Abstract

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. QEC needs to be very power-efficient since the power budget is limited inside of a dilution refrigerator for superconducting qubits. In this talk, we introduce an online-QEC algorithm and its hardware implementation with SFQ-based superconducting digital circuits. We also briefly discuss future prospect for a necessary simulation environment for fault-tolerant quantum computers.
