Quantum computing, like conventional computing, is a technology to perform stepwise physical transformations on physical entities in such a way as to run algorithms. Because the steps in the physical quantum computing process are very different from those in conventional computing, quantum computers may be able to solve certain computational problems much more quickly than conventional computers. In addition, quantum computing, due to its potentially microscopically controllable processes, may provide insights into the fundamental nature of quantum processes and their probabilistic nature. In this seminar Dr. Edesess will present and conduct a discussion of the issues.

Quantum computing represents a revolutionary leap in computational power, leveraging the principles of quantum mechanics to process information in fundamentally new ways. Unlike classical computers, which use bits to represent data as 0s or 1s, quantum computers use quantum bits or qubits, enabling the phenomena of superposition and entanglement to perform complex calculations more efficiently (Nielsen & Chuang, 2010). This article explores the basic principles of quantum computing, the different models and algorithms that have been developed, and the current state of quantum hardware. The power of quantum computing lies in its ability to solve certain types of problems exponentially faster than classical computers. For instance, Shor's algorithm can factorize large integers in polynomial time, posing a significant threat to classical encryption methods (Shor, 1997). Similarly, Grover's algorithm provides a quadratic speedup for unstructured search problems, showcasing the potential for dramatic improvements in database search capabilities (Grover, 1996). These algorithms exemplify how quantum computing can revolutionize fields that rely on complex computations. Quantum hardware, however, is still in its nascent stage, with significant challenges to be overcome. Current quantum computers, such as those developed by IBM and Google, have demonstrated quantum supremacy but are limited by issues of qubit coherence and error rates (Arute et al., 2019). Quantum error correction and the development of more stable qubit technologies are critical areas of ongoing research (Preskill, 2018). Despite these challenges, recent advancements in quantum hardware and algorithms continue to drive the field forward, promising transformative impacts on industries such as cryptography, drug discovery, and artificial intelligence. As quantum computing continues to advance, it holds the promise of solving problems that are currently intractable for classical computers, paving the way for unprecedented technological and scientific advancements (Shor, 1997; Grover, 1996). This article provides a comprehensive overview of the current landscape of quantum computing, discussing its foundational principles, key algorithms, hardware challenges, and potential applications. By understanding these aspects, we can better appreciate the profound implications of quantum computing for the future of technology and science.

Some of the most important technical advances of the 20th century were enabled by decades of fundamental scientific exploration, whose initial purpose was simply to extend human understanding. This era marked the creation and widespread usage of “classical” computers, which represent information as bits – 0 and 1. Despite the continued computational advances we have experienced over the past century, there are still many important and relevant problems that “classical” computers cannot solve. We are witnessing rapid progress in a new computing paradigm – Quantum Computing. Quantum computing takes advantage of the laws of quantum mechanics found in nature and represents a fundamental change from classical information processing. Two properties of quantum behavior – superposition and entanglement – may allow quantum computers to one day address problems intractable for today’s conventional classical machines. During this talk, Dr. Gil will give an overview of quantum computing, what it means for the future of technology, and how we can separate hype from reality.

Abstract: Quantum computers work in a fundamentally different way from classical computers. Each qubit is in a superposition of 0 and 1 and can be used to store information. Quantum computers have the potential to revolutionize many industries. They can solve exponentially more difficult problems than conventional computers in seconds. Encryption is the process of turning plain text into ciphertext using a key. By measuring the quantum register we can find the marked number. Grover's algorithm can be used to solve a variety of problems related to finding an item in an unsorted database, such as cryptography, optimization, or machine learning. The main limitation of Grover's algorithm is that it is probabilistic. This means that there is a chance that the algorithm will not find the highlighted item after a certain number of iterations. However, the probability that the algorithm does not find the highlighted element decreases exponentially with the number of iterations. The Grover algorithm is a powerful quantum algorithm with many potential applications. However, it is still only a theoretical algorithm and has not been implemented on actual quantum computers. .. Many challenges must be overcome before the Grover algorithm can be used to solve real-world problems
