What are the Applications of SPDC in Nanotechnology?
1. Quantum Communication: SPDC is employed to generate entangled photon pairs, which are key for secure quantum communication protocols like Quantum Key Distribution (QKD). 2. Quantum Computing: The photon pairs can be used as qubits in various quantum computing schemes. 3. Metrology: SPDC offers highly sensitive measurement techniques, aiding in the development of highly accurate quantum sensors. 4. Imaging: Techniques like ghost imaging leverage SPDC for high-resolution imaging beyond the diffraction limit.
