An impediment to scaling up these approaches, however, was that the quality of the entangled state decreased as the number of ions increased.
然而，当离子数量增加，缠结状态的品质就会下降，这种特性便成了这项技术的一道障碍。
Quantum bits, or qubits, can also be entangled - the state of one qubit influences the state of another even at a considerable distance.
量子位，或称量位，也会互扰- - -即便相离甚远，某个量位的状态还是会影响另一个量位的状态。
The other two, B and c, are created further down the line in an entangled state, and sent off in different directions.
另外两个分别是B和C，它们在另外一点以纠缠态被生成，并被以不同方向传送。
