Quantum computing, sensing, and communications are emerging technologies that may circumvent known limitations of their existing traditional counterparts. While the promises of these technologies are currently narrow in scope, it is possible that they will broadly impact our lives by revolutionizing the capabilities of data centers and medical diagnostics, for example. At the heart of these technologies is the use of a quantum object to contain information, called a quantum bit or qubit. Current realizations of qubits exist in a broad variety of material systems, including individual spins in semiconductors or insulators, superconducting circuits, and trapped ions. Further advancement of qubits requires significant contributions from materials science in areas of materials selection, synthesis, fabrication, simulation and characterization. Here, we discuss some of the needs and opportunities for contributions to advance the fundamental understanding of materials used in quantum information applications.

量子计算，传感和通信是新兴技术，可能会规避其现有传统技术的已知局限性。尽管这些技术的前景目前范围很窄，但是它们有可能通过革命性地改变数据中心和医疗诊断功能来广泛影响我们的生活。这些技术的核心是使用量子对象来包含称为量子位或量子位的信息。量子位的当前实现存在于各种各样的材料系统中，包括半导体或绝缘体中的单个自旋，超导电路和捕获的离子。量子比特的进一步发展需要材料科学在材料选择，合成，制造，模拟和表征领域做出重大贡献。这里，
