Quantum networks, systems consisting of connected quantum computers, quantum sensors or other quantum devices, hold the potential of enabling faster and safer communications. The establishment of ...

A team of researchers from University of Toronto Engineering has discovered hidden multi-dimensional side channels in existing quantum communication protocols. The new side channels arise in quantum ...

If the Pentagon is to harness the promise of quantum-powered devices, it needs ways to connect them to today's data networks. But networking has been the “black sheep” of quantum research, says the ...

For more than two decades, the quantum communications market has largely centered on quantum key distribution (QKD): the exchange of encryption keys protected by the laws of quantum physics. But a ...

Researchers at the Niels Bohr Institute have broken a long standing barrier by managing to send single photons - that can’t be copied or split and thus are secure - in the network of optical fibers we ...

Researchers at Rochester Institute of Technology and University of Rochester recently connected their campuses with an experimental quantum communications network using two optical fibers. In a new ...

Scientists have taken a major step toward ultra-secure quantum communication by demonstrating a remarkably stable quantum encryption system that worked across more than 120 kilometers of optical fiber ...

For more than 40 years, we have been building the modern internet on foundations that were never designed for the world we live in today. When the architects of the early internet created its ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...
