TITLE

Engineering Squeezed Thermal Reservoirs: Harnessing Environmental Effects for Quantum Technologies

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.
