About Thrust 3
Quantum repeaters, as well as other special-purpose quantum computing devices like networking gateways, will require quantum memories, as well as spin-photon interfaces to interface qubits to the modern telecommunications infrastructure. Each of these subcomponents presents its own engineering challenges and requires collaboration across multiple disciplines.
