As he waited to begin training with the U.S. Space Force in Colorado Springs, Jacob Sotel-Jackson realized his path into one of the nation鈥檚 newest military branches began with a single, unlikely decision: enrolling in a quantum computing elective at the 最新天美传媒. He didn鈥檛 know at the time, but choosing that elective course would be life changing.
鈥淚 had no idea what quantum computing was, at the time鈥� he said. 鈥淚t sounded kind of out there.鈥�
At the urging of a friend with the same major, they discussed taking a class together, and Associate Professor Richard Rauscher鈥檚 class in quantum computing was open.
Looking at the requirements, he knew linear algebra was part of the curriculum, and he wasn鈥檛 looking forward to working on that kind of math. This was an elective.
鈥淭hat wasn鈥檛 something I was interested in,鈥� he remembers. 鈥淏ut my friend convinced me to just jump into this and take the class with him.鈥�
Now, he鈥檚 a second lieutenant enjoying some down time in Colorado Springs before reporting to his initial training with the U.S. Space Force 鈥� and quantum computing is part of his daily life.
鈥淚 don't if I would have really gone and done a deep dive into quantum without that class,鈥� he said. 鈥淭he more I learned about it, I was super fascinated by it. It just sparked a real big interest in me. I saw that this is something that could really change the world in the next couple decades.鈥�
From USF ROTC to the U.S. Space Force
USF was a natural choice for college. His mother was a nursing school graduate, it was right down the road from his home, and as a child, he spent time on campus attending STEM activities that the university hosted.
鈥淭hat got me interested,鈥� he said. 鈥淚 had also always been interested in computers and video games from a young age.鈥�
Similarly, military service was a natural choice for him. Both of his parents were U.S. Army veterans who recommended he join USF鈥檚 ROTC program. The U.S. Space Force was still so new, it wasn鈥檛 represented in the ROTC program then. But the U.S. Air Force was, and part of the Air Force mission statement at that time included protecting cyberspace.
鈥淭hat just aligned with what I was really interested in,鈥� he said. 鈥淲hen then the opportunity for me to go into Space Force popped up, I thought, 鈥極h, this is pretty cool.鈥欌��
How a quantum computing class changed a career direction
Sotel-Jackson was content taking the core computer science classes.
鈥淚t was very grounded in traditional computing, zero, ones 鈥� binary bits 鈥� and regular programming,鈥� he said.
Then his friend convinced him to enroll in that quantum elective.
Quantum computing is relatively new as a practical technology, but the science behind it is decades old. It uses the rules of quantum physics to solve certain problems much faster than today鈥檚 computers. Instead of processing information as simple on-or-off bits, quantum computers use quantum bits that can represent many possibilities at once, allowing them to tackle extremely complex calculations.
鈥淚t was a difficult class,鈥� he said. 鈥淚t was like nothing I had done in computer science before. It was completely different because at its core, it鈥檚 quantum mechanics rather than computing in binary zeros and ones that we鈥檙e used to in regular computer science."
His curiosity didn鈥檛 end when the course was over. In his free time, he read textbooks to learn more. Then he took another graduate-level course on quantum information before his graduation.
鈥淭he opportunity came up to for me to get a graduate degree through the Space Force, just after commissioning,鈥� he said. 鈥淲hen I was looking into different programs, I decided that what I wanted to do was actually research quantum computing. That's what guided my graduate degree search.鈥�
Sotel-Jackson graduated from 最新天美传媒 in 2024 and earned a master鈥檚 degree from Purdue University 18 months later.
Through his graduate research, Sotel-Jackson focused on the use of hybrid quantum-classical machine learning for the security analysis of quantum key distribution channels for sharing encryption keys.
While he doesn鈥檛 yet know the details of what he will be doing with Space Force, he knows he has the latest knowledge to tackle whatever project comes his way.
He recently reached out to his former faculty member via email, thanking him for the class that inspired this passion.
鈥淥ver the semester, I realized it was one of the most intriguing and fascinating topics I had ever encountered,鈥� he wrote. 鈥淚 decided that I want to be part of this. I want to make sure that I'm near the front of this and I'm prepared and knowledgeable. When this stuff does become mainstream, and it does have a significant impact on the world, I want to be able to look back and say that it basically all started with that class."
