Non-Abelian braiding has attracted significant attention because of its pivotal role in describing the exchange behaviors of anyons–a candidate for realizing quantum logics. The input and outcome of non-Abelian braiding are connected by a unitary matrix which can also physically emerge as a geometric-phase matrix in classical systems. Hence it is predicted that non-Abelian braiding should have analogues in photonics, but a feasible platform and the experimental realization remain out of reach… 

Observation of Acoustic Non-Hermitian Bloch Braids and Associated Topological Phase Transitions.

Topological features embedded in ancient braiding and knotting arts endow significant impacts on our daily life and even cutting-edge science. Recently, fast growing efforts are invested to the

Hybrid topological photonic crystals

Photonic topological phases offering unprecedented manipulation of electromagnetic waves have attracted much research interest which, however, have been mostly restricted to a single band gap. Here,

Particle-Number Threshold for Non-Abelian Geometric Phases

When a quantum state traverses a path, while being under the influence of a gauge potential, it acquires a geometric phase that is often more than just a scalar quantity. The variety of unitary

Trapped boundary modes without a well-defined bulk gap

A boundary mode localized on one side of a finite-size lattice can tunnel to the opposite side which results in unwanted couplings. Conventional wisdom tells that the tunneling probability decays

Using a controllable quantum system to study another complicated or hard-to-control quantum system, quantum simulation provides a valuable tool to explore complex unknown quantum systems, which

Classical non-Abelian braiding of acoustic modes

Non-Abelian braiding is regarded as an essential process for realizing quantum logic. Its realizations in quantum systems often rely on the dynamic winding of anyons, which can be challenging to

Non-Abelian Braiding of Light.

This work demonstrates that non-Abelian Berry phases can arise when coherent states of light are injected into "topological guided modes" in specially fabricated photonic waveguide arrays, photonic analogues of topological zero modes in electronic systems.

Braiding photonic topological zero modes

A remarkable property of quantum mechanics in two-dimensional (2D) space is its ability to support "anyons," particles that are neither fermions nor bosons. Theory predicts that these exotic

Photonic implementation of Majorana-based Berry phases

This work experimentally realizes non-Abelian Berry phases with the topological characteristic that they are invariant under continuous deformations of their control parameters and implements a universal set of Majorana-inspired gates by performing topological and nontopological evolutions and investigates their resilience against perturbative errors.

Topological photonics is a rapidly emerging field of research in which geometrical and topological ideas are exploited to design and control the behavior of light. Drawing inspiration from the

Non-Abelian Thouless pumping in a photonic lattice

Non-abelian gauge fields emerge naturally in the description of adiabatically evolving quantum systems having degenerate levels. Here we show that they also play a role in Thouless pumping in the

Topological quantum computation has emerged as one of the most exciting approaches to constructing a fault-tolerant quantum computer. The proposal relies on the existence of topological states of

Experimental observation of non-Abelian topological charges and edge states.

This work opens the door towards characterization and manipulation of non-Abelian topological charges, which may lead to interesting observables such as trajectory-dependent Dirac/Weyl node collisions in two-dimensional systems, admissible nodal line configurations in three dimensions, and may provide insight into certain strongly correlated phases of twisted bilayer graphene.
