IonQ Targets Quantum Error-Correction Bottleneck With Single-CPU DecoderIonQ Says Sin
Quantum computing hardware and software company IonQ says it has developed a quantum error-correction decoder that runs in real time on a single conventional CPU, potentially reducing the classical computing overhead that can slow larger quantum systems. In simulations spanning up to 408 logical qubits, the company’s decoder added as little as 0.02% processing time under standard operating noise conditions.
Quantum computing gains its power through qubits, a special type of ‘bit’ that can have any of many states between the traditional binary on/off state of classical computing. The primary problem with qubits is that these ‘superimposed’ conditions that are neither on nor off are extremely fragile to environmental noise and very easily collapse, reverting to the binary state useless to quantum computing.
We call operational qubits ‘logical’ and the much larger number of additional qubits needed to find a collapsed ‘logical’ qubit as ‘physical’ qubits. The current solution is...
