We demonstrate encoding quantum dynamics into a quantum system

Area of Science:

  • Quantum Information Science
  • Quantum Computing
  • Quantum Dynamics

Background:

  • Quantum systems can store and process information.
  • Quantum transformations are fundamental operations in quantum computing.

Purpose of the Study:

  • To develop a method for encoding quantum dynamics into a quantum system's state.
  • To enable stochastic execution of stored quantum transformations on other systems.

Main Methods:

  • Encoding quantum dynamics within the state of a quantum system.
  • Utilizing the encoded state to stochastically perform transformations.

Main Results:

  • The probability of failure decreases exponentially with the number of qubits used for storage.

Related Experiment Videos

  • The scheme's optimality is discussed.

    • Conclusions:

    • This method allows for the storage and later stochastic application of quantum transformations.
    • Applications include programmable quantum gates and quantum transformation teleportation.
