论文摘要
极大的兴趣围绕着开发新策略的发展，以有效地以强大而无腐烂的方式来存储和操纵量子信息。已经提出了一些建议，将信息编码为同时对放松和消除过程不敏感的Qubits。其中，鉴于它们的多功能性和高度控制性，超导量子位已在这个方向上进行了很大的研究。在这里，我们对实施新型超导电路的基本概念和思想进行了一项调查，并在硬件层面上具有内在的保护防御性。特别是，主要重点是多模式超导电路，范式示例是所谓的$ 0-π$电路。我们根据常规的约瑟夫森元素报告其工作原理和可能的身体实现，介绍了最新的实验实现，并讨论了制造方法和特征。
Great interest revolves around the development of new strategies to efficiently store and manipulate quantum information in a robust and decoherence-free fashion. Several proposals have been put forward to encode information into qubits that are simultaneously insensitive to relaxation and to dephasing processes. Among all, given their versatility and high degree of control, superconducting qubits have been largely investigated in this direction. Here, we present a survey on the basic concepts and ideas behind the implementation of novel superconducting circuits with intrinsic protection against decoherence at a hardware level. In particular, the main focus is on multi-mode superconducting circuits, the paradigmatic example being the so-called $0-π$ circuit. We report on their working principle and possible physical implementations based on conventional Josephson elements, presenting recent experimental realizations, discussing both fabrication methods and characterizations.
