Quantum-Kit: Simulating Shor's Factorization of 24-Bit Number on Desktop

Abstract: Quantum-Kit is a graphical desktop application for quantum circuit simulations. Its powerful, memory-efficient computational engine enables large-scale simulations on a desktop. The ability to design hybrid circuits, with both quantum and classical bits and controls, is employed to demonstrate Kitaev's approach to Shor's factorization algorithm. For the first time, Shor's factorization of a 24-bit integer is simulated with Quantum-Kit in a mere 26 minutes on a modest desktop with Intel Core i5 7400T, 2.4GHz and12GB RAM. While the largest number factorized so far has been a 20-bit integer, requiring 60 qubits and a supercomputer, the hybrid circuit functionality allows the same number to be factorized using Kitaev's trick with only 21 qubits, in 2.3 minutes, on a desktop. Furthermore, conventional Shor's algorithm for a 13-bitinteger with 39 qubits is shown to be 35x faster with Quantum-Kit.
