  A large number of quantum location verification protocols have been proposed.
All existing protocols in this field are based on symmetric cryptography where
verifiers and the prover use the same secret key. The prover obtains secret key
from different verifiers, in pieces through public channels, which may result
in security compromise. In this paper, we give a formulism to prove
information-theoretic position-based quantum cryptography is possible in
asymmetric quantum setting. We propose a quantum location verification protocol
based on asymmetric quantum cryptographic where two different keys will be
used.
