I am a Research Scientist with a Ph.D. in Condensed Matter Physics, currently transitioning into the quantum computing industry. My expertise lies in modeling quantum and superconducting devices, quantum coherence, and topological materials. I have led several simulation-driven research projects that bridge theoretical physics with experimental challenges, from topological superconductors to quantum coherence in device environments.

Here on GitHub, I am building a portfolio of quantum computing projects using Qiskit and QuTiP, showcasing my hands-on work in:

• Quantum circuit modeling and state analysis
• Josephson Junctions and transmon qubits
• Trotter methods to simulate time evolution of quantum systems
• Decoherence simulation in superconducting qubits
• Gate fidelity and qubit reliability under noise
• Hardware-aware transpilation and layout visualization
• Qiskit simulation of noise model, open quantum system
• Density-matrix simulations of noisy quantum circuits
• Translating physical intuition into simulation-driven insight

I am passionate about turning theory into practical tools and code that help advance next-generation quantum hardware.

• Josephson Junction → Transmon Qubit End-to-end modeling and simulation: connect device design to qubit behavior; run canonical control experiments with realistic noise.

• Floquet SPT-MBL Simulation in a 6-Qubit Chain
  Simulates a periodically driven disordered spin 6-qubit chain hosting edge-localized π-modes protected by many-body localization.

• Trotter Simulation of Superconducting Qubits
  Digitally simulate 2- and 3-qubit superconducting systems using second-order Trotter-Suzuki decomposition.

• Decoherence Simulation using QuTiP
  Model open quantum systems and extract T₁ and T₂ times in the presence of noise.

• Quantum Teleportation with Qiskit
  Demonstrates ideal and noisy quantum teleportation protocols with fidelity analysis across various error models and backends.

• Hardware-Aware Circuit Mapping
  Simulate and visualize transpilation of quantum circuits onto real hardware (e.g., Sherbrooke, Toronto) and fake backends (e.g., Athens, Jakarta).

• Two-Level System (TLS) Noise Modeling Simulate how TLS-induced fluctuations affect superconducting qubit coherence using QuTiP. Compare TLS vs. Lindblad models for realistic noise simulation.

• Density-matrix simulations of noisy quantum circuits: An intuition-first, reproducible sandbox that uses Qiskit Aer’s density-matrix simulator o build and probe noisy quantum circuits (Bell state) under depolarizing and T1/T2 relaxation, quantifying the impact via purity, Bloch vectors, and fidelity.

• Gate Fidelity under Realistic Noise (planned)
  Analyze quantum gate performance in the presence of measurement and decoherence noise.

I am also developing a habit of publishing my work openly and contributing to accessible, educational quantum computing content.
