Controllable interaction between photons and distant spins via vacuum Rabi oscillations
Xiao Xue, Jurgen Dijkema, Tobias Bonsen +7
Vacuum Rabi oscillations between a single photon and a single spin demonstrate the capability of harnessing light-matter interaction at the level of a single quantum of energy. Sin…
Persistence of Entangled States and High Fidelity Quantum Gate Operations in Si/SiGe Spin Qubits at High Temperature
S. Amitonov, A. AprÃ, M. Asker +20
We characterize single- and two-qubit operations in a SiGe quantum dot array, from the perspective of its quantum information processing capabilities. The analysis includes rigorou…
Distributing entanglement between distant semiconductor qubit registers using a shared-control shuttling link
Zarije Ademi, Marion Bassi, Cécile X. Yu +8
Semiconductor quantum processors have potential to scale to modular quantum computers, in which qubit registers are coupled by quantum links, enabling high connectivity and space f…
Mitigation of exchange cross-talk in dense quantum dot arrays
Daniel Jirovec, Pablo Cova Fariña, Stefano Reale +7
Coupled spins in semiconductor quantum dots are a versatile platform for quantum computing and simulations of complex many-body phenomena. However, on the path of scale-up, cross-t…
Operating semiconductor qubits without individual barrier gates
A. S. Ivlev, D. R. Crielaard, M. Meyer +8
Semiconductor spin qubits have emerged as a promising platform for quantum computing, following a significant improvement in their control fidelities over recent years. Increasing…
High-fidelity single-spin shuttling in silicon
Maxim De Smet, Yuta Matsumoto, Anne-Marije J. Zwerver +12
The computational power and fault-tolerance of future large-scale quantum processors derive in large part from the connectivity between the qubits. One approach to increase connect…
