- Abstract: Secure quantum communication protocols based on a prepare-and-measure scheme
employ mutually unbiased bases. In these protocols, many runs, in which
different participants measure in different bases, simply go wasted. In this
paper, we show that it is possible to reduce the number of such runs by a
suitable design of the key generation rule. This results in a significant
increase in the key generation rate (KGR). We illustrate this advantage by
proposing quantum and semi-quantum key distribution protocols by employing
effective qubits encoded in higher dimensional quantum systems. None of them
demands the preparation of entangled states as resources and a relatively large
amount of information can be transferred. For this reason, we believe that our
proposals are worth pursuing experimentally.

A proof of quantumness is an efficiently verifiable interactive test that an efficient quantum computer can pass.
Existing single-round protocols require large quantum circuits, whereas multi-round ones use smaller circuits but require experimentally challenging mid-circuit measurements.
We construct efficient single-round proofs of quantumness based on existing knowledge assumptions.
