Nonetheless, when controlled, dissipation is an essential tool for manipulating quantum information: dissipation engineering enables quantum measurement, quantum-state preparation and quantum-state stabilization. The advances in quantum technologies, marked by improvements of characteristic coherence times and ...
However, we note that T(τ) is defined by the given dynamics of S and cannot therefore be related to an initial (dynamics-independent) temperature such as an equilibrium temperature assigned to the preparation of the state. Having calculated the heat and work exchanges by the system, it is ...

This became possible by the improved preparation and characterization techniques developed in the 80’s. Being eigenstates of a quasi-two-dimensional electronic system, quantum well states should show dispersion only with k‖, the wave vector component parallel to the film. They share this property...
Such an infinite-dimensional space is known as a “Hilbert space” and is characterized by a state vector always representing the pure state. During laboratory preparation of a quantum system, the position or energy of the constituent states is measured and thereafter the quantum state of a ...

“bonding”. While the initial thermal states’ preparation is relatively easy in our scheme, we still need resetting and timing control in the quantum cooling network. Similar to algorithmic cooling, timing and control can be achieved by using qubits at different thermalization rates. Another ...
we have been able to operate in the quantum regime of cavity optomechanics at room temperature. With a single-detector homodyne scheme countering TIN, we demonstrate optomechanical squeezing and conditional state preparation of displaced thermal states with single-phonon occupation, which is a prerequisit...
