Fault-tolerant Quantum Computing with the Color Code

One of the most significant obstacles for implementing quantum computing is noise, corrupting quantum information stored in qubits. Quantum error-correcting codes can be utilized to overcome this by distributing quantum information into multiple qubits. The color code is one of the representative error-correcting codes, which allows relatively straightforward implementations of logical gates. In this article, I describe how to perform fault-tolerant quantum computing using the color code, including correcting errors via decoding and implementations of logical gates.
