Russian scientists make teleportation a 'two-way road' using the same quantum resource

In quantum world teleportation is not a science fiction. But can teleportation be realized in both directions simultaneously? Scientists from Russian Quantum Center revealed that the answer is "yes". Moreover Alice and Bob can teleport quantum states of their bits (qubits) to each other using the same quantum resource as in the standard quantum teleportation protocol: preliminary shared pair of maximally entangled qubits (also known as Bell state), wrote Aleksey Fedorov and colleagues in a paper
