Quantum Computing

A computing paradigm that uses quantum mechanical phenomena like superposition and entanglement to process information exponentially faster for certain problems.

Qubit

The fundamental unit of quantum information, capable of existing in a superposition of both 0 and 1 states simultaneously.

Superposition

A quantum mechanical property where a qubit exists in multiple states simultaneously until measured.

Quantum Entanglement

A phenomenon where two or more qubits become correlated such that the quantum state of one instantly influences the other regardless of distance.

Quantum Gate

A basic quantum circuit operation that manipulates one or more qubits, analogous to logic gates in classical computing.

Quantum Circuit

A sequence of quantum gates applied to qubits to perform a quantum computation.

Quantum Error Correction

Techniques for protecting quantum information from errors due to decoherence and other quantum noise sources.

Decoherence

The loss of quantum coherence when a quantum system interacts with its environment, causing errors in computation.

Quantum Noise

Random fluctuations in quantum systems that introduce errors and limit the accuracy of quantum computations.

NISQ

Noisy Intermediate-Scale Quantum — the current era of quantum computing with limited, error-prone qubits.

Fault-Tolerant Quantum Computing

Quantum computing systems that can continue to operate correctly even in the presence of errors.

Quantum Teleportation

A qubit implementation using superconducting circuits that exhibit quantum behaviour at extremely low temperatures.

The application of quantum mechanics and quantum computing to simulate chemical systems and molecular interactions.

A device that generates truly random numbers using quantum mechanical processes.

The quantum mechanical analogue of a classical random walk, used as a building block for quantum algorithms.

A quantum computing approach that uses the complex dynamics of quantum systems as a computational resource.

The intersection of quantum computing and machine learning, using quantum systems to enhance learning algorithms.

A metric for measuring the overall capability and error rates of a quantum computer.
