In recent years, it has become possible to control and the measure the quantum states of the motion of macroscopic mechanical objects. Such efforts are motivated by both the study of fundamental science and the promise of new quantum technologies. I will give a brief overview of how recent advances in the fields of optomechanics and electromechanics have allowed us to explore the quantum...
In this talk I will describe our work on quantum networks of quantum emitters [1]. From the point of view of Quantum Optics, these are setups of quantum emitters (i.e. qubits or cavities that talk to qubits) connected by waveguides that transport photons among those nodes. This leads to a paradigm of quantum systems interacting through the exchange of retarded photons, creating what we call a...
I present the recent concept of first-order dissipative phase transitions, that can occur in meso- and even microscopic quantum systems.
One of the first examples of this phenomenon was the photon-blockade breakdown (PBB) effect, occurring most simply in the driven-dissipative Jaynes-Cummings model that contains only a single qubit. For PBB, an abstract thermodynamic limit has been...
Detecting and manipulating individual atoms with high fidelity is essential for quantum simulation, metrology and, with even more stringent requirements, for quantum computing. I will present our recent results on ultrafast single-atom imaging, based on alternated pulses of highly saturated light addressing the broad 1S0-1P1 transition in ytterbium. With this scheme, we achieve in-trap...
