GothamQ platform - 34km of wires and data protection at the speed of light.
Last December, a unique quantum experiment unfolded under the streets of New York. For 15 days, photons of light traveled through an underground network stretching from the Brooklyn Navy Yard to the Crown district of Queens. The 34-kilometer-long quantum network is Qunnect's test platform called GothamQ.
The researchers used the city's existing fiber-optic infrastructure, but instead of ordinary photons, they transmitted entangled polarized particles of light. The photons were in a quantum state, which made the experiment truly revolutionary.
Mehdi Namazi, chief scientist at Qunnect, compared the significance of their work to the invention of the internet. According to him, it is difficult to predict all possible applications of the technology, but its potential is huge. The team generated pairs of photons using a rubidium-87 vapor cell. These pairs had interdependent properties and were used as qubits, particles of information that underpin quantum computing.
An impressive achievement was the speed of transmission: half a million pairs of photons per second passed through the system. Over the entire period of the experiment, 648 billion pairs of photons were transmitted. This is many times higher than the results of previous similar experiments, where the speed reached only 10-20 thousand pairs per second.
The peculiarity of photons lies in their ability to carry quantum information at room temperature. Thanks to this, the researchers were able to use ordinary urban infrastructure, rather than a specially equipped laboratory. The network worked with impressive stability — 99.84% of the time of the experiment. Moreover, its completion was not due to technical problems, but only to the need to move on to the next tasks of the project.
An innovative solution was the use of short pauses in the operation of the quantum network. In millisecond intervals, pulses of classical light were passed through the system. They served as a kind of markers that made it possible to assess the condition of the equipment and identify possible interference.
The scientists sought to create a reliable and stable system for distributing quantum entanglement that could find application in the real world. The immediate prospects for the use of technology lie in the field of cybersecurity. Quantum data transmission promises to become almost invulnerable to hacker attacks, since any interference with the system is detected instantly. However, widespread practical application is still a long way off. Namazi compared the current data transfer speed to dial-up internet, noting that it is 10 times faster, but still far from modern standards.
