Lightweight Mediated Semi-Quantum Secret Sharing Protocol

Chia-Wei Tsai, Zong-Liang Zhang, Bo-Cheng Jian +1

Due to the exiting semi-quantum secret sharing protocol have two challenges including (1) the dealer must be the quantum user, and (2) the classical users must equip with the Troja…

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…
