Multipartite entanglement generation and contextuality tests using non-destructive three-qubit parity measurements
Suzanne B. van Dam, Julia Cramer, Tim H. Taminiau +1
We report on the realization and application of non-destructive three-qubit parity measurements on nuclear spin qubits in diamond. We use high-fidelity quantum logic to map the par…
One-second coherence for a single electron spin coupled to a multi-qubit nuclear-spin environment
Mohamed H. Abobeih, Julia Cramer, Michiel A. Bakker +4
Single electron spins coupled to multiple nuclear spins provide promising multi-qubit registers for quantum sensing and quantum networks. The obtainable level of control is determi…
Quantum Zeno subspaces by repeated multi-spin projections
Norbert Kalb, Julia Cramer, Matthew Markham +3
Repeated observations inhibit the coherent evolution of quantum states through the quantum Zeno effect. In multi-qubit systems this effect provides new opportunities to control com…
Repeated quantum error correction on a continuously encoded qubit by real-time feedback
Julia Cramer, Norbert Kalb, M. Adriaan Rol +6
Reliable quantum information processing in the face of errors is a major fundamental and technological challenge. Quantum error correction protects quantum states by encoding a log…
