Abstract:

Squeezed thermal reservoirs enable directional dissipation and effective noise suppression, but conventional implementations often rely on complex setups such as injected squeezed light or driven nonlinear interactions. In this talk, I will present a fully passive method for engineering squeezed thermal reservoirs using only linear coupling to a lossy mode in a standard thermal environment. This approach generates tunable, anisotropic fluctuations in phase space, allowing tailored control over system dynamics without active modulation or nonlinearity. I will illustrate two representative applications to both qubits and bosonic modes, highlighting the approach’s versatility and practical relevance. This passive method provides a resource-efficient and experimentally accessible framework that can support future advances in dissipative squeezing, quantum simulations, and thermodynamic studies.
