ISC researcher Valentina Brosco coauthored an interesting research article published in ACS Applied Materials and Interfaces, C. Saggau et al.2D High-Temperature integration in Contact Printed Circuit Boards, ACS Appl. Mater. Interfaces 44, 51558 (2023).  The work paves the way to the realization of novel  printed circuits and devices integrating atomically thin high-Tc superconducting  films.

2D High-Temperature Superconductor Integration in Contact Printed Circuit Boards

Inherent properties of superconducting Bi2Sr2CaCu2O8+x films, such as the high superconducting transition temperature Tc, efficient Josephson coupling between neighboring CuO layers, and fast quasiparticle relaxation dynamics, make them a promising platform for advances in quantum computing and communication technologies.

Waveguide QED with Quadratic Light-Matter Interactions – PRX Quantum

ISC researcher S. Felicetti is the lead author of a research article now published in PRX Quantum, in collaboration with Aalto University (Helsinki) and the Institute of Fundamental Physics IFF-CSIC (Madrid): U. Alushi, T. Ramos, J.-J. G.-Ripoll, R. Di Candia, and S. Felicetti PRX Quantum 4, 030326 (2023).

Quadratic light-matter interactions are nonlinear couplings such that quantum emitters interact with photonic or phononic modes exclusively via the exchange of excitation pairs.… Read the rest

How to build a quantum Newton’s cradle

A quantum analogue of the popular “Newton’s cradle” toy has been proposed by a duo of physicists in Italy. Like momentum transferred in the toy, the team argues that it should be possible to achieve the nearly perfect transmission of a quantum wavefunction along a line of ultracold atoms in a 1D Bose–Einstein condensate. According to the pair, the work could help develop quantum-information systems that achieve high-quality wave transmission […]

Newton cradle

Newton’s cradle (Fig. 1) is a valuable paradigm of how physical mechanisms are concealed into nature. It is a device based on classical mechanics that demonstrates the conservation of momentum and energy. On the other hand, Quantum Mechanics has been shown to be one of most prolific sources of unexpected and hard-to-understand phenomena. Therefore, achieving a machine which is a paradigm for the quantum nature of a system is an engrossing challenge.… Read the rest
