Upper bound to optical forces through the multipolar control of optical beams

Enrique Ayllón-García, Iker Gómez-Viloria, Quimey Pears Stefano +6

Optical tweezers enable the manipulation of microscopic objects using light, yet the fundamental limits to the optical forces that can be exerted on matter remain unknown. Here we…

Controlling the centre of mass motion of levitated particles using structured wavefronts

Shah Jee Rahman, Quimey Pears Stefano, Angel Cifuentes +5

Optically levitated particles have great potential to form the basis of novel quantum- enhanced sensors. These systems are very well suited for inertial sensing, as the particles a…

Experimental characterization of quantum processes: a selective and efficient method in arbitrary finite dimension

Quimey Pears Stefano, Ignacio Perito, Juan José Miguel Varga +2

The temporal evolution of a quantum system can be characterized by quantum process tomography, a complex task that consumes a number of physical resources scaling exponentially wit…
