Nettet4. mar. 2016 · We have presented the realization of Kitaev’s vision of Shor’s algorithm based on scalable building blocks with three-digit resolution to factor N = 15, using bases {2, 7, 8, 11, 13}. To do this, we successfully employed a semiclassical QFT combined with single-qubit readout, feed-forward behavior, and qubit recycling. NettetWith this knowledge, we can now look at a general idea of how Shor's Algorithm works. Shor's Algorithm Method 1. Select a random integer, g, such that 1 g N. This will be our initial guess for one of the prime factors of N. 2. Find the highest common factor of g and N [i.e. gcd(g,N)] using the Euclidean algorithm. 3. completely free giftcard to shop online

Nettet3. nov. 2024 · Shor's algorithm can be used to factorize a large (semi)prime N by reducing the task to period-finding of a function f ( x) = x a mod N. This is done by creating an equal superposition over all pairs of a i and f ( x) = x a i for a random x, then measuring f ( x) causing the superposition to collapse into all a i for which f ( x) is our ... NettetWe can transform the code into a recurrence relation as follows. T(n) = {a if n ≤ 2 b + T(n − 1) otherwise. When n is 1 or 2, the factorial of n is n itself. We return the result in … Nettet18. nov. 2024 · $\begingroup$ Typically, there are two approaches to demonstrating Shor's algorithm: (i) build up from phase estimation, using eigenvector inputs, then make the jump to an input that is a superposition of eigenvectors.

Unfortunately we can't use a quantum computer to do it. But the numbers are small enough that we can brute-force the period finding classically: def brute_force_find_period(B, R): n = 1 t = B while t != 1: t *= B t %= R n += 1 return n.
