The spin degree of freedom of an electron or a nucleus is one of the most basic properties of
nature and functions as an excellent qubit, as it provides a natural two-level system that is …

Interactions between light and matter play an instrumental role in spectroscopy, sensing,
quantum information processing and lasers. In most of these applications, light is considered …

Light–matter interactions at the single-particle level have generally been explored in the
context of atomic, molecular and optical physics. Recent advances motivated by quantum …

By developing a gain-embedded cavity magnonics platform, we create a gain-driven
polariton (GDP) that is activated by an amplified electromagnetic field. Distinct effects of gain …

We study a quantum heat engine at strong coupling between the system and the thermal
reservoirs. Exploiting a collective coordinate mapping, we incorporate system-reservoir …

We theoretically investigate charge transport through electronic bands of a mesoscopic one-
dimensional system, where interband transitions are coupled to a confined cavity mode …

Quantum technology promises revolutionizing applications in information processing,
communications, sensing and modelling. However, efficient on-demand cooling of the …

Superconducting electronic devices have reemerged as contenders for both classical and
quantum computing due to their fast operation speeds, low dissipation, and long coherence …

We present an experimental study of flux-and gate-tunable nanowire transmons with state-of-
the-art relaxation time allowing quantitative extraction of flux and charge noise coupling to …

Superconducting coplanar-waveguide resonators that can operate in strong magnetic fields
are important tools for a variety of high-frequency superconducting devices. Magnetic fields …
