Properly proved. Has structure, has flavour, has a point.
Summary
Researchers at ETH Zurich have developed a new method for creating stable quantum logical operations using neutral atom qubits. The quantum gates are based on geometric phases, making them extremely robust against experimental noise. This approach offers advantages over superconducting circuits and trapped ions, as neutral atoms are less sensitive to disturbances and can be scaled to thousands of qubits more easily.

· 5 pulledQuantum bits, or qubits, which are required for building quantum computers, come in different kinds.
Neutral atoms trapped with laser light also have a lot going for them: since they carry no electric charge, they are less sensitive to disturbances.
Trapping with laser light makes it easy to realize several thousand qubits in a single system – using superconductors or ions this is much more difficult.
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms.
Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.
