NISQ

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.

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.

Photonic Quantum Computing

Quantum computing using photons as qubits, manipulated through optical components.

The practical ability of a quantum computer to solve real-world problems faster or better than classical computers.

Accessing quantum computing resources remotely through cloud-based platforms and APIs.

An algorithm designed to run on a quantum computer, potentially solving certain problems faster than classical algorithms.

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

Computing architectures that combine quantum processors with classical computers to leverage the strengths of both.

System software designed to manage quantum computing resources, schedule operations, and handle error correction.

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

A secure communication method using quantum mechanics to generate and distribute encryption keys.
