一个未知的量子态[φ]可以被分解为纯经典信息和纯非经典的爱因斯坦-波多尔斯基-罗森（EPR）关联，然后由它们重构。要做到这一点，发送者“爱丽丝”和接收者“鲍勃”必须预先安排EPR相关粒子对的共享。Alice对她的EPR粒子和未知量子系统进行联合测量，并将测量的经典结果发送给Bob。知道了这一点，鲍勃就可以把他的EPR粒子的状态转换成爱丽丝摧毁的未知状态\phi]）的精确复制品。
An unknown quantum state \phi] can be disassembled into, then later reconstructed from, purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations. To do so the sender, ''Alice,'' and the receiver, ''Bob,'' must prearrange the sharing of an EPR-correlated pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the state of his EPR particle into an exact replica of the unknown state \phi]) which Alice destroyed.
