- 4. What is the Quantum Computing ? Quantum computing is a type of computation that harnesses quantum mechanics to process information. A computer that uses laws of quantum mechanics to perform massively parallel computing through superposition, entanglement, and decoherence. Instead of looking at quantum systems purely as phenomena to be explained as they are found in nature , they looked at them as systems that can be designed and user for computation. Richard Feyname Nobel Prize,1965
- 5. A qubit's ability to exist in multiple states at once, allowing quantum computers to perform parallel computations. Superposition Operations that manipulate qubits' states, similar to classical logic gates but capable of transforming qubits in more complex ways, such as creating superposition or entanglement. Quantum Gates A quantum phenomenon where qubits become linked, such that the state of one qubit is directly dependent on the state of another, regardless of distance Entanglement The process by which quantum states combine in such a way that probabilities can cancel out or amplify, influencing the outcome of computations. 1. Quantum Interference The fundamental unit of quantum information, representing 0, 1, or both simultaneously due to superposition Qubits What are the Concept in Quantum Computing ?

Aims to solve complex problems beyond classical limits (factoring, simulations). Increasing qubit counts and stability. Advancements in error correction. Growing investment and research. Works alongside classical computers (classical controls quantum).
- 8. Classical Computing Quantum Computing Used large-scale, multipurpose computer and devices Used by high-speed, quantum mechanics- based computers. Information is stored in bits. Information is stored in quantum bits. There is discrete number of possible states : 0 or 1 There is an infinite, continuous number of possible states. Calculations are deterministic, meaning repeating the same input result in the same output. Calculations are probabilistic, meaning there are multiple possible outputs to the same input. Data processing is carried out by logic and in sequential order. Data processing is carried out by quantum logic at parallel instances. Operations are defined by Boolean algebra Operations are defined by linear algebra over Hilbert space. Circuit behavior is defined by classical physics Circuit behavior is defined by quantum mechanics. Classical Computing VS Quantum Computing
- 9. Quantum Gate A quantum gate (or quantum logic gate) is a basic quantum circuit operating on qubits. . Quantum gates manipulate qubits, changing their quantum states. They are the basic building blocks of quantum algorithms. Due to the normalization condition every gate operation U has to be unitary: UU* = I The number of qubits in the input and output of the gate must be equal ; A gate which acts on n qubits is represented by 2 x 2 unitary matrix

- 11. ng Quantum Decoherence Qubit Scalability Qubits are extremely fragile and susceptible to environmental noise. This noise causes them to lose their quantum properties, leading to errors Building quantum computers with a large number of stable qubits is difficult. Maintaining coherence and control as the number of qubits increases is a major hurdle. Quantum Error Correction Hardware Reliability Errors are far more frequent in quantum computers than in Classical ones. Developing effective error correction techniques is complex and resource-intensive Quantum hardware is highly sensitive and prone to failures. Ensuring the reliability and stability of quantum systems is crucial. Challenges in Quantum Computing
