Extensive efforts have been expended in develo** hybrid quantum systems to overcome
the short coherence time of superconducting circuits by introducing the naturally long-lived …

Light is usually confined in photonic structures with a band gap or relatively high refractive
index for broad scientific and technical applications. Here, a light confinement mechanism is …

Bound states in the continuum (BICs) provide a fascinating platform to route/manipulate
waves with ultralow loss by patterning low-refractive-index materials on a high-refractive …

We provide a detailed tutorial demonstrating how the principle of “bound states in the
continuum”(BICs) enables ultralow-loss guiding and routing of photons in photonic …

An all-optical scheme for simulating non-Markovian evolution of a quantum system is
proposed. It uses only linear optics elements and by controlling the system parameters …

Thin film lithium niobate (TFLN) has emerged as a promising platform for photonic integrated
circuits (PICs). However, the polarization crosstalk is usually inevitable owing to its …

We present a new optical scheme enabling the implementation of highly stable and
configurable non-Markovian dynamics. Here one photon qubit can circulate in a multipass …

In many physical systems, the interaction with an open environment leads to energy
dissipation and reduced coherence, making it challenging to control these systems …

Superposition of trajectories, which modify quantum evolutions by superposing paths
through interferometry, has been utilized to enhance various quantum communication tasks …

We show that non-Markovian open quantum systems can exhibit exact Markovian dynamics
up to an arbitrarily long time; the non-Markovianity of such systems is thus perfectly “hidden,” …
