QECOOL: On-Line Quantum Error Correction with a Superconducting Decoder for Surface Code

Understand

Due to the low error tolerance of a qubit, detecting and correcting errors on it is essential for fault-tolerant quantum computing.

• Surface code (SC) associated with its decoding algorithm is one of the most promising quantum error correction (QEC) methods.
• % One of the challenges of QEC is its high complexity and computational demand.
• QEC needs to be very power-efficient since the power budget is limited inside of a dilution refrigerator for superconducting qubits by which one of the most successful quantum computers (QCs) is built.
