Amazon is opening a quantum network research center

Some big companies are working projects, including and . Amazon is also on this list. Company The AWS Center for Quantum Computing last year and has through Amazon Web Services since 2019. Scaling up the work in what it says is an essential aspect of helping quantum technology reach its full potential: quantum networks. Thus, the company has AWS Center for Quantum Networks (CQN).

As with quantum computing, these are the early days of quantum networks. It might be before researchers begin to make the most of quantum technology. However, Amazon has more resources than most to invest in this area.

Amazon notes that quantum networks will be able to connect quantum devices using single photons rather than laser beams (used in modern optical communications). However, along with enabling certain capabilities of the quantum lattice, there are several hurdles to overcome when using a single photon. Quantum mechanics limits the gain of a single photon, limiting the range of the lattice. CQN research scientists Denis Sukachev and Mihir Bhaskar write in a blog post: “In addition, the weakness of single photons further complicates their communication with quantum computing devices. now.

Researchers at the center will work on new technologies, such as quantum repeaters and probes, that will enable the creation of global quantum networks. They will develop hardware, software and applications for quantum networks.

Among the potential uses of quantum networks are “enabling global communications protected by quantum key distribution with a level of privacy and security not achievable by conventional encryption techniques”, Sukachev and Bhaskar write. “The quantum network will also provide powerful and secure cloud quantum servers by connecting with each other and amplifying the capabilities of individual quantum processors.”
