Protocols of coherent motion control for an interaction-driven Rydberg gate
Valentin Magro, Wojciech Adamczyk, Sylvain de Léséleuc
Generating entanglement between two Rydberg atoms is at the core of neutral-atom quantum computers. Current two-qubit gates operate in the Rydberg-blockade regime, in which the ful…
Fundamentals of Trapped Ions and Quantum Simulation of Chemical Dynamics
Guido Pagano, Wojciech Adamczyk, Visal So
Trapped atomic ions are among the most advanced platforms for quantum simulation, computation, and metrology, offering long coherence times and precise, individual control over bot…
Rapid high-temperature initialisation and readout of spins in silicon with 10 THz photons
Aidan G. McConnell, Nils Dessmann, Wojciech Adamczyk +6
Each cycle of a quantum computation requires a quantum state initialisation. For semiconductor-based quantum platforms, initialisation is typically performed via slow microwave pro…
Non-linear cooling and control of a mechanical quantum harmonic oscillator
Matteo Simoni, Ivan Rojkov, Matteo Mazzanti +7
Non-linearities are a key feature allowing non-classical control of quantum harmonic oscillators. However, when non-linearities are strong, designing protocols for control is often…
Two-photon cooling of calcium atoms
Wojciech Adamczyk, Silvan Koch, Claudia Politi +6
We demonstrate sub-Doppler cooling of calcium atoms using a two-photon transition from the ground state to the upper state via the intermediate s…
