Program Plan Intro

Systems development life cycle (SDLC) phases:

  • The seven phases in SDLC includes:
    • Planning phase:
      • The planning phase includes creating a goal statement for project.
      • It defines a high level plan for intended project.
      • It sets scope of project.
      • The project plan denotes a formal, approved document that would manage and control entire project.
      • A project manager creates a project plan and ensures that project finishes within given deadline and budget.
    • Analysis Phase:
      • In analysis phase the firm would analyze business requirements.
      • It refines goals of project into defined operations and functions of intended systems.
      • The business requirements denote specific business requests made by system so as to successfully complete project.
      • The requirements management denotes process of managing changes to requirements in business.
      • A requirements definition document would prioritize all business requirements based on importance order.
    • Design phase:
      • The design phase creates description for system features and operations.
      • It includes following items:
        • Screen layout
        • Business rules
        • Process diagrams
        • Pseudo code
      • The graphical user interface (GUI) denotes an information system interface.
    • Development phase:
      • The development phase transforms detailed design documents into actual system.
      • During this phase, the team defines programming language for development.
      • A scripting language may provide interactive modules to website.
      • Object oriented languages may group data into objects.
    • Testing phase:
      • The testing phase keeps all project modules under testing environment for elimination of bugs and errors.
      • It verifies that system meets all requirements mentioned in analysis phase.
      • Bugs denote defects in information system code.
      • The test conditions denote steps that should be performed and expected result for each step.
    • Implementation phase:
      • The system is placed into production, detailed documentation is performed.
      • The users begin actual operations in business within system.
    • Maintenance phase:
      • The organization performs corrections, changes and up gradations to ensure that system meets requirements.
      • Corrective maintenance would make system changes to flaws in design, errors in coding or issues in implementation.
      • Preventive maintenance would make system changes to reduce chances for system failure in future.

I need help to solve a simple problem using Grover’s algorithm, where the solution is not necessarily known beforehand. The problem is a 2×2 binary sudoku with two rules: • No column may contain the same value twice. • No row may contain the same value twice.   Each square in the sudoku is assigned to a variable as follows:   We want to design a quantum circuit that outputs a valid solution to this sudoku. While using Grover’s algorithm for this task is not necessarily practical, the goal is to demonstrate how classical decision problems can be converted into oracles for Grover’s algorithm.   Turning the Problem into a Circuit   To solve this, an oracle needs to be created that helps identify valid solutions. The first step is to construct a classical function within a quantum circuit that checks whether a given state satisfies the sudoku rules.   Since we need to check both columns and rows, there are four conditions to verify: v0 ≠ v1   # Check top row   v2 ≠ v3   # Check bottom row…
