摘要
量子态是量子信息论研究的重点之一。近年来,随着量子信息处理技术的不断发展,量子态的制备和控制变得越来越重要。Werner态及isotropic态是量子信息理论中两类重要的量子态,其在非相对论量子力学的背景下得到了广泛的研究。本文主要讨论了两比特Werner态及isotropic态在相对论变换下的性质。结果表明,在相对论变换下,变换后的量子态仍保持原量子态的形式,且其相对参数在速度趋近于光速时不变。
One of the areas of quantum information theory’s concentration is quantum state.The production and control of quantum states become increasingly important in the past few years as a result of the ongoing development of quantum information processing technology.Two significant quantum states that are widely studied within the setting of nonrelativistic quantum physics are the Werner state and the isotropic state.In this study,the properties of the two-qubit Werner state and the isotropic state under relativistic transformation are mainly discussed.The results show that,under the relativistic transformation,the transformed quantum state still maintains the form of the original quantum state,and its relative parameters remain unchanged when the speed approaches the speed of light.
