Designing High-Fidelity Single-Shot Three-Qubit Gates: A Machine Learning Approach [PDF]
, 2016 Three-qubit quantum gates are key ingredients for quantum error correction and quantum information processing. We generate quantum-control procedures to design three types of three-qubit gates, namely Toffoli, Controlled-Not-Not and Fredkin gates.

Efficient Quantum Computation with Probabilistic Quantum Gates [PDF]
Physical Review Letters, 2005 With a combination of the quantum repeater and the cluster state approaches, we show that efficient quantum computation can be constructed even if all the entangling quantum gates only succeed with an arbitrarily small probability $p$. The required computational overhead scales efficiently both with $1/p$ and $n$, where $n$ is the number of qubits in ...

Quantum Gates to Other Universes [PDF]
Fortschritte der Physik, 2018 AbstractWe present a microscopic model of a bridge connecting two large Anti‐de‐Sitter Universes. The Universes admit a holographic description as three‐dimensional supersymmetric gauge theories based on large linear quivers, and the bridge is a small rank‐n gauge group that acts as a messenger.
