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 ...

Quantum-based systems promise faster computing and stronger encryption for computation and communication systems. These systems can be built on fiber networks involving interconnected nodes which ...

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).

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 ...

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 ...
