Query: A high fidelity heralded squeezing gate   A universal squeezing gate capable of squeezing arbitrary input states is
essential for continuous-variable quantum
computation~\cite{PRA79062318,PRL112120504}. However, in present
state-of-the-art techniques~\cite{PRA90060302,PRL106240504}, the fidelity of
such gates is ultimately limited by the need to create squeezed vacuum modes of
unbounded energy. Here we circumvent this fundamental limitation by using a
heralded squeezing gate. We propose and experimentally demonstrate a squeezing
gate that can achieve near unit fidelity for coherent input states. In
particular, for a target squeezing of \SI{2.3}{\dB}, we report a fidelity of
\SI{98.5}{\%}. This result cannot be reproduced by conventional schemes even if
the currently best available squeezing of \SI{15}{\dB}~\cite{PRL117110801} is
utilised when benchmarked on identical detection inefficiencies. Our technique
can be applied to non-Gaussian states and provides a promising pathway towards
high-fidelity gate operations and fault-tolerant quantum computation.
