Indian researchers and engineers have successfully established a free-space quantum key distribution link spanning 5.56 km, ...

This process is fundamental to quantum key distribution," Ding said. "Some years ago, we only dreamt of using quantum dots in real-world quantum communication scenarios. Today, we are thrilled to ...

As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured ...

Researchers have successfully demonstrated India’s first 5.56 km free-space quantum key distribution link in Ahmedabad, ...

The ability to send quantum information securely, known as quantum key distribution, is one of the most practical (if difficult) applications of quantum science. A new study demonstrates the ...

India has successfully tested a 5.56-km open-air quantum key distribution link between BISAG-N and IIT Gandhinagar. The trial supports ISRO's plans for secure satellite-based quantum communication ...

Quantum technologies have long been limited by an awkward mismatch: the wavelengths where quantum light sources work best are ...

In the race to secure digital infrastructure against the looming threat of quantum computing, space has emerged as an indispensable theater. Satellites, once primarily vehicles for reconnaissance and ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, tackling one of the most persistent obstacles in quantum optics. The method ...
