It is clearly desirable to cool down or purify a qubit at the fastest rate possible to make it suitable for tasks of quantum information processing. The standard, straightforward way of cooling a system such as a qubit is by equilibrating this system with a cold bath. But can one cool qubits faster than their equilibration time?
Quantum phenomena are expected to play an increasing role in future technologies. Special attention must hence be paid to omnipresent decoherence effects.
Environment effects generally hamper or completely destroy the “quantumness” of any complex device. Particularly fragile against environment effects is quantum entanglement (QE) in multipartite systems.
We investigate the possibilities of quantum information processing transfer and storage in hybrid systems comprised of diverse blocks integrated on chips
We develop novel NMR and optical methods aimed at employing dynamical control to acquire information on the bath spectrum and tis coupling to the system. The focus on methods that venture beyond the weak-coupling limit.
We have focused on two topics related to BEC:
Quantum optics methods have been employed to discover novel, powerful mechanisms for:
