- Abstract: For efficient photovoltaic conversion, it is important to understand how
quantum entropy-related quantities evolve during the photovoltaic process. In
this study, using a double quantum dot (DQD) photocell model, we explored the
dynamic quantum entropy-related parameters during the photovoltaic output. The
findings demonstrate that the dynamic photovoltaic performance is compatible
with quantum entropy-related parameters with varying tunneling coupling
strengths, but at varied ambient temperatures, an opposing relationship is
discovered between them. Hence, some thermodynamic criteria may be used to
evaluate the photovoltaic process in this proposed photocell model. This work's
merits include expanding our understanding of photoelectric conversion from a
thermodynamic perspective as well as perhaps suggesting a new thermodynamic
approach to efficient photoelectric conversion for DQD photocells.

Wavepackets and the QED Origin of Bunched Electron Beam Superradiance [1.6285435061281421]
We show that the quantum state of the emitted photons is non-classical and does depend on the QEW shape.
This non-classicality originates from the shape dependent off-diagonal terms of the photon density matrix.
Our findings indicate that in the case of a modulated density QEWs beam, the phase of the off-diagonal terms of the photon state emitted by the modulated QEWs is the harbinger of bunched beam superradiance.

illumination [0.0]
Entangled photons produced by spontaneous parametric down-conversion have been of paramount importance for our current understanding of quantum mechanics and advances in quantum information.
We show that when a novel class of partially coherent Gaussian pump beams is considered, a distinct type of quantum state can be generated for which the amount of entanglement increases inversely with the degree of coherence of the pump beam.
This leads to highly incoherent yet highly entangled multi-photon states, which should have interesting consequences for photonic quantum information science.

Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols.
Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes.
We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
