A quantum deterministic key distribution(QDKD) protocol was proposed by using W states as a carrier which is suitable for quantum channel transmission. Under the precondition of photon stability, using quantum correlations and a public string S as a key to key distribution, a high efficiency of 54.54% was reached just almost with GHZ states, and photons were transmitted with a stronger robustness. Security analysis results show that this protocol could resist two common attacks, ensure the communication safe and reliable. Meanwhile, this protocol doesn’t involve any unitary operation. It’s easy handling.
