  7. Number of qubits in Shor's algorithm circuit?

    Mar 4, 2025 · A very popular way to implement this circuit actually uses $2n + 3$ qubits, as described in S. Beauregard, Circuit for Shor’s algorithm using 2n+3 qubits. But if you are …

  8. How exactly does modular exponentiation in Shor's algorithm work?

    Feb 9, 2019 · Shor's paper was rightfully light on details on how modular exponentiation would be implemented, but his argument was effectively "because there's a classically fast solution to …

  9. Qiskit textbook: Shor's algorithm - Quantum Computing Stack …

    The Qiskit textbook shows the following circuit for implementing the phase $(\\frac{s}{r})$ estimation stage of Shor's algorithm for factorizing 15: My understanding is that the register of …
