Remote state preparation stands as a crucial protocol for transmitting quantum states, facilitating the remote preparation and manipulation of quantum states through distributed quantum entanglement. In recent times, notable progress has been achieved in remote state preparation, encompassing the remote preparation of single qubits, continuous-variable qubits, squeezed states, non-Gaussian states, and optical cat states. This paper provides a concise overview of the principles behind remote state preparation, highlighting the research advancements and developmental trends in both discrete and continuous variable systems.
