Summary
A single quantum system, like a hydrogen atom, can transmit spatial orientation information. This is achieved by preparing the system in a specific quantum superposition state, enabling coordinate frame transmission.
Area of Science:
- Quantum Information Science
- Atomic Physics
- Quantum Measurement
Background:
- Quantum systems possess inherent properties that can encode information.
- Transmitting spatial information is crucial for quantum communication and computation.
- The rotation group is fundamental to describing quantum system symmetries.
Purpose of the Study:
- To demonstrate the transmission of a Cartesian coordinate frame using a single quantum system.
- To develop and present an algorithm for decoding this spatial information.
- To evaluate the fidelity of the transmitted coordinate frame.
Main Methods:
- Preparing a single quantum system (e.g., hydrogen atom) in a superposition of states.
- Utilizing states belonging to different irreducible representations of the rotation group.
- Developing a decoding algorithm to extract the coordinate frame information.
Main Results:
