Geetanjali Yadav,Ramkrishna Sen show different methods of reduction of discrete logarithm problem over prime fields to the QUBO problem. In the best case, if . is the bitlength of a characteristic of the prime field ., there are required approximately . logical qubits for such reduction. We present practical attacks on discrete l

Sustainable Financing for ESG Practices,pressive sensing requires finding the most sparse solution to an underdetermined linear system, which is an NP-hard problem and as a consequence in practise is only solved approximately. In our work we restrict ourselves to the compressive sensing problem for the case of binary signals. For that cas

These memory requirements are a barrier for simulating large models or long time spans. We have created a nonstandard automatic differentiation technique that can compute gradients needed by G

In particular, QA is suitable for problems that can be formulated as a Quadratic Unconstrained Binary Optimization (QUBO) problem, such as SAT, graph colouring and travelling salesman. With commercially available QA hardware, like that offered by D-Wave Systems (D

Joseph H. L. Chan,Theresa Y. M. Chanowers. Researchers have developed algorithms that allow quantum computers to hack into information security concepts that were previously considered difficult, if not impossible, including asymmetric key cryptography and elliptic curve cryptography. Studies have been done to focus on improving secur

However, these gates cannot be physically implemented in quantum hardware and therefore they need to be decomposed into many smaller elementary gates. In this work we analyse previously proposed circuit constructions for MC
