Project Description


Project description:

Background: This project centers on modeling superconducting quantum processors. These processors consist of qubits (quantum bits) that exhibit intricate dynamics individually and through their interactions. A key challenge in accurately simulating such systems lies in accounting for their coupling to the surrounding environment, which may include other quantum systems, sources of decoherence, and loss mechanisms that are often difficult to isolate or control experimentally.


Tasks: We will use Python to integrate theoretical models and experimental data to build a realistic and reliable simulation framework. The main functions include:
· Modeling the dynamics of individual qubits and their interactions.
· Incorporating environmental effects, such as noise, loss, and crosstalk.
· Validating the simulation results against observed quantum behavior from laboratory experiments.
This approach ensures that the simulations reflect physical reality as closely as possible and can be used to guide future experimental designs.


Outcome: The goal is to develop a small-scale, comprehensive simulation of a superconducting quantum processor. The final model will include up to five qubits, capturing their mutual interactions and environmental influences. This simulation will serve as a foundational tool for:
· Understanding system-level quantum behavior.
· Exploring error mitigation strategies.
· Supporting the design and optimization of future quantum experiments.

Working hours per week planned:
