Quantum key distribution (QKD), a cryptographic technique rooted in quantum physics principles, has shown significant potential for enhancing the security of communications. This technique enables the ...

The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built ...

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...

Quantum Photonics Group of BAQIS, led by Chief Scientist Dr Zhiliang Yuan and in collaboration with the Institute of Semiconductors CAS, has recently published a research article entitled “A ...

Controlled generation of single-photon emitters in silicon (red) by broad-beam implantation of ions (blue) through a lithographically defined mask (left) and by a scanned focused ion beam (right).
