Study Notes
Introduction to Quantum Computing
- Quantum computing leverages quantum mechanics to solve complex problems intractable for classical computers
- Key principles include superposition, entanglement, and interference
- Quantum computers use qubits (quantum bits) instead of classical bits
- Qubits can exist in multiple states simultaneously (superposition)
- Qubits can be linked together via entanglement to perform complex calculations
- These principles lead to a potential for exponential speedup over classical computers
How Quantum Computers Work
- Quantum computers consist of three main components:
- A classical computer for programming and controlling qubits
- Hardware that allows communication between the computer and qubits
- Qubit storage unit
- Qubits (electrons or photons) store and transfer information
- Quantum computers process information through a series of operations specified by a quantum algorithm
- Measurements are required to extract the result from a quantum computer
- The quantum state is sensitive to environmental factors (decoherence)
Quantum Processor
- A quantum processor is the core component of a quantum computer
- Different types of quantum processors exist, including photonic, spintronic, and ion trap processors
- Quantum processing units (QPUs) contain qubits
- Quantum computing chips can employ various computing models, including quantum annealing, quantum circuit, and quantum logic gate-based approaches
- Advanced quantum processors, like IBM's Osprey, feature a significant number of qubits
Quantum Circuits
- Quantum circuits are fundamental models for quantum computation that utilize qubits and quantum gates
- Quantum circuits are composed of quantum gates and an n-qubit register
- Quantum gates manipulate the quantum state of qubits
- Initialisation, switching, and rotation are crucial steps within the circuits
Applications of Quantum Computing
- Quantum computing has potential applications in various fields, including finance, drug discovery, optimization, supply chains, climate modelling, and more
- Quantum computing could enhance financial portfolios, develop improved fraud detection, improve trading simulators, and revolutionize chemical and drug discovery processes
- It is also relevant to other applications, like improving supply chain logistics and weather models, through speedup and accuracy
Challenges in Quantum Computing
- Qubit stability (decoherence): Qubits are extremely sensitive to external disturbances, leading to decoherence, which is a primary challenge for quantum computer functionality
- Scalability in handling a large number of qubits: Building large, stable quantum computers is a significant technological hurdle
- Fault tolerance: Quantum computers are prone to errors due to qubit imperfections
- Hardware and software development requires advancement and optimization
- The expense of building and maintaining quantum computers remains a major financial hurdle
Future of Quantum Computing
- Significant advances are needed to make quantum computing more accessible and practical
- The future of quantum computing depends on overcoming the current challenges, especially regarding scalability, fault tolerance, error correction, and cost-effectiveness
- Research, development, and infrastructure are key drivers of progress in quantum technologies
