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
IonQ (NYSE: IONQ), a leader in the quantum computing industry,
today announced a new breakthrough towards running large
applications on near term quantum systems using partial error
correction. The technique is an order of magnitude more efficient
than the best error correction techniques known today.
In a recent paper, IonQ researchers describe a novel way to
reduce noise in some of the most common and noisy operations used
in quantum applications, called Clifford gates. The partial error
correction scheme known as Clifford Noise Reduction (CliNR) uses a
modest 3:1 qubit overhead, compared to other techniques that
require tens, hundreds or even thousands of qubits for error
correction.
“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 Peter Chapman, President & CEO, IonQ. “The
achievement represents a significant step forward in IonQ’s efforts
to deliver on performance, scale, and enterprise-grade solutions to
solve customers’ most complex problems with our quantum
systems.”
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.
IonQ is also a leader in error mitigation, a technique that uses
software to reduce errors in quantum applications. Error mitigation
is commonly used by quantum computing companies, but has drawbacks
at scale as it requires many data samples for implementation,
increasing the time to solution.
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. IonQ plans to begin offering partial
error correction as a feature on its forthcoming IonQ Tempo system
generation.
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, IonQ and Deutsches
Elektronen-Synchrotron (DESY) announced initial results from its
study of initial results of their work to use quantum computers to
optimize flight gate assignments at busy airports. In June, IonQ
launched an accelerated technical roadmap focused on delivering
quantum systems with superior performance, scalability, and
enterprise readiness.
