IonQ Invents a Novel, Low-Overhead Approach for Partial Quantum Error Correction
Represents significant step towards error correction, enabling faster, more accurate quantum applications with near term computers
In a recent paper,
“This cutting edge innovation on error correction led by IonQ’s research team offers the potential to supercharge the accuracy of near-term quantum computers, bringing us much closer to commercial advantage,” said
Error correction–the practice of using many physical qubits to constitute a more accurate logical qubit–is an important milestone for quantum computing, but one that is believed to be several years away given the large overhead of qubits and quantum gate operations required to achieve it. Currently, IonQ’s high fidelity trapped-ion qubits enable error correction overhead ratios as low as 13:1, but even these ratios consume too many qubits to be practically useful today.
The CliNR technique offers an exciting alternative to full error correction and error mitigation, balancing qubit count and time to solution. It employs an efficient overhead of three physical qubits for each error-corrected qubit and requires only a modest increase in quantum gates to calculate a more accurate solution. Results simulated using the CliNR technique demonstrated a substantial fidelity improvement when compared to applications run without error reduction techniques, and were suitable for applications using up to 85 qubits.
Partial error correction could be a critical driver in achieving exponentially deeper quantum circuits to run increasingly complex algorithms for customers.
The invention of the CliNR technique is the latest in a series of technical and applications advances pioneered by IonQ’s world-class research team. In March,
