- Abstract: One of the most promising nascent technologies, quantum computation faces a
major challenge: The need for stable computational building blocks. We present
the quantum-optical realization of non-adiabatic holonomies that can be used as
single-qubit quantum gates. The hallmark topological protection of non-Abelian
geometric phases reduces the need for quantum error correction on a fundamental
physical level, while the inherent non-adiabaticity of the structures paves the
way for unprecedented miniaturization. To demonstrate their versatility, we
realize the Hadamard and Pauli-X gates, experimentally show their non-Abelian
nature, and combine them into a single-qubit quantum algorithm, the PQ penny
flipover. The planar geometry of such designs enables them to be substituted
for the conventional directional coupler meshes currently in wide-spread use in
photonic quantum architectures across all platforms.

Quantum interference can be enabled by projecting the quantum state onto ambiguous properties that render the photons indistinguishable.
By combining these ideas, here we design and experimentally demonstrate a simple and robust scheme that tailors quantum interference to engineer photonic states.
We believe these spatially-engineered multi-photon quantum states may be of significance in fields such as quantum metrology, microscopy, and communications.
