Optomechanical quantum sensors at room temperature

The research in cavity optomechanics has recently achieved a major breakthrough: the first observation of quantum phenomena in cryogenic, optically cooled mechanical resonators (i.e., actually in macroscopic objects), as well as in the electromagnetic field interacting with such resonators. These results open the way to the exploitation of optomechanical systems as quantum sensors.

Quantum Information Processing with Complex Media

The world’s most advanced quantum technologies rely for a large part on the control and manipulation of quantum states of light. From entanglement swapping to Boson sampling, linear optical devices such as beam splitters and integrated photonic circuits are essential for accomplishing key tasks in quantum communication and computation.

Towards Room Temperature Quantum Technologies

The goal of RouTe is to lay the foundations for a quantum technology that can operate at room temperature, thus taking a first major leap towards exploiting fundamental quantum phenomena in light-matter interaction for real-world applications. The enabling physical systems are organic materials that display quantum properties even at room temperature when coupled resonantly to cavity modes or plasmonic structures.

Long-range quantum bus for electron spin qubits in silicon

Electron spin qubits in silicon form a serious contender for the realization of a large-scale solid-state quantum computer. Solid-state realizations are considered scalable in general, but silicon spin qubits stand out due to their extremely long coherence times, compatibility with reliable and reproducible industrial fabrication techniques and the feasibility to integrate classical electronics.

Silicon Photonics for Quantum Fibre Networks

Nowadays secure communication is essential for exchange of sensitive information, while the security based on classical cryptography protocols cannot be absolutely guaranteed. Especially when a full-tolerant quantum computer will be available, the classical encryption and decryption methods will be no longer secure [1], posing a serious threat to cryptosystems. Quantum cryptography (QCy), a branch of Quantum Communications (QCs), has opened a new era in the security of information transmission.

Scaling Up quantum computation with MOlecular spins

SUMO aims to set the basis of a new architecture for quantum computation and simulation, in which information is encoded in molecular spin qubits that are read-out and communicate by coupling to a superconducting resonator. This technology has a high potential for robust scalability, based on the microscopic and reproducible nature of the molecules and on the possibilities they offer for embodying multiple qubits, which provide an extra dimension to increase computational resources and to implement noise-resilient logical qubits.

Topologically protected states in double nanowire superconductor hybrids

Topological quantum computing (TQC) is an emerging field with strong benefits for prospective applications, since it provides an elegant way around decoherence. The theory of TQC progressed very rapidly during the last decade from various qubit realizations to scalable computational protocols. However, experimental realization of these concepts lags behind. Important experimental milestones have been achieved recently, by demonstrating the first signatures of Majorana states which are the simplest non-Abelian anyons.

Trapped Atom Interferometers in Optical Lattices

The long-term vision of TAIOL project is to develop a novel class of quantum sensors based on trapped atom interferometry with performances that will overcome state of the art, and to extend their range of operation for high precision measurements in applied and fundamental physics.
