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

The transfer of quantum states between qubits using entanglement and classical communication.

A quantum computing approach that finds the lowest energy state of a system, useful for optimisation problems.

Using quantum computers to model and simulate quantum systems that are intractable for classical computers.

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

A proposed network infrastructure that uses quantum signals for ultra-secure communication and distributed quantum computing.

A quantum search algorithm that provides quadratic speedup for searching unsorted databases.

A hybrid quantum-classical algorithm for finding the ground state energy of molecular systems.

Using quantum mechanical effects to achieve measurement sensitivities beyond what classical sensors can achieve.

Software that translates high-level quantum algorithms into sequences of quantum gates executable on specific hardware.
