Practical implementation of Toffoli-based qubit rotation
Christoffer Hindlycke, Jakov Krnic, Jan-Åke Larsson
The Toffoli gate is an important universal quantum gate, and will alongside the Clifford gates be available in future fault-tolerant quantum computing hardware. Many quantum algori…

Phase Coordinate Uncomputation in Quantum Recursive Fourier Sampling
Christoffer Hindlycke, Niklas Johansson, Jan-Åke Larsson
Recursive Fourier Sampling (RFS) was one of the earliest problems to demonstrate a quantum advantage, and is known to lie outside the Merlin--Arthur complexity class. This work con…

Single-qubit rotation algorithm with logarithmic Toffoli count and gate depth
Christoffer Hindlycke, Jan-Åke Larsson
We propose a direct (non-recursive) algorithm for applying a rotation , -close to a desired rotation , to a single qubit using the Clifford+Toffoli gate set. Ou…
