D.: Wow, trapped ions are really starting to run away with this QC thing... FT Operation of a QEC - Amazing! @crystalMIT13 @kenbrownquantum Shout out to @M_Labs_Ltd ARTIQ. No way you could tune these gates with (*horrified look*) labview!

holevo bound boy: So, I’ve been seeing a lot of people attribute this paper to IonQ - thank you but this was Duke and JQI, not us! We take a lot of inspiration from their system but ultimately this achievement belongs to them.

NΩ⚛Name🍺: "These results show that fault-tolerant QC systems are currently capable of logical primitives with error rates lower than their constituent parts. With the future addition of intermediate measurements, the full power of scalable quantum error-correction can be achieved" Hedge👇

Brendan Reid: "With the future addition of intermediate measurements, the full power of scalable quantum error-correction can be achieved." Results like this make me think the 5-10 year timeline for useful QCs is more than achievable.
