  Here, a physical formalism is proposed for an unconditional microwave quantum
teleportation of Gaussian states via two-mode squeezed states in lossy
environments. The proposed formalism is controllable to be used in both the
fridge and free space in case of entanglement between two parties survives.
Some possible experimental parameters are estimated for the teleportation of
microwave signals with a frequency of 5GHz based on the proposed physical
framework. This would be helpful for superconducting inter- and intra-fridge
quantum communication as well as open-air quantum microwave communication,
which can be applied to quantum local area networks (QLANs) and distributed
quantum computing protocols.
