quantSim: A Classical Quantum Circuit Simulator with Examples

• Based off the Qiskit API but does not use Qiskit or any other quantum related libraries
• system_design_doc.md: Program usage, architecture, class descriptions, details on error checking
• design_doc.md: Requirements and testcases
• info.md: Usage, list of available gates, miscellaneous project info

Features

• Supports basic quantum gates similar to Qiskit
  • Supports most gates listed from this Wikipedia page
• Supports custom qubit ordering for many-bit gates
  • Ex. Toffoli gate with control qubits Q4, Q1 and target qubit Q2
• Printing features:
  • Circuit diagram
  • Current statevector or probability distribution
  • Can inspect (print) between gate additions
• Doesn't support:
  • Measurements
  • Classical bits

Demos

• Bell State
• Grover's Search Algorithm
