Dr Jennewein s proposal is for Alice to beam polarisation-encoded photons to a satellite.
詹内怀恩博士的计划建立在以艾莉斯为基础上的,她计划发送偏振编码的光子给卫星。
Once she has established a key, Bob, on another continent, will wait until the satellitepasses over him so he can send some more photons to it to create a second key.
一旦她建立起一个密钥,那么当卫星运行到位于另一个大陆的鲍伯附近时,鲍伯就可以发送更多的光子给它,就建立起了第二个密钥。
The satellite will then mix the keys together and transmit the result to Bob, who can workout the first key because he has the second.
卫星届时会把这两个密钥混合起来,再把结果传输给鲍伯,拥有第二个密钥的鲍伯就可以解开第一个密钥。
Alice and Bob now possess a shared key, so they can communicate securely by normalterrestrial networks.
艾莉斯和鲍伯则会拥有一个共享密钥,所以他们能够通过正常的地面网络进行安全地联系。
Dr Jennewein plans to test the idea, using an aircraft rather than a satellite, at some pointduring the next 12 months.
詹内怀恩博士计划在未来一年内的某个时候,用飞机,而不是卫星测试一下这个想法。
