Neutron Activation Analysis at Goethe University Frankfurt
Thomas Barbera, Konstantin Bauer, Joe Henning, Stephen Heritage, Rachel Johnson, Michelle Kwok
Over fall break, I travelled to Frankfurt, Germany to conduct nuclear astrophysics research at Goethe University. My group
used neutron activation analysis techniques to analyze the chemical composition of an American quarter, Zirconium earrings,
and a ring of unknown material that we determined was largely nickel. We also toured the GSI nuclear facility and explored
the city.

ELENCO Radio Kit
Rachel Johnson
For my Intro to Circuitry and Electronics class, I built an AM/FM radio reciever. I learned to solder and I learned how the
radio works. I also wrote a paper explaining the entire AM circuit from antenna to speaker.

Evaluating the Accuracy of Quantum Computers through a Quantum Fourier Transform Algorithm
Dorothy Gan, Rachel Johnson, McKenna Leichty
Abstract: This paper presents a method of evaluating the accuracy of current superconducting quantum computers. A Quantum
Fourier Transform algorithm was developed and run on multiple quantum computers as well as a simulation. The circuit was run on each machine
2048 times and the results were compared. The quantum computers resulted in an average of 75.20% measured in the |101⟩ state, indicating a 24.80%
error when compared to the simulation which had measured 100% in the |101⟩ state as expected. Future experimentation could examine the accuracy on
a wider array of quantum algorithms or compare different types of quantum computers such as trapped ions or quantum dots.

This system monitors the moisture of the soil of my plant and reminds me when to water. It prints the moisture to an LCD display
and lights a red LED when it is time to water. The sensitivity can be easily adjusted to accomodate for different types of plants
in order to avoid overwatering.

Calculating e Using Monte Carlo Methods and Quantum Amplitude Estimation
Aaron Lamoreaux,
Rachel Johnson,
James Rayman
Project Page
Abstract: Quantum amplitude estimation techniques may be used to compute the expected
value of a quantum Monte Carlo algorithm more accurately than the naive, classical method. In this project, we implement a
quantum Monte Carlo algorithm for e=2.71828... and apply quantum amplitude estimation. Submitted to iQuHACK Hackathon at MIT.

Amalie Emmy Noether and Noether's Theorem
Rachel Johnson
Abstract: This paper presents an introduction to the life of Amalie Emmy Noether (1882-1935) and Noether's Theorem.
The early life and education of Noether is examined as well as Noether's gradual acceptance into the mathematics community
as an outstanding woman in her field. Finally, Noether's Theorem on the relationship between symmetries and conservation
laws is discussed. Submitted as final project for Math 20180.

Calculating Planck's Constant Using LEDs
Alec Cannon,
Dorothy Gan,
Rachel Johnson
Abstract: This paper presents a method of measuring Planck’s constant using light emitting diodes (LEDs).
An LED was connected to a variable power source and the voltage was gradually increased until the LED emitted
light. From this threshold voltage, the voltage was steadily increased and both current and voltage were
measured. Repeating this process with 5 different wavelengths of light yielded a value for Planck’s constant of
8.12 x 10-34 m2 kg s-1. The percent error was calculated to be 22.5% when
compared to the known value of h, 6.626 x 10-34 m2 kg s-1. This error can be
attributed to internal heating of the wires and the model of LEDs as resistors that follow Ohm’s Law.
Submitted as final project for Mechanics.
