    What are quantum coherence and decoherence?

    Quantum coherence and decoherence are fundamental indications of how well a system of quantum objects -- atoms or other quantum particles -- maintains its relationships and how reliably the ongoing operation of that quantum system can be predicted over time.

  • What is a quantum circuit? Quantum vs. classical circuit

    Quantum circuits are systems consisting of logic gates that operate on quantum bits (qubits) to process information and perform calculations based on principles of quantum mechanics.

  • What is a quantum engineer?

    Quantum engineering is a technological field that focuses on the principles of quantum physics.

  • What is a quantum logic gate?

    A quantum logic gate is a basic quantum device that operates on a small number of quantum bits or qubits.

  • What is a quantum processing unit (QPU)?

    A quantum processing unit (QPU) is a hardware device that uses quantum mechanics -- such as superposition and entanglement-- to perform complex calculations on quantum information stored in quantum bits, or qubits.

  • What is qualitative data?

    Qualitative data is descriptive information that focuses on concepts and characteristics, rather than numbers and statistics.

  • What is quantum as a service? Definition and top providers

    Quantum as a service (QaaS), or quantum computing as a service, is a cloud-based way for organizations to access quantum computing technologies and capabilities more affordably through a third-party provider.

  • What is quantum entanglement and how does it work?

    Quantum entanglement is a foundational phenomenon in quantum mechanics where two or more particles become interconnected in such a way that the state of one particle instantly influences the state of the other, regardless of the distance separating them.

  • What is quantum error mitigation?

    Quantum error mitigation is a process used to reduce the impact of errors in quantum computing.

  • What is quantum machine learning? How it works

    Quantum machine learning (QML), also called quantum-enhanced machine learning, blends the computing power of quantum systems with the increasing computing demands of evolving machine learning models.

  • What is quantum technology? Use cases and future implications

    Quantum technology is a field of physics dedicated to developing new and innovative technologies based on the principles of quantum mechanics.
