Quantum teleportation allows protected information exchange between distant parties, a crucial resource in future quantum networks. Using high-dimensional quantum states for teleportation offers the promise of higher information capacity channels, protection against optimal cloning machines and improved resilience to noise. However, such promising advantages are limited by the commonly used linear optical detection schemes that require ancillary photons, where the number of entangled photons grows with the dimension of the quantum state to be teleported. Here we overcome this restriction and experimentally realise the teleportation of high-dimensional states with just three photons, enabled by nonlinear optical detection. To create high-dimensional quantum states we employ photonic spatial modes and demonstrate a ten-dimensional teleportation channel, exceeding the state-of-the-art of two spatial modes for qubit teleportation and qutrit teleportation with four and five photons. Our experimental scheme is not basis dependent and easily scaled in dimension without changing its three-photon configuration, making high-dimensional teleportation practically feasible for future high-bandwidth robust quantum networks.Quantum teleportation allows protected information exchange between distant parties, a crucial resource in future quantum networks.

Quantum teleportation scheme by selecting one of multiple output ports

Satoshi Ishizaka, Tohya Hiroshima

The scheme of quantum teleportation, where Bob has multiple $(N)$ output ports and obtains the teleported state by simply selecting one of the $N$ ports, is thoroughly studied. We consider both the deterministic version and probabilistic version of the teleportation scheme aiming to teleport an unknown state of a qubit. Moreover, we consider two cases for each version: (i) the state employed for the teleportation is fixed to a maximally entangled state and (ii) the state is also optimized as well as Alice's measurement. We analytically determine the optimal protocols for all the four cases and show the corresponding optimal fidelity or optimal success probability. All these protocols can achieve the perfect teleportation in the asymptotic limit of $N\ensuremath{\rightarrow}\ensuremath{\infty}$. The entanglement properties of the teleportation scheme are also discussed.The scheme of quantum teleportation, where Bob has multiple $(N)$ output ports and obtains the teleported state by simply selecting one of the $N$ ports, is thoroughly studied.
