Abstract

his study explores the application of quantum computing in solving complex mathematical problems through the utilization of Grover's Algorithm. Grover's Algorithm, renowned for its efficiency in unstructured search, has been adapted for various mathematical applications requiring rapid solution searches within large solution spaces. In this study, we implement Grover's Algorithm on a quantum computing platform to address a range of complex mathematical problems, including nonlinear equations and combinatorial optimization. Experimental results demonstrate that Grover's Algorithm significantly reduces computational time compared to classical methods, highlighting the immense potential of quantum computing in advanced mathematics. These findings pave the way for the development of more sophisticated quantum algorithms and their applications across science, engineering, and technology domains.

Abstract

Dalam bidang sains dan teknik, permasalahan yang berkaitan dengan penentuan turunan sering dijumpai dalam berbagai kajian. Namun, tidak semua turunan fungsi dapat diselesaikan secara analitik karena bentuk persamaannya yang kompleks. Oleh sebab itu, diperlukan pendekatan numerik untuk memperoleh nilai turunan secara hampiran. Beberapa metode yang umum digunakan dalam penyelesaian turunan numerik antara lain metode beda maju, metode beda mundur, dan metode beda pusat. Penelitian ini bertujuan untuk membandingkan tingkat keakuratan ketiga metode tersebut dalam menentukan nilai turunan suatu fungsi. Nilai turunan yang diperoleh kemudian dibandingkan dengan nilai turunan eksaknya sehingga dapat diketahui besar kesalahan (error) yang dihasilkan oleh masing-masing metode.

Abstract

Persamaan linier merupakan persamaan aljabar yang setiap sukunya mengandung konstanta atau hasil perkalian konstanta dengan variabel tunggal. Sistem persamaan linier dapat diselesaikan menggunakan metode numerik, yang secara umum dibedakan menjadi metode langsung dan metode iteratif. Metode langsung, yang dikenal sebagai metode eksak, meliputi metode invers dan berbagai teknik dekomposisi matriks, sedangkan metode iteratif menghasilkan solusi melalui proses pendekatan berulang. Artikel ini bertujuan untuk membahas penyelesaian persamaan linier secara numerik dengan menggunakan metode iteratif, khususnya metode Jacobi dan metode Gauss–Seidel. Kedua metode tersebut dipilih karena sering digunakan dalam penyelesaian sistem persamaan linier berukuran besar serta memiliki karakteristik konvergensi yang berbeda. Hasil kajian menunjukkan bahwa metode Gauss–Seidel umumnya memiliki tingkat konvergensi yang lebih cepat dibandingkan metode Jacobi.
