Fast universal quantum gate above the fault-tolerance threshold in silicon

Nature, 2021
Fault-tolerant quantum computers that can solve hard problems rely on quantum error correction1. One of the most promising error correction codes is the surface code2, which requires universal gate fidelities exceeding an error correction threshold of 99

Quantum gates and degenerations

Journal of Physics A: Mathematical and General, 2004
Summary: A three state Hamiltonian with a degenerate ground state is shown to exhibit the property of generating quantum gates for fixed values of the energy parameters just by using the ability of this quantum system to evolve in time yielding suitable sets of quantum probabilities.

A photon–photon quantum gate based on Rydberg interactions

Nature Physics, 2018
The interaction between Rydberg states of neutral atoms is strong and long-range, making it appealing to put it to use in the context of quantum technologies.

A photon–photon quantum gate based on a single atom in an optical resonator

Nature, 2016
That two photons pass each other undisturbed in free space is ideal for the faithful transmission of information, but prohibits an interaction between the photons.
