This work investigates the power-scaling potential of a holmium-doped yttrium lithium fluoride (Ho:YLF) chirped pulse amplifier (CPA) for pumping a mid-infrared zinc germanium phosphide (ZGP) optical parametric chirped pulse amplifier (OPCPA). The demonstrated double-pass Ho:YLF CPA delivers 2.05 μm pulses with 6 mJ pulse energy, 8 ps duration, and 5 kHz repetition rate, enabling OPCPA outputs...

Quantum simulators are platforms used to simulate classically intractable quantum systems. The ability to select an initial state, engineer interactions and select a measurement scheme enables a programmatic way to study quantum effects. Trapped atomic ions provide a versatile quantum simulation testbed due to their native all-to-all interactions, long coherence times and simple qubit state...

Barium ions have many interesting features suitable for scalable quantum information processing (QIP), such as metastable states with long lifetimes, enabling the manipulation of beyond-two-level systems, or qudits. Further, visible-wavelength transitions between Barium-ion energy levels enable programmable qubit/qudit manipulation using fiber-based optical modulators. Here, we discuss a QIP...

Single-photon emitters (SPEs) in hexagonal boron nitride (h-BN) offer a promising platform for quantum photonics, due to their robust room-temperature operation and compatibility with two-dimensional device architectures. Among them, blue-centers (B-centers) emitting near 436 nm have drawn special attention for their reproducibility and spectral purity [1]. Previous studies show how B-center...

Strong field science rapidly grew in the 1990s with the emergence of Ti:Sapphire based chirped pulse amplification (CPA) systems operating at 0.8 µm wavelength. Although many strong-field phenomena benefit from longer laser wavelengths [1, 2], to date this field has been largely restricted to near infrared range of 0.8 to 1 µm. The Fe:ZnSe-based CPA offers an efficient approach for reaching...

We present a theoretical framework to investigate high-harmonic generation (HHG) driven by Squeezed Coherent Thermal States (SCTS) of light. The study is motivated by the complementary roles played by squeezing and thermal fluctuations: while squeezing enhances quantum correlations, thermal photons introduce decoherence and noise, and their coexistence in a coherent background provides a rich...

In a quantum processor, quantum degrees of freedom such as the internal states of trapped atomic ions form a quantum bit of information, or qubit, and can be manipulated by laser beams. To improve the scalability of trapped-ion quantum computing, as well as to implement a broader range of algorithms, individual qubit state manipulation is a necessity. For high fidelity quantum gates, some of...

Optical nonreciprocity refers to the phenomenon where light in a system behaves differently depending on its direction of propagation. We aim to create a low-loss nonreciprocal phase-shifting element which has different optical path length depending on propagation direction. When placed in a ring cavity, the asymmetry would create a difference between the optical path lengths for the...

Can you character count: We study a minimalistic framework for the realization of photonic unitary transformations based on thin phase gratings interleaved with free-space propagation. The problem of realizing a unitary transformation on a given number of modes is expressed as a simple matrix model in transverse momentum space. This approach drastically reduces the number of system parameters...

We employ an isolated nitrogen–vacancy (NV) center as a quantum sensor to probe localized stress in a bulk diamond crystal and to measure magnetic fields, enabled by a monolithic inverse-designed photonic structure. This design allows efficient optical excitation of individual NV centers in a bulk sample and significantly enhances photon collection by engineering interference of the emitted...

We simulate the ultrafast optical response of an Indium Tin Oxide (ITO) thin film near its Epsilon-Near-Zero (ENZ) wavelength when excited by two femtosecond laser pulses. A temperature dependent Drude model captures the nonlinear optical behavior arising from electron heating in the thin ITO film. Initial results show that ultrafast heating from two pulses induces a complex dynamic grating...

The sudden removal of trapping potentials in Bose-Einstein condensates (BECs) gives rise to superfluid versions of hydrodynamic $\textit{dam-breaking}$ problems, leading to rich quantum dispersive-wave dynamics. Denoting $\Delta n/n_{0}$ as the initial difference in density between the two reservoirs on either side of the dam relative to the lower reservoir density $n_{0}$, we numerically and...

Recent advances in theoretical techniques allow high precision calculations for the high-lying Rydberg P-states of helium up to principal quantum number n = 35 [1].

Optical spectroscopy is a powerful tool for characterizing excitonic systems, ranging from solid-state photovoltaic materials to molecular light-harvesting complexes. Beyond the linear light–matter interaction, techniques such as pump-probe spectroscopy provide access to the nonlinear optical response of these systems. In the perturbative regime, the dominant contribution is the third-order...

Quadratic Unconstrained Binary Optimization problems (QUBOs) provide relevant testing grounds for quantum annealing platforms. However, mapping the logical QUBO onto a given quantum register is a known computational bottleneck. For Rydberg atom devices, the natural Unit-Disk topology arising from the Rydberg blockade mechanism limits the types of problems that can be naturally embedded on the...
