Query: Keyless Semi-Quantum Point-to-point Communication Protocol with Low
  Resource Requirements   Full quantum capability devices can provide secure communications, but they
are challenging to make portable given the current technology. Besides,
classical portable devices are unable to construct communication channels
resistant to quantum computers. Hence, communication security on portable
devices cannot be guaranteed. Semi-Quantum Communication (SQC) attempts to
break the quandary by lowering the receiver's required quantum capability so
that secure communications can be implemented on a portable device. However,
all SQC protocols have low qubit efficiency and complex hardware
implementations. The protocols involving quantum entanglement require linear
Entanglement Preservation Time (EPT) and linear quregister size. In this paper,
we propose two new keyless SQC protocols that address the aforementioned
weaknesses. They are named Economic Keyless Semi-Quantum Point-to-point
Communication (EKSQPC) and Rate Estimation EKSQPC (REKSQPC). They achieve
theoretically constant minimal EPT and quregister size, regardless of message
length. We show that the new protocols, with low overhead, can detect Measure
and Replay Attacks (MRAs). REKSQDC is tolerant to transmission impairments and
environmental perturbations. The protocols are based on a new quantum message
transmission operation termed Tele-Fetch. Like QKD, their strength depends on
physical principles rather than mathematical complexity.
