AI Article Synopsis
- The squeezing operation is introduced as a quantum gate that can work on various input states, not just Gaussian ones, in a deterministic and reversible way.
- For the first time, this operation is applied to non-Gaussian states, facilitating the conversion between a single-photon state (particle-like) and a superposition of coherent states (wave-like).
- The reliability of the squeezing gate helps maintain important properties of quantum states, paving the way for integrating discrete and continuous quantum protocols.
Article Abstract
We implement the squeezing operation as a genuine quantum gate, deterministically and reversibly acting "online" upon an input state no longer restricted to the set of Gaussian states. More specifically, by applying an efficient and robust squeezing operation for the first time to non-Gaussian states, we demonstrate a two-way conversion between a particlelike single-photon state and a wavelike superposition of coherent states. Our squeezing gate is reliable enough to preserve the negativities of the corresponding Wigner functions. This demonstration represents an important and necessary step towards hybridizing discrete and continuous quantum protocols.
