How to Use This Calculator
- Select Algorithm Type (Grover's search, Shor's factoring, etc.) and enter Problem Size to compare quantum vs. classical complexity.
- Use the Error Correction section: set Error Rate and choose a code type (Surface code, Steane, etc.) to see Physical Qubits required per logical qubit.
- Enter Coherence Time (µs) and Number of Qubits for the hardware platform to estimate achievable circuit depth.
- Read the Grover speedup (O(√N) vs. O(N)) or Shor exponential advantage to contextualize the quantum speedup.
- Use the measurement probability chart to verify qubit state readout probabilities after applying gate sequences.
