Superconducting Parallel-Plate Resonators for the Detection of Single Electron Spins
André Pscherer, Jannes Liersch, Patrick Abgrall +7
We introduce a multilayer superconducting microwave resonator with sub-Ohm impedance optimized for high coupling strength to single electron spins. The design minimizes the magneti…
Individual solid-state nuclear spin qubits with coherence exceeding seconds
James O'Sullivan, Jaime Travesedo, Louis Pallegoix +14
The ability to coherently control and read out qubits with long coherence times in a scalable system is a crucial requirement for any quantum processor. Nuclear spins in the solid…
All-microwave spectroscopy and polarization of individual nuclear spins in a solid
J. Travesedo, J. O'Sullivan, L. Pallegoix +10
We report magnetic resonance spectroscopy measurements of individual nuclear spins in a crystal coupled to a neighbouring paramagnetic center, detected using microwave fluorescence…
Deterministic generation of a 20-qubit two-dimensional photonic cluster state
James O'Sullivan, Kevin Reuer, Aleksandr Grigorev +11
Multidimensional cluster states are a key resource for robust quantum communication, measurement-based quantum computing and quantum metrology. Here, we present a device capable of…
