Technology Glossary.

A finite sequence of well-defined instructions or rules designed to solve a specific problem or perform a computation.

The capability of a spacecraft or vehicle to determine its position, plan a path, and execute maneuvers without real-time human intervention, using onboard sensors and AI.

The duration over which a qubit maintains its quantum state before decoherence — the loss of quantum information to the environment — occurs.

A field of AI that trains computers to interpret and understand visual information from the world, such as images and video, using deep learning models.

Clustered Regularly Interspaced Short Palindromic Repeats — a revolutionary gene-editing technology that allows precise, targeted modifications to DNA sequences in living organisms.

A subset of machine learning that uses artificial neural networks with multiple layers (deep architectures) to model complex patterns in large datasets.

A distributed computing paradigm that brings computation and data storage closer to the sources of data, reducing latency and bandwidth usage.

A quantum mechanical phenomenon where two or more particles become correlated such that the quantum state of one instantaneously influences the other, regardless of distance.

Techniques used to protect quantum information from errors due to decoherence and noise, typically by encoding logical qubits across multiple physical qubits.

Energy produced by nuclear fusion reactions, where lighter atomic nuclei combine to form heavier nuclei, releasing enormous energy — the same process powering stars.

A medical approach that treats or prevents disease by introducing, altering, or replacing genetic material within a patient's cells.

A spacecraft propulsion method that generates thrust by accelerating ions using electric fields, offering extremely high fuel efficiency for deep-space missions.

A computational model inspired by the human brain, consisting of interconnected nodes (neurons) organized in layers that process information and learn patterns from data.

The branch of aerospace engineering and physics that studies the motion of objects in gravitational fields, used to plan spacecraft trajectories and orbital maneuvers.

The science and technology of generating, controlling, and detecting photons (light particles), with applications in communications, computing, and sensing.

A computing paradigm that uses quantum mechanical phenomena like superposition and entanglement to perform operations on data, enabling exponential speedups for certain problem classes.

The fundamental unit of quantum information — analogous to a classical bit, but capable of existing in a superposition of 0 and 1 simultaneously.

A machine learning paradigm where an agent learns to make decisions by taking actions in an environment to maximize cumulative reward through trial and error.

An engineered environment designed to support human life in space, incorporating life support, radiation shielding, artificial gravity, and self-sustaining resource cycles.

A quantum mechanical principle where a quantum system exists in multiple states simultaneously until measured, at which point it collapses to a single definite state.

An interdisciplinary field combining biology and engineering to design and construct new biological parts, devices, and systems — or to redesign existing natural biological systems.

A proposed approach to quantum computing that encodes information in topological states of matter, which are inherently resistant to local perturbations and decoherence.

A deep learning architecture based on self-attention mechanisms that processes sequential data in parallel, revolutionizing natural language processing and beyond.

The lowest possible energy that a quantum mechanical system may possess — even at absolute zero temperature, quantum systems retain residual energy due to the uncertainty principle.
