The leadership of Manassas, Virginia-based SylLab Systems doesn’t want you to think about quantum as a far-off, hard-to-understand technology. It instead wants other company heads to think about how the tech will impact their security systems when it arrives.

Founder and CEO Bart Slowik created SylLab Systems, which is based on post-quantum cryptography — more on that below — to push peers into considering that exact future. Slowik started the post-quantum security startup, his second company, in late 2019 because he and his four-person team are “essentially privacy and cryptography enthusiasts” who recognized the challenge ahead once quantum systems reached their full potential. He expects that development within the decade, with computers still relying on existing security that’s not designed to defend against quantum threats. He thus created SylLab to secure the internet of today against future quantum threats by helping companies transition their cyberinfrastructure to a post-quantum world.

Post-quantum cryptography differs from cybersecurity through quantum key distribution; Quantum key requires quantum computers, which are still being fully built out. Quantum cryptography, on the other hand, is about securing the computers of today against future quantum attacks with algorithms.

“Cryptography is like a utility,” Slowik told “So, basically, security is in anything that we do: Anything you write and say digitally is secured by cryptography in some sense. So that being threatened by quantum computers — it’s an enormous task in front of us.”

So far, SylLab has partnered with George Mason University and the University of Maryland’s Quantum Startup Foundry. It also received investments from Virginia Innovation Partnership Corporation, Prince William County, VentureScope, and Marl5G; was an Ignite Grant winner and took third place in the pitch competition held at the Quantum World Congress.

SylLab primarily works with large enterprises, Slowik said, because they have the most critical need. Within that, he sees defense and healthcare as the industries with the most urgent concerns, both in the private and public sectors.

“We care a lot about privacy and security,” Slowik said. “I believe that it’s is very important for us to have that security and privacy of the personal information that we share online.”

As the company grows, he’ll also be looking to expand into the financial industry. He additionally aims to have full implementation of the technology with clients in existing infrastructure. In the near term, he anticipates opening a funding round, likely sometime next year.

But for Slowik, post-quantum cryptography doesn’t stop with what his company is doing now. He sees many future applications in the supply chain, healthcare, the internet of things and more.

It’s not only about post-quantum cryptography because it raises the security levels, but it’s also solving the problems of today,” Slowik said.
