From the return of the “Quantum Leap” TV show to the Nobel Prize, 2022 seemed to be the year when “quantum” reached a whole new level in the popular consciousness. In November, EPB and Qubitekk joined that conversation on a more business-minded level with the launch of America’s first industry-led, commercially available quantum network designed for private companies and other technologists to run quantum equipment and applications in an established fiber optic environment with the goal of accelerating the commercialization of quantum technologies. So, what are quantum technologies and why do they matter for your company and ultimately your customers?

Quantum-based communications reproduce a naturally occurring phenomenon in which light particles (photons) can be linked or “entangled” such that any change in one of the photons is instantaneously mirrored by its “twin” even when they are separated by great distances. In contrast to conventional computing and networking, which rely on sequential processing, entangled photons called qubits can be used to process multiple parallel paths of data at the same time. And these are just some of the ways quantum technologies hold the promise of breaking through current physical limits on existing computing, networking and sensing technologies.

The power of quantum technologies

Although the full realization of these possibilities will take decades, the development of quantum technologies continues to draw global interest and billions of dollars of investments because we have begun to make real strides in moving toward practical applications that represent groundbreaking possibilities to advance cybersecurity, sensing and next-generation computing. This holds the promise for revolutionary benefits in protecting people from cyberthreats, launching a next-generation Internet and developing new advancements in healthcare, finance and other industries.

For example, quantum technologies open the door to experiencing augmented reality and the future metaverse in ways that exceed even today’s science fiction films. Just think: instead of showing your children your wedding album, they can experience the festivities as you did.

Quantum isn’t just a faster version of the Internet. It holds endless possibilities. Imagine modeling new vaccines and medical treatments with the power of quantum computing. Or using artificial intelligence and advanced predictive modeling to enhance your company’s competitiveness. Quantum could create more interactive educational opportunities through photo-realistic virtual reality. The speed of the technology could make instantaneous multilanguage translations systems possible. Warnings could be issued before tornadoes, earthquakes, tsunamis and other natural disasters happen. Even gravitational waves could be used to explore the universe. We’re only beginning to appreciate the endless possibilities quantum can open.

In this context, protecting proprietary and personal information becomes even more important. Fortunately, through the entangled nature of paired photons, quantum key distribution offers a completely new approach to cybersecurity and threat prevention that eclipses even our best measures today.

And yet, the US is in danger of falling behind other global players in the development of quantum technologies, and this places an even greater urgency on the national priority to make more rapid progress.

One of the current challenges for private companies aiming to innovate in the emerging quantum industry is that foundational quantum networking equipment is expensive and primarily located in government and academic lab environments. As we’ve seen since the launch of the Internet, some of the biggest gamechangers came from independent entrepreneurs pursuing solutions to some of our most common daily issues. That spirit of innovation and enterprise has been essential to the launch of some of our country’s most successful and most recognizable companies. That’s what drove us to launch EPB Quantum Network powered by Qubitekk.

Sharing quantum states

If you’re familiar with EPB, you know we’re a municipal electric and fiber optic utility located in Chattanooga, Tennessee. Given that context, the launch of this new quantum network may seem strange, but this project actually builds on more than a decade of effort.

In 2008, EPB began to deploy a community-wide fiber optic network which would serve as the communications backbone of Chattanooga’s Smart Grid, a next-generation electric system to reduce outages, improve response time, reduce theft and help customers manage their electric power usage. With the onset of the Great Recession later that year, the Department of Energy supplemented EPB’s initial investment with a $111 federal stimulus grant, allowing EPB to accelerate its 10-year plan for building out the fiber-optic-based Smart Grid such that it became accessible to every home and business in our 600-square mile service area in just two years.
