  Continuous variable entangled radiation, known as Einstein-Podolsky-Rosen
(EPR) states, are spatially separated quantum states with applications ranging
from quantum teleportation and communication to quantum sensing. The ability to
efficiently generate and harness EPR states is vital for advancements of
quantum technologies, particularly in the microwave domain. Here, we introduce
a kinetic inductance quantum-limited amplifier that generates stationary
path-entangled microwave radiation. Unlike traditional Josephson junction
circuits, our design offers simplified fabrication and operational advantages.
By generating single-mode squeezed states and distributing them to different
ports of a microwave resonator, we deterministically create distributed
entangled states at the output of the resonator. In addition to the
experimental verification of entanglement, we present a simple theoretical
model using a beam-splitter picture to describe the generation of
path-entangled states in kinetic inductance superconducting circuits. This work
highlights the potential of kinetic inductance parametric amplifiers, as a
promising technology, for practical applications such as quantum teleportation,
distributed quantum computing, and enhanced quantum sensing. Moreover, it can
contribute to foundational tests of quantum mechanics and advances in
next-generation quantum information technologies.
