Pull Request Overview

This PR adds a requirements.txt file to specify dependencies for a quantum error mitigation (QEM) on hardware project. The title suggests this is related to expectation maximization (EM) and compilation functionality.

• Adds comprehensive quantum computing dependencies including Cirq, Qiskit ecosystem packages, and Mitiq
• Includes data science libraries (NumPy, Pandas, Matplotlib) for analysis and visualization
• Adds parsing library (PLY) likely for compilation features

potential next steps from brainstorming with @bachase:

1. compare existing plots to a structured circuit
2. given a fixed budget (e.g. # of gates), what mix of QEM/compilation work best? How much ZNE-budget increase do you get from compiling?
3. compiling to a QPU usually means increasing resources, how does that impact results?
