Abstract

Quantum error correction (QEC) is fundamental for the realization of scalable quantum computers. In this paper, we present a novel approach to surface code implementation that reduces the overhead of physical qubits by a factor of two, while maintaining the same threshold error rate.

1. Introduction

Quantum computers promise to solve problems that are intractable for classical computers. However, quantum information is extremely fragile due to decoherence and operational errors. QEC provides a path to reliable computation by encoding logical qubits into a larger number of physical qubits.

2. Methodology

We propose a dynamic syndrome extraction scheme that adapts to the local error rates of the physical qubits in real-time. By utilizing real-time feedback loops and adaptive measurement schedules, our approach minimizes the idle time of qubits, thereby reducing the probability of errors occurring between operations.

3. Results and Conclusion

Simulation results show a significant improvement in the logical error rate for a given physical error rate compared to standard surface codes. Future work will focus on integrating this scheme with fault-tolerant logical operations.
