vocabulary:
  domain: Amazon Braket
  description: >-
    Taxonomy and vocabulary for Amazon Braket covering quantum computing,
    quantum hardware, circuits, hybrid algorithms, and quantum information science.

  concepts:
    - term: Quantum Computer
      definition: >-
        A computing device that uses quantum mechanical phenomena such as
        superposition, entanglement, and interference to perform computations
        that are infeasible for classical computers.

    - term: QPU
      label: Quantum Processing Unit
      definition: >-
        Physical quantum hardware that executes quantum circuits using
        superconducting qubits, trapped ions, neutral atoms, or photonic systems.

    - term: Qubit
      definition: >-
        The fundamental unit of quantum information. Unlike classical bits
        (0 or 1), qubits can exist in superposition of both states simultaneously.

    - term: Superposition
      definition: >-
        A quantum mechanical property where a qubit can exist in multiple
        states simultaneously until measured, enabling parallel computation.

    - term: Entanglement
      definition: >-
        A quantum phenomenon where two or more qubits become correlated such
        that the state of one instantly influences the state of another,
        regardless of distance.

    - term: Quantum Gate
      definition: >-
        A basic quantum computing operation that manipulates qubit states,
        analogous to classical logic gates. Examples include H (Hadamard),
        CNOT (Controlled-NOT), and T gates.

    - term: Quantum Circuit
      definition: >-
        A sequence of quantum gates applied to qubits to implement a
        quantum algorithm, analogous to a classical program.

    - term: Quantum Task
      definition: >-
        A single quantum circuit or annealing problem submitted to an Amazon
        Braket device for execution, with results stored in Amazon S3.

    - term: Hybrid Job
      definition: >-
        A managed compute workload that combines classical algorithms running
        on EC2 with quantum circuit execution on QPU or simulator devices,
        with priority QPU access over standalone tasks.

    - term: Quantum Simulator
      definition: >-
        A classical computer program that emulates quantum hardware behavior
        for testing and development. Braket offers SV1 (state vector), DM1
        (density matrix), and TN1 (tensor network) simulators.

    - term: Shots
      definition: >-
        The number of times a quantum circuit is executed and measured.
        More shots reduce statistical uncertainty in measurement outcomes.

    - term: OpenQASM
      label: Open Quantum Assembly Language
      definition: >-
        An open-source quantum circuit description language used to specify
        quantum programs in Amazon Braket tasks.

    - term: VQE
      label: Variational Quantum Eigensolver
      definition: >-
        A hybrid quantum-classical algorithm for finding the ground state
        energy of molecules, widely used for quantum chemistry simulation.

    - term: QAOA
      label: Quantum Approximate Optimization Algorithm
      definition: >-
        A hybrid quantum-classical algorithm for solving combinatorial
        optimization problems using quantum circuits.

    - term: Quantum Annealing
      definition: >-
        A metaheuristic optimization technique that uses quantum fluctuations
        to find the global minimum of an objective function.

    - term: Noise
      definition: >-
        Unwanted perturbations in quantum hardware that cause errors in
        qubit states and gate operations, a major challenge for near-term QPUs.

    - term: NISQ
      label: Noisy Intermediate-Scale Quantum
      definition: >-
        The current era of quantum hardware with 50-1000 qubits that are
        subject to noise and lack full error correction.

    - term: Pulse Control
      definition: >-
        Low-level control of quantum hardware using microwave or laser pulses
        that implement quantum gates, enabling hardware-level optimization.
