Generating Haar-Uniform Randomness Using Stochastic Quantum Walks on a Photonic Chip

Hao Tang et al.

Summary: This study successfully implements a two-dimensional stochastic quantum walk on an integrated photonic chip and demonstrates that the average of all distribution profiles converges to an even distribution, indicating 1-pad Haar-uniform randomness, as the evolution length increases. The study also shows that our two-dimensional array outperforms a one-dimensional array of the same number of waveguides in terms of convergence speed. This research demonstrates a scalable and robust method for generating Haar-uniform randomness and provides useful building blocks for future quantum information techniques.

Non-Abelian braiding on photonic chips

Xu-Lin Zhang et al.

Summary: The study successfully demonstrates non-Abelian braiding by controlling the geometric-phase matrix in a photonic chip, observing its key characteristics crucial for realizing quantum logics. The experiment showed the swapping of photon dwell sites in both classical-light and single-photon experiments, indicating the potential for implementing non-Abelian physics in photonics. The proposed on-chip photonic system opens up possibilities for studying non-Abelian physics and may lead to the development of next-generation non-Abelian photonic devices.

General Rules Governing the Dynamical Encircling of an Arbitrary Number of Exceptional Points

Feng Yu et al.

Summary: Researchers have proposed an on-chip photonic system that can dynamically encircle any number of exceptional points, revealing a robust state-switching rule for multistate systems and extending it to an infinite-period system where an exceptional line is encircled with outcomes at the Brillouin-zone boundary. The versatile platform is expected to uncover more physics related to multiple exceptional points and lines, leading to applications in multistate non-Hermitian systems.

Quantum Spatial Search in Two-Dimensional Waveguide Arrays

Claudia Benedetti et al.

Summary: Continuous-time quantum walks have been shown to efficiently perform spatial search of a marked site on graphs, but many of these graphs are difficult to realize in experiments. This study focused on CTQW spatial search on a planar triangular lattice, using numerical simulations and experiments with two-dimensional waveguide arrays. Results showed that the quantum walker had a higher probability of retrieving the marked site than the classical counterpart in an early time window.

Semiclassical Modified Redfield and Generalized Forster Theories of Exciton Relaxation/Transfer in Light-Harvesting Complexes: The Quest for the Principle of Detailed Balance

Thomas Renger

Summary: A conceptual issue in transfer theories using semiclassical descriptions of electron-vibrational coupling is the neglect of correlation between nuclear momenta and coordinates, leading to violations of detailed balance principles and equal transfer rate constants obtained uphill and downhill. Reorganization effects due to partial localization of excited states promote preferential downhill relaxation of excitation energy, but are too small to compensate for missing coordinate-momentum uncertainty in realistic spectral densities of light-harvesting antennae. Semiclassical variants of generalized Forster theory fulfill detailed balance principles in weakly coupled pigment domains, providing qualitatively correct transfer descriptions at lower computational costs compared to quantum counterparts.

Theoretical Study of the Spectral Differences of the Fenna-Matthews-Olson Protein from Different Species and Their Mutants

Zhe Huai et al.

Summary: This study investigated the spectral differences between Fenna-Matthews-Olson proteins from C. tepidum and P. aestuarii mutants, revealing that a single-point mutation near BChl 6 can significantly affect the absorption spectrum and excitonic structures of neighboring pigments. The results are consistent with previous experiments and indicate the critical role of protein scaffold in modulating optical properties.
