'''Quantum Computing''' is the computational paradigm in which information is represented in quantum-mechanical states — qubits in superposition rather than classical bits — enabling certain classes of problems (factoring, unstructured search, simulation of quantum systems, certain optimization tasks) to be solved with exponential or polynomial speedup over classical approaches.

Within the [[FusionGirl]] [[Tech Levels]] continuum, Quantum Computing is a defining capability of the [[Holo Tech]] / [[Magnetospheric Age]] / [[Holographic Age]] tier and continues to deepen through [[Super Tech]], [[Hyper Tech]], and into [[Quantum Tech]] cross-cutting applications. It sits at the intersection of [[Spintronics]], [[Topological Quantum Computers|topological systems]], [[Plasmoid Tech]] resonant-state engineering, and post-quantum-cryptographic considerations relevant to [[PsiNet]] and adjacent secure-communications infrastructure.

== Foundational Principles ==
Quantum Computing rests on three operational primitives drawn from mainstream quantum mechanics:

* '''Superposition.''' A qubit exists in a coherent linear combination of |0⟩ and |1⟩ basis states until measurement collapses it. ''N'' qubits represent a superposition of 2''ⁿ'' classical states simultaneously.
* '''Entanglement.''' Qubits in an entangled state share correlated measurement outcomes that cannot be reduced to independent classical descriptions. Entanglement is the principal resource by which quantum speedup is realised over classical computation.
* '''Interference.''' Quantum algorithms are designed so that probability amplitudes for correct answers reinforce while amplitudes for incorrect answers cancel — analogous to constructive and destructive wave interference at the amplitude level.

== Qubit Modalities ==
Multiple physical platforms implement qubits, each with characteristic trade-offs:

* '''[[Superconducting Qubits]].''' Josephson-junction-based; current commercial leaders (IBM, Google). Operate at millikelvin temperatures.
* '''[[Trapped Ions]].''' Long coherence times; slower gate speeds; IonQ, Quantinuum.
* '''[[Photonic Qubits]].''' Linear-optical and integrated-photonic approaches; room-temperature operation; PsiQuantum, Xanadu.
* '''[[Spintronic Qubits]].''' Electron-spin-based; substantial overlap with [[Spintronics]] research. See [[Spintronics]] for cross-discipline detail.
* '''[[Topological Quantum Computers|Topological Qubits]].''' Based on [[Non-Abelian Anyons]] and topologically-protected states; principal candidate for intrinsically fault-tolerant computation; cluster overlap with [[Quasiparticles]] and [[Fractional Quantum Hall Effect]] research.
* '''[[Neutral Atoms]].''' Optical-tweezer arrays; rapidly improving platform.

== Algorithms of Note ==
* '''Shor's algorithm.''' Integer factoring in polynomial time; basis for the [[Post-Quantum Cryptography]] migration imperative.
* '''Grover's algorithm.''' Quadratic speedup on unstructured search.
* '''Quantum simulation.''' Native simulation of quantum-chemistry and condensed-matter systems; principal near-term application domain.
* '''Variational Quantum Eigensolver (VQE)''' and '''Quantum Approximate Optimization Algorithm (QAOA)'''. Hybrid classical-quantum approaches suited to noisy intermediate-scale quantum (NISQ) hardware.

== Quantum Computing in the FusionGirl Continuum ==

=== Holo Tech / Holographic Age ===
The [[Holo Tech]] tier marks the first widespread integration of Quantum Computing into civilian and infrastructure systems, alongside [[Holographic Interfaces]] and [[Magnetosphere Manipulation]]. Quantum-accelerated rendering, simulation, and AI inference become routine.

=== Super Tech and Beyond ===
[[Super Tech]] integrates quantum computing with [[Plasmoid Tech]] coherent-state engineering, enabling room-temperature large-scale quantum systems. [[Hyper Tech]] sees the emergence of [[Quantum Printing]] and quantum-substrate biological interfaces.

=== Cryptographic Implications ===
The cryptographic relevance is substantial: classical RSA / ECDSA-based public-key systems become insecure under sufficiently capable quantum adversaries. The [[FusionGirl]] secure-communications stack (see [[PsiNet]], [[Comm Tech]]) is designed around [[Post-Quantum Cryptography]] (PQC) primitives — lattice-based, hash-based, and code-based schemes resistant to known quantum algorithms.

=== Defensive Posture ===
[[C.A.B.A.L.]] and [[Malefic AI]]-class adversaries are projected to develop quantum-computing capabilities; the [[Earth Alliance]] defensive posture combines PQC migration with [[Psionic Communications|psionic-channel]] alternatives that are not vulnerable to electromagnetic-substrate quantum attacks.

== Adjacent Concepts ==
[[Spintronics]], [[Quasiparticles]], [[Topological Quantum Computers]], [[Non-Abelian Anyons]], [[Quantum Tech]], [[Quantum Conductors]], [[Post-Quantum Cryptography]], [[Holo Tech]], [[Super Tech]], [[Holographic Age]].
