Comment on 'Semi-Quantum Private Comparison Based on Bell States'
You-Lin Chen, Yu-Chin Lu, Zhong-Xuan Lin +1
This study points out a semi-quantum protocol for private comparison using Bell states (SQPC) suffering from the double C-NOT attack and the malicious agent attack. The attacker ca…
Measure-resend authenticated semi-quantum key distribution with single photons
Chun-Hao Chang, Yu-Chin Lu, Tzonelih Hwang
Yu et al. and Li et al. have proposed the measure-resend protocols of authenticated semi-quantum key distribution (ASQKD). A new measure-resend ASQKD protocol is proposed in this p…
Quantum Key Recycling can share key more efficient than BB84
Yu-Chin Lu, Chia-Wei Tsai, Tzonelih Hwang
We calculate the key sharing rate of Lu et al.'s Quantum Key Recycling (QKR) protocol. The key sharing rate is another version of the key rate, but it can be calculated for both th…
Quantum Key Recycling with Optimal Key Recycling Rate based on Error Rate
Yu-Chin Lu, Chia-Wei Tsai, Tzonelih Hwang
We propose a new Quantum Key Recycling (QKR) protocol, which can tolerate the noise in the quantum channel. Our QKR protocol recycles the used keys according to the error rate. The…
