We experimentally demonstrate transporting continuous quantum variables of individual light pulses at telecommunication wavelengths by using continuous-variable Bell measurements and post-processing displacement techniques. Time-domain pulsed homodyne detectors are used in the Bell measurements and the quantum variables of input light are transported pulse-by-pulse. Fidelity of F = 0.57 ± 0.03 is experimentally achieved with the aid of entanglement, which is higher than the bound (Fc = 0.5) of the classical case in the absence of entanglement.
