Although previous studies have found that the "group velocity" of light can travel faster than c, the "signal velocity" -the speed at which information travels -cannot.───尽管先前的研究已经证实,光的“群速度”可以超越光速c,而“信号传播速度”——光携带的信息的传播速度——不能超越光速。
The scientists found that the precursor wave front of a single photon always travels at c, like the signal velocity of large groups of photons.───科学家发现,单个光子的前驱波头一般以光速c传播,就像由大量光子携带的信号的传播速度一样。
In light of this finding, scientists have wondered whether single photons travel at the group velocity or the signal velocity.───在这些发现的基础上,科学家曾经怀疑,是否单个光子可以达到“群速度”和“信号传播速度”。
In light of this finding, scientists have wondered whether single photons travel at the group velocity or the signal velocity.
