We implement a gate-tunable transmon (gatemon) qubit based on an InAs nanowire Josephson junction and identify distinct features in its microwave spectra that provide clear evidence of ultrastrong light–matter hybridization with a probing resonator [1]. These signatures include deviations of the measured anticrossing from the predictions of the Jaynes–Cummings model. […]

The laser stands as one of the most iconic examples of macroscopic coherence, fundamentally reshaping our understanding of light-matter interaction and underpinning key technologies of modern science. Yet lasing action is not exclusive to light: in principle, it can emerge in any bosonic system. The concept of the phonon laser, […]
Large Fock states are key nonclassical resources for bosonic quantum information, quantum-enhanced metrology, and the exploration of nonclassical dynamics in harmonic oscillators. However, preparing them high success probability remains challenging: deterministic protocols become increasingly control-intensive at large excitation number, while measurement-based strategies are naturally robust but suffer from rapidly decreasing […]
I will present experimental studies of one and two photon transitions in an array of Cs atoms trapped with a lattice of evanescent fields around an optical nanofiber, a waveguide. The transitions involved in the experiment are 6S1/2, 6P3/2 and 6D5/2. The single atom absorption is about 0.5% on the […]
We design a universal framework for fermionic quantum hardware that runs efficient variational algorithms to simulate generic many-body systems beyond the hardware’s native interactions. Our analysis shows that one can quantum simulate the ground-state properties of a broad class of gapless target Hamiltonians of local observables in a quantum evolution […]
In this talk, I would like to present our results on the interactions of quantum emitters coupled to the boundary of a two-dimensional photonic graphene. While 2D topological lattices typically support propagating edge modes, a zigzag termination in this system hosts a unique set of dispersionless, non-propagating edge modes that […]
Chirality is a fundamental property of nature. Enantiomers exhibit distinct properties in fields such as biomedicine, and achieving their efficient separation and detection remains a challenge of significant interest in physical chemistry. This report focuses on the enantioseparation of gaseous chiral molecules based on the cyclic three-level model, exploring corresponding […]
Photons typically interact with their environment only through emission and absorption. In this talk, I will describe a protocol in which microwave photons in superconducting resonators are coupled to an engineered reservoir; instead of removing particles from the system, this reservoir creates non-reciprocal transport between the system’s modes, leading to […]
