Quantum computing platforms based on superconducting qubits have emerged as one of the most promising candidates in the race to build a large scale quantum computer [1].
Controllability, standard chips fabrication techniques combined with the possibility of exploring unconventional hybrid systems [2] are well established advantages of superconducting qubits architectures as quantum...
A Josephson Travelling Wave Parametric Amplifier (TWPA) is a non-linear device which consists of a long array of repeating unit cells containing Josephson junctions. In our case the unit cell consists of a superconducting loop with three large (high critical current) and one small (low critical current) Josephson junctions (so-called SNAIL-cell - superconducting nonlinear asymmetric inductive...
In the last years, superconducting circuits have passed from being interesting physical devices to becoming one of the most promising contenders in the race towards the first fault-tolerant quantum computer [1].
In this context Quantum Non-Demolition (QND) read-out of superconducting qubits becomes an essential step in most computational operations and in protecting quantum information...
Supersolid is a state of matter in which coexist both a periodic modulation, characteristic of the solid state, and the ability of the superfluid to flow without any friction. Its theoretical prediction dates back to 1960s, but it was experimentally observed for the first time few years ago, in a dipolar quantum gas. This work is based on the idea of searching for coherent tunneling phenomena,...
We propose an estimation scheme based on the distribution of a single squeezed state among d interferometers to achieve highly sensitive estimation of multiple parameters. The scheme admits different implementations ranging from optical to atom interferometry. The fundamental component of our scheme is the “quantum circuit” (QC), a linear network that optimally distributes the squeezing...
Ultracold neutral atoms trapped in optical lattices and optical tweezers have emerged as groundbreaking tools to realize new systems for quantum information processing, precision measurements and quantum simulation. Optical tweezer arrays provide the ability to spatially manipulate ultracold atoms and control tunneling and interaction at the single-particle level, allowing the study of...
On-chip integration of deterministic single photon sources is of major significance in different emerging areas of quantum technologies like computing, sensing and so forth. In this talk, we are going to discuss some approaches towards integration of an organic-based single photon source, namely dibenzo-terrylene/anthracene nano-crystals to inorganic photonic structures to boost collection...
