Teleporting Quantum-Dot Spin States

Large-scale arrays of electron spins in gate-defined quantum dots have emerged as key elements of spin-based quantum information processors. Electron spin qubits naturally interact with each other via nearest-neighbor exchange coupling. However, a central requirement for fault-tolerant quantum computing in linear arrays is the ability to transmit quantum states over long distances. In this talk, we discuss the experimental realization of a quantum teleportation protocol for electron spins in semiconductor quantum dots. We present evidence consistent with conditional teleportation of spin eigenstates, entangled states, and gate teleportation, and we discuss interesting possible future directions.
