Quantum motion of a squeezed mechanical oscillator attained via a optomechanical experiment
P. Vezio, A. Chowdhury, M. Bonaldi +7
We experimentally investigate a mechanical squeezed state realized in a parametrically-modulated membrane resonator embedded in an optical cavity. We demonstrate that a quantum cha…
Laser-induced frequency tuning of Fourier-limited single-molecule emitters
Maja Colautti, Francesco S. Piccioli, Pietro Lombardi +7
The local interaction of charges and light in organic solids is the basis of distinct and fundamental effects. We here observe, at the single molecule scale, how a focused laser be…
Probing quantum gravity effects with quantum mechanical oscillators
M. Bonaldi, A. Borrielli, A. Chowdhury +13
Phenomenological models aiming to join gravity and quantum mechanics often predict effects that are potentially measurable in refined low-energy experiments. For instance, modified…
Noise Sensing via Stochastic Quantum Zeno
Matthias M. Müller, Stefano Gherardini, Nicola Dalla Pozza +1
The dynamics of any quantum system is unavoidably influenced by the external environment. Thus, the observation of a quantum system (probe) can allow the measure of the environment…
Quantum signature of a squeezed mechanical oscillator
A. Chowdhury, P. Vezio, M. Bonaldi +7
Some predictions of quantum mechanics are in contrast with the macroscopic realm of everyday experience, in particular those originated by the Heisenberg uncertainty principle, enc…
Passively stable distribution of polarisation entanglement over 192 km of deployed optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +14
Quantum key distribution (QKD) based on entangled photon pairs holds the potential for repeater-based quantum networks connecting clients over long distance. We demonstrate long-di…
Conditional nonclassical field generation in cavity QED
Karsten Weiher, Elizabeth Agudelo, Martin Bohmann
We introduce a method for the conditional generation of nonclassical states of light in a cavity. We consider two-level atoms traveling along the transverse direction to the cavity…
Experimental test of exchange fluctuation relations in an open quantum system
Santiago Hernández-Gómez, Stefano Gherardini, Francesco Poggiali +4
Elucidating the energy transfer between a quantum system and a reservoir is a central issue in quantum non-equilibrium thermodynamics, which could provide novel tools to engineer q…
Measuring geometric phases with a dynamical quantum Zeno effect in a Bose-Einstein condensate
H. V. Do, M. Gessner, F. S. Cataliotti +1
A closed-trajectory evolution of a quantum state generally imprints a phase that contains both dynamical and geometrical contributions. While dynamical phases depend on the referen…
Calibrated quantum thermometry in cavity optomechanics
A Chowdhury, P Vezio, M Bonaldi +9
Cavity optomechanics has achieved the major breakthrough of the preparation and observation of macroscopic mechanical oscillators in peculiarly quantum states. The development of r…
Entangling macroscopic light states by delocalized photon addition
Nicola Biagi, Luca S. Costanzo, Marco Bellini +1
We present the experimental generation of tunable entanglement between distinct field modes by the delocalized addition of a single photon. We show that one can preserve a high deg…
Generation Engineering of Heralded Narrowband Colour Entangled States
A. Zavatta, M. Artoni, G. La Rocca
Efficient heralded generation of entanglement together with its manipulation is of great importance for quantum communications. In addition, states generated with bandwidths natura…
Noise spectroscopy of a quantum-classical environment with a diamond qubit
Santiago Hernández-Gómez, Francesco Poggiali, Paola Cappellaro +1
Knowing a quantum system's environment is critical for its practical use as a quantum device. Qubit sensors can reconstruct the noise spectral density of a classical bath, provided…
Fast and scalable quantum information processing with two-electron atoms in optical tweezer arrays
G. Pagano, F. Scazza, M. Foss-Feig
Atomic systems, ranging from trapped ions to ultracold and Rydberg atoms, offer unprecedented control over both internal and external degrees of freedom at the single-particle leve…

Silvia Viciani, Stefano Gherardini, Manuela Lima +2
Transport phenomena represent a very interdisciplinary topic with applications in many fields of science, such as physics, chemistry, and biology. In this context, the possibility…
In-field entanglement distribution over a 96 km-long submarine optical fibre
Sören Wengerowsky, Siddarth Koduru Joshi, Fabian Steinlechner +13
Techniques for the distribution of quantum-secured cryptographic keys have reached a level of maturity allowing them to be implemented in all kinds of environments, away from any f…
Noise-robust quantum sensing via optimal multi-probe spectroscopy
Matthias M. Müller, Stefano Gherardini, Filippo Caruso
The dynamics of quantum systems are unavoidably influenced by their environment and in turn observing a quantum system (probe) can allow one to measure its environment: Measurement…
Optimal control for one-qubit quantum sensing
F. Poggiali, P. Cappellaro, N. Fabbri
Quantum systems can be exquisite sensors thanks to their sensitivity to external perturbations. This same characteristic also makes them fragile to external noise. Quantum control…
Crossing Over from Attractive to Repulsive Interactions in a Tunneling Bosonic Josephson Junction
G. Spagnolli, G. Semeghini, L. Masi +9
We explore the interplay between tunneling and interatomic interactions in the dynamics of a bosonic Josephson junction. We tune the scattering length of an atomic K Bose-Ei…
