Original Abstract Submitted

a computing system is provided, including one or more processing devices. the one or more processing devices are configured to receive quantum circuit parameters including a code parameter of an error correction code and a number of t gates included in a quantum circuit. the one or more processing devices are further configured to receive respective decoder parameters of each of a plurality of candidate decoders. the decoder parameters include a physical noise rate of a plurality of physical qubits at which the quantum circuit is configured to be executed and a stopping time of the candidate decoder. the one or more processing devices are further configured to compute respective spacetime costs of the candidate decoders based on the quantum circuit parameters and the decoder parameters. the one or more processing devices are further configured to output a selection of a lowest-spacetime-cost decoder for implementation at a quantum computing device.
