Splet17. jun. 2013 · 15. Any reasonably sized RSA key will be broken by a quantum computer of comparable size using Shor's algorithm. Don't use RSA if you want to resist quantum computers, no matter the keysize. The only claim of a variant of RSA that survives are some slides by Bernstein mentioning a 2^43 bit RSA key consisting of 2^31 primes with 4096 … SpletShor’s Algorithm 5.1 Quantum Fourier Transform Quantum Fourier Transform is a quantum implementation of the discreet Fourier transform. You might be familiar with the discreet Fourier Trans-form or Fourier Analysis from the context of signal processing, linear algebra, or one of its many other applications. In short, Fourier Analysis is a tool to

SpletTools. In quantum computing, the quantum phase estimation algorithm (also referred to as quantum eigenvalue estimation algorithm ), is a quantum algorithm to estimate the phase (or eigenvalue) of an eigenvector of a unitary operator. More precisely, given a unitary matrix and a quantum state such that , the algorithm estimates the value of with ... SpletIt is known to be in BQP because of Shor's algorithm. The problem is suspected to be outside all three of the complexity classes P, NP-complete, and co-NP-complete. It is therefore a candidate for the NP-intermediate complexity class. If it could be proved to be either NP-complete or co-NP-complete, this would imply NP = co-NP, a very ... Splet07. feb. 2024 · I’m currently studying the Shor’s algorithm and am confused about the matter of complexity. From what I have read, the Shor’s algorithm reduces the … relegation 2. bl
