论文摘要
在过去的几年中，量子计算一直在提出重大发展，揭开了量子数量越来越多的系统。但是，通用量子计算机中不可靠的量子过程仍然代表要克服的最大挑战之一。这种障碍具有噪音操作以及与环境的相互作用，从而引入量子系统的腐蚀性。在本文中，我们验证了称为Swap Test的工具是否能够识别破坏性。我们的实验结果表明，掉期测试可以用作完整量子过程断层扫描的替代方案，只要引入了一些修改，就可以不破坏正在测试的量子。
Quantum Computing has been presenting major developments in the last few years, unveiling systems with a increasing number of qubits. However, unreliable quantum processes in universal quantum computers still represent one of the the greatest challenges to be overcome. Such obstacle has its source on noisy operations and interactions with the environment which introduce decoherence to a quantum system. In this article we verify whether a tool called Swap Test is able to identify decoherence. Our experimental results demonstrate that the Swap Test can be employed as an alternative to a full Quantum Process Tomography, with the advantage of not destroying the qubit under test, under certain circumstances, as long as some modifications are introduced.
