Realization of Deterministic Quantum Teleportation with Solid State Qubits

Understand

Transferring the state of an information carrier from a sender to a receiver is an essential primitive in both classical and quantum communication and information processing.

• In a quantum process known as teleportation the unknown state of a quantum bit can be relayed to a distant party using shared entanglement and classical information.
• Here we present experiments in a solid-state system based on superconducting quantum circuits demonstrating the teleportation of the state of a qubit at the macroscopic scale.
• In our experiments teleportation is realized deterministically with high efficiency and achieves a high rate of transferred qubit states.
