Direct observation of temporal coherence by weak projective measurements of photon arrival time
Holger F. Hofmann, Changliang Ren
We show that a weak projective measurement of photon arrival time can be realized by controllable two photon interferences with photons from short-time reference pulses at a polari…

Analysis of the time-energy entanglement of down-converted photon pairs by correlated single photon interference
Changliang Ren, Holger F. Hofmann
The time-energy entanglement of down-converted photon pairs is particularly difficult to characterize because direct measurements of photon arrival times are limited by the tempora…

Clock synchronization using maximal multipartite entanglement
Changliang Ren, Holger F. Hofmann
We propose a multi party quantum clock synchronization protocol that makes optimal use of the maximal multipartite entanglement of GHZ-type states. To realize the protocol, differe…
