• Abstract: Reference-Frame-Independent Quantum Key Distribution (RFI-QKD) provides a practical way to generate secret keys between two remote parties without sharing common reference frames. On the other hand, Measurement-Device-Independent QKD (MDI-QKD) offers high level of security as it immunes against all the quantum hacking attempts to the measurement devices. The combination of these two QKD protocols, i.e., RFI-MDI-QKD, is one of the most fascinating QKD protocols since it holds both advantages of practicality and security. For further practicality of RFI-MDI-QKD, it is beneficial to reduce the implementation complexity. Here, we have shown that RFI-MDI-QKD can be implemented using fewer quantum states than those of its original proposal. We found that, in principle, the number of quantum states for one of the parties can be reduced from six to three without compromising security. Comparing to the conventional RFI-MDI-QKD where both parties should transmit six quantum states, it significantly simplifies the implementation of the QKD protocol. We also verify the feasibility of the scheme with the proof-of-principle experiment.

• One-sided DI-QKD secure against coherent attacks over long distances [0.0]
  Device-Independent (DI) QKD protocols overcome this issue by making minimal device assumptions. We show that a one-sided DI QKD scheme with two measurements per party is secure against coherent attacks up to detection efficiencies greater than 50.1% specifically on the untrusted side. We also show that, by placing the source of states close to the untrusted side, our protocol is secure over distances comparable to standard QKD protocols.

We propose a single-photon-memory MDI QSDC protocol (SPMQC) for dispensing with high-performance quantum memory.
