Abstract
Experimental one-way decoy pulse quantum key distribution running for 25 h over a fibre distance of 25 km is reported. The decoy pulse protocol employed uses two weak pulses (signal and decoy) and one vacuum pulse. In parallel to the key sifting, simultaneous error correction and privacy amplification yielding a final, average secure key rate of 5.7 kbps are performed. The random bits from the secure keys are found to pass stringent statistical tests.
