论文摘要

如果我们使用路径积分方法,则可以以显着相对论的方式编写量子电动力学(QED)。但是,路径积分仅限于大壳上的路径。如果我们通过在能量动量空间中的所有路径上计算路径积分来扩展QED,而不仅仅是质量壳上的路径?我们使用协方差的要求以明确的方式进行。这给出了一个QED,其中时间/能量成分以明显平行于空间/动量组件的方式出现的方式:我们有时间分散,及时的纠缠,Heisenberg的全面等效性(HUP)的不确定性原理(HUP)在太空中的HUP及时与HUP等等。及时纠缠的副作用是消除紫外线差异。我们在长期限制中恢复了标准QED。我们可以预测Attoseconds尺度的影响。随着ATTOSOND物理学和量子计算方面的最新发展,应检测到这些影响。由于预测是明确的,可检验的方法是可伪造的。伪造会增强我们对时间在QED中的作用的理解。确认将对Attosond物理学,量子计算和通信以及量子坟墓产生重大影响

If we use the path integral approach, we can write quantum electrodynamics (QED) in a way that is manifestly relativistic. However the path integrals are confined to paths that are on mass-shell. What happens if we extend QED by computing the path integrals over all paths in energy momentum space, not only those on mass-shell? We use the requirement of covariance to do this in an unambiguous way. This gives a QED where the time/energy components appear in a way that is manifestly parallel to the space/momentum components: we have dispersion in time, entanglement in time, full equivalence of the Heisenberg uncertainty principle (HUP) in time to the HUP in space, and so on. Entanglement in time has the welcome side effect of eliminating the ultraviolet divergences. We recover standard QED in the long time limit. We predict effects at scales of attoseconds. With recent developments in attosecond physics and in quantum computing, these effects should be detectable. Since the predictions are unambiguous and testable the approach is falsifiable. Falsification would sharpen our understanding of the role of time in QED. Confirmation would have significant implications for attosecond physics, quantum computing and communications, and quantum grav
