Single photons can quickly modify individual electrons embedded in a semiconductor chip and vice versa, an advance that could be a significant step toward establishing quantum networks in the future. Such networks would transmit qubits from place to place and would offer unbreakable security for the transmitted information. But researchers must first develop ways for qubits that are better at storing information to interact with photons that are better at transporting it, a task achieved in conventional networks by electro-optic modulators that use electronic signals to modulate properties of light.
