Quantum information science (QIS) has been blossoming in the past twelve years and as the possibility of a quantum computer sparks more interest in the field, the need to have a better understanding of fundamental questions arises. Specifically, questions concerning the resources needed for quantum information tasks, such as quantum teleportation, are of the utmost importance. The key resource for some of these QIS tasks is entanglement: a quantum mechanical phenomenon in which observable physical properties of two or more spatially separated systems are correlated in a manner that has no classical analog. Entanglement demonstrates that QIS contains essentially new types of resources that differ vastly from the sort of resources encountered in classical information theory.

量子信息科学（QIS）在过去的12年里蓬勃发展，随着量子计算机的可能性激发了人们对该领域的更多兴趣，人们需要更好地理解基本问题。具体来说，关于量子信息任务（如量子隐形传态）所需资源的问题至关重要。其中一些QIS任务的关键资源是纠缠：一种量子力学现象，其中两个或多个空间分离系统的可观察物理特性以一种没有经典模拟的方式相关。纠缠表明，QIS包含本质上是新类型的资源，这些资源与经典信息论中遇到的资源种类有很大不同。
