As part of the Quantum Computing Bootcamp for Summer 2025, I completed the following miniprojects:

1. Quantum Sudoku Solver (https://github.com/Runqiuxu/Sudoku_Erdos_proj1)
I wrote oracles to detect different qubits in Sudoku problem and use Grover’s algorithm to mark valid Sudoku solutions and amplify their amplitudes。

2. Quantum state preparation (https://github.com/Runqiuxu/QEP_Erdos_proj2)
I implemented a quantum phase estimation circuit combined with Grover’s algorithm to amplify the probability of measuring a specific target eigenphase and analyzed the resulting measurement probabilities on both ancilla and system qubits.

3. Steane's Code with Pauli error Channel (https://github.com/Runqiuxu/Steane_paulierror_proj3)
I implemented and simulated the Steane quantum error-correcting code in Qiskit, including logical state encoding, Pauli noise, syndrome measurement, and evaluation of error correction success rates.
