A particle-like object with a quarter of an electron's charge is the latest find in a hotbed of quantum-physical experimentation, the fractional quantum Hall fluid. Its significance is more than esoteric.

Anomalous quantum Hall effect: An incompressible quantum fluid with fractionally charged excitations
This Letter presents variational ground-state and excited-state wave functions which describe the condensation of a two-dimensional electron gas into a new state of matter.

Some experts think that a quantum computation could be plaited like a skein of string. And now they may have found the sorts of string they need, finds Liesbeth Venema.
Two-Dimensional Magnetotransport in the Extreme Quantum Limit
A quantized Hall plateau of ρxy=3he2, accompanied by a minimum in ρxx, was observed at T<5 K in magnetotransport of high-mobility, two-dimensional electrons, when the lowest-energy, spin-polarized
Observation of a quarter of an electron charge at the ν = 5/2 quantum Hall state
Data is reported on shot noise generated by partitioning edge currents in the ν = 5/2 state, consistent with the charge of the quasiparticle being e/4, and inconsistent with other possible values, such as e/2 and e.
Fault tolerant quantum computation by anyons
A two-dimensional quantum system with anyonic excitations can be considered as a quantum computer. Unitary transformations can be performed by moving the excitations around each other. Measurements
Observation of an even-denominator quantum number in the fractional quantum Hall effect.
An even-denominator rational quantum number has been observed in the Hall resistance of a two-dimensional electron system and is absent in the lowest Landau level under comparable conditions.

The Fractional Quantum Hall states with non-Abelian statistics are studied and it is argued that the topological orders and the associated properties are robust against any kinds of small perturbations.
Direct observation of a fractional charge
Since Millikan's famous oil-drop experiments, it has been well known that electrical charge is quantized in units of the charge of an electron, e. For this reason, the theoretical prediction, by
Nonabelions in the fractional quantum Hall effect
Applications of conformal field theory to the theory of fractional quantum Hall systems are discussed. In particular, Laughlin's wave function and its cousins are interpreted as conformal blocks in
Observation of the e/3 Fractionally Charged Laughlin Quasiparticle
The existence of fractional charges carrying current is experimentally demonstrated. Using a 2D electron system in a high perpendicular magnetic field we measure the shot noise associated with
