论文摘要
我们提出了一个论点，即在$（1+1）$ d中使用Qudits胜于标量量子电动力学的优势。我们使用超出时间相关器来测量质量差距，这是来自振幅阻尼误差通道的噪声以及两个量子和Qutrits的普遍的Pauli通道分流通道的函数。对于确定质量的相同误差，QUTRIT模拟比量子模拟可以忍受10至100倍的门噪声。我们发现，在不久的将来，使用Qutrits可能会有20个每百分比的准确性，但使用Qutbits是不可行的。
We present an argument for the advantages of using qudits over qubits for scalar Quantum Electrodynamics in $(1+1)$d. We measure the mass gap using an out of time correlator as a function of noise coming from an amplitude damping error channel and a generalized Pauli channel decoherence channel for both qubits and qutrits. For the same error in determination of the mass, the qutrit simulations can tolerate 10 to 100x larger gate noise than a qubit simulations. We find that 20 per-cent accuracy on the mass gap could be possible in the near future with a qutrits but is infeasible using qubits.
