Resonant two-qubit gates for fermionic simulations with spin qubits
Konstantinos Tsoukalas, Alexei Orekhov, Bence Hetényi +15
In gate-defined semiconductor spin qubits, the highly tunable Heisenberg exchange interaction is leveraged to implement fermionic two-qubit gates such as CZ and SWAP. However, the…
A dressed singlet-triplet qubit in germanium
Konstantinos Tsoukalas, Uwe von Lüpke, Alexei Orekhov +15
In semiconductor hole spin qubits, low magnetic field () operation extends the coherence time () but proportionally reduces the gate speed. In contrast, singlet-…
Two-qubit spectroscopy of spatiotemporally correlated quantum noise in superconducting qubits
Uwe von Lüpke, Félix Beaudoin, Leigh M. Norris +9
Noise that exhibits significant temporal and spatial correlations across multiple qubits can be especially harmful to both fault-tolerant quantum computation and quantum-enhanced m…
An argon ion beam milling process for native layers enabling coherent superconducting contacts
Lukas Grünhaupt, Uwe von Lüpke, Daria Gusenkova +8
We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our…
