Objective
A grand challenge of our age is to develop platforms for quantum information processing. The optical photon plays a key role: it allows quantum information to be transmitted over long distances and the encoded quantum information is robust, making photons attractive qubits for quantum computing. Resource states consisting of a small number of entangled photons constitute the fundamental building block that subsequently can be fused into larger entangled states by interference – a simple operation in photonics. These states can be tailored to be robust against errors and constitute a universal resource enabling full-scale quantum computing. We propose to create high-fidelity resource states with semiconductor quantum emitters for advanced quantum information processing applications realized on novel quantum hardware. Such an endeavor requires a very close collaboration between quantum materials science, semiconductor and device physics, quantum optics experiments, and quantum information theory/architecture development. We will develop low-noise quantum dots and fabricate waveguides and cavities to realize coherent spin-photon interfaces capable of generating highly indistinguishable multi-photon entangled states on demand. The operation wavelength will initially be in the near infrared and subsequently at the telecom wavelength. Using coherent spin control, we will generate seed entangled states with up to 10 photons, and photon fusion and dipole-coupled emitters will be employed to realize photonic quantum gates. Hereby advanced sources of multi-photon graph states with tailored entanglement topology can be obtained. Proof-of-principle demonstrations of device-independent quantum key distribution, quantum error correction, multimode quantum networks, and elementary quantum computation protocols will be realized. In a close interaction with theory, a reliable scaling-up roadmap will be developed towards real-world applications in quantum computing.
