In the regular session the stock of the Maryland-based company edged 0.57% higher to $40.74, according to Benzinga Pro data. The company announced the industry’s first end-to-end real-time quantum error correction decoder that runs on a single, standard off-the-shelf CPU. IonQ said the decoder was validated across benchmark circuits simulating 408 logical qubits and more than 31.5 million quantum operations, adding just 0.02% processing overhead. Nicolas Delfosse, IonQ’s quantum research lead and paper co-author, said: “Successfully validating real-time decoding across hundreds of logical qubits and over millions of logical operations is an important milestone.”

The announcement came one day after IonQ announced a multiyear hardware agreement with South Korea’s SDT, Inc. Under the deal, IonQ will supply a Superion 256 quantum computer and silicon vacancy quantum memory modules.
