Experimental realization of quantum teleportation using coined quantum
  walks
The goal of teleportation is to transfer the state of one particle to another
particle. In coined quantum walks, conditional shift operators can introduce
entanglement between position space and coin space. This entanglement resource
can be used as a quantum channel for teleportation, as proposed by Wang, Shang
and Xue [Quantum Inf. Process. 16, 221 (2017)]. Here, we demonstrate the
implementation of quantum teleportation using quantum walks on a five-qubit
quantum computer and a 32-qubit simulator provided by IBM quantum experience
beta platform. We show the teleportation of single-qubit, two-qubit and
three-qubit quantum states with circuit implementation on the quantum devices.
The teleportation of Bell, W and GHZ states has also been demonstrated as
special cases of the above states.
