Enhancing the d–Electrocatalytic Activity of MXene Through Defect Engineering

Carbon Energy, EarlyView.
Applications of MXene. ABSTRACT Due to their versatile and tunable surface and bulk chemistry, MXenes have great potential as electrocatalysts for batteries and supercapacitors. When compared with other electrocatalytic processes, in electrocatalytic reactions, MXenes could improve ion diffusion and charge transfer by either providing functional groups

Measurement of Lateral Resolution in Confocal Raman Spectroscopy Using Indium Arsenide Nanowires

Journal of Raman Spectroscopy, EarlyView.
Lateral resolution is a key performance parameter for confocal Raman spectroscopy. We propose a protocol using an indium arsenide nanowire reference sample to quantitatively measure the resolution. The suitability of the method has been demonstrated through an international comparison with 15 participants. ABSTRACT Lateral resolution is a key figure of

Quantum control, quantum information processing, and quantum-limited metrology with trapped ions

, 2005
We briefly discuss recent experiments on quantum information processing using trapped ions at NIST. A central theme of this work has been to increase our capabilities in terms of quantum computing protocols, but we have also applied the same concepts to ...

Deep‐UV Photonic Crystal Surface‐Emitting Lasers

Laser &Photonics Reviews, EarlyView.
The first deep‐UV photonic crystal surface‐emitting lasers (PCSELs) at 279 nm are demonstrated under pulsed optical pumping. The PCSELs have single‐mode emission with a 17‐pm linewidth and a divergence angle of less than 1∘$^{\circ }$. Experimental results highlight the impact of the filling factor choice on the lasing mode and the far‐field emission ...

Creation of higher order quantum NOON states using super-radiant emitters in the cavity [PDF]

AIP Advances
Quantum metrology promises the ability to greatly enhance conventional sensing. Inherently routed in quantum state manipulation and entanglement, it offers a pathway for sensing above and beyond what was previously thought possible.

Efficient Robust Spontaneous Parametric Down‐Conversion via Detuning Modulated Composite Segments Designs

Laser &Photonics Reviews, EarlyView.
Detuning modulated composite segmentation (DMCS) enables robust spontaneous parametric down‐conversion with sevenfold improved temperature stability compared to conventional designs, opening new possibilities for stable quantum photon sources. ABSTRACT Spontaneous parametric down conversion (SPDC) holds a pivotal role in quantum physics, facilitating ...

Unlocking Heisenberg Sensitivity with Sequential Weak Measurement Preparation [PDF]

Quantum
We propose a state preparation protocol based on sequential measurements of a central spin coupled with a spin ensemble, and investigate the usefulness of the generated multi-spin states for quantum enhanced metrology.

On the estimation of interaction parameters in weak measurements

, 2010
Since weak measurements are known to produce measurement values that can be much larger than the maximal eigenvalues of the measured observable, it is an interesting question how this enhancement of the measurement signal relates to the sensitivity of ...

Advances in Position‐Momentum Entanglement: A Versatile Tool for Quantum Technologies

Laser &Photonics Reviews, EarlyView.
Position–momentum entanglement constitutes a high‐dimensional continuous‐variable resource in quantum optics. Recent advances in its generation, characterization, and control are reviewed, with emphasis on spontaneous parametric down‐conversion and modern measurement techniques.
