We are all alumni of QxQ Intro To Quantum Computing Course. The course taught us about quantum mechanics, quantum computing, and much more. Owing to the insights and inspiration we got from the course, we were able to continue working on this amazing field. Then, when we joined this hackathon, we found out about a paper called “A Quantum Algorithm For High Energy Physics Simulations” and got very interested in it. So, why not give it a try?
What it does
The paper we implemented was about a quantum algorithm which worked with a Markov Chain Monte Carlo method, and explained how a high energy simulation could be created using a quantum algorithm with a given example of a Parton shower model’s simulation, and how it could be modeled using a quantum algorithm which is then looped to create the expected results, possibilities and required materials. Our project aims to make use of this paper, and consequently create a simplified version of the proposed circuit.

How we built it
We built it using Python and Qiskit. We replaced the unitary gates in the paper with controlled not gates, since doing this provided us a good starting point to improve our circuit more and more in the future.
Challenges we ran into
Quantum field theory is a hard topic to understand. Certainly, understanding it in 24 hours is harder. Also, the proposed circuit from the paper was a highly generalized circuit, which meant we had to find our own original ways of composing such a circuit. For that, we had to examine a couple of types of circuits.
Accomplishments that we're proud of
As three high school students from different backgrounds, we read and evaluated a master's degree article in a limited time and designed a project on this subject. This helped us learn about how the universe works on a particle-level, the terminology required to understand these topics and practices of Quantum Computing that we didn't know about .
What we learned
First of all, we learned Quantum Field Theory, Standard Model explanation, MCMC and many more… We also got to practice our coding skills.
We are highly interested and enthusiastic about making our experiment idea real and this hackathon is our first step for that achievement. In the future, the circuit can be improved by adding momentum fractions and azimuthal angles as parameters. Also, we can represent bosons such as W and Z to improve the dark matter research, by using a larger circuit. But, we're leaving that to the professionals, you know, for now.
