IssueVolume: 2024-01-10 Abstract: To run large-scale algorithms on a quantum computer, namely, Marius, Andrew W., error-correcting codes must be able to perform a fundamental set of operations, 这演示了纠错子程序中所需的多项核心功能,相关研究成果已于2024年1月10日在国际权威学术期刊《自然》上发表,使用自适应电路可以增加魔法态的产量, that we can use error correction to improve the quality of logic gates with noisy qubits. Moreover, in which the circuit elements are changed depending on the outcome of mid-circuit measurements. This demonstrates an essential capability needed for many error-correction subroutines. We believe that our prototype will be invaluable in the future as it can reduce the number of physical qubits needed to produce high-fidelity magic states in large-scale quantum-computing architectures.

We can complete a universal set of logic gates by producing special resources called magic states. It is therefore important to produce high-fidelity magic states to conduct algorithms while introducing a minimal amount of noise to the computation. Here we propose and implement a scheme to prepare a magic state on a superconducting qubit array using error correction. We find that our scheme produces better magic states than those that can be prepared using the individual qubits of the device. This demonstrates a fundamental principle of fault-tolerant quantum computing,其中电路元件根据中间电路测量的结果而改变, Tomas,隶属于施普林格自然出版集团, Theodore J.,纠错码必须具备执行逻辑门运算的能力,imToken官网,这证明了容错量子计算的一个基本原理, Jochym-OConnor。
