Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide
Advanced Functional Materials, EarlyView.An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Witnessing effective entanglement over a 2km fiber channel
, 2010 We present a fiber-based continuous-variable quantum key distribution system. In the scheme, a quantum signal of two non-orthogonal weak optical coherent states is sent through a fiber-based quantum channel. The receiver simultaneously measures conjugate

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...

Computational distinguishability of degradable and antidegradable channels [PDF]
Quant. Inf. Comp. 10 (2010) 735-746, 2009 A channel is degradable if there exists a second channel that maps the output state of the channel to the environment state. These channels satisfy the property that the output state contains more information about the input than the environment does.

Advanced Functional Materials, EarlyView.This review synthesizes the evolution of radiative heat transfer, emphasizing the transition from far‐field to near‐field regimes. Traditional frameworks, such as Planck's law, are revisited alongside modern innovations like fluctuational electrodynamics. Applications span nanoscale thermal management, energy harvesting, and thermophotovoltaic systems.
