  Reliable manipulation of non-Abelian Ising anyons supported by Kitaev spin
liquids may enable intrinsically fault-tolerant quantum computation. Here, we
introduce a standalone scheme for both generating and detecting individual
Ising anyons using tunable gate voltages in a heterostructure containing a
non-Abelian Kitaev spin liquid and a monolayer semiconductor. The key
ingredients of our setup are a Kondo coupling to stabilize an Ising anyon in
the spin liquid around each electron in the semiconductor, and a large charging
energy to allow control over the electron numbers in distinct gate-defined
regions of the semiconductor. In particular, a single Ising anyon can be
generated at a disk-shaped region by gate tuning its electron number to one,
while it can be interferometrically detected by measuring the electrical
conductance of a ring-shaped region around it whose electron number is allowed
to fluctuate between zero and one. We provide concrete experimental guidelines
for implementing our proposal in promising candidate materials like
$\alpha$-RuCl$_3$.
