Electron readout contrast enhancement in the parallel nuclear regime of an exchange-coupled donor spin qubit system
Holly G. Stemp, Mark R. van Blankenstein, Benjamin Wilhelm +10
Recent experiments on donor-based spin qubits in silicon have leveraged the exchange interaction between electrons bound to separate donor nuclei to perform two-qubit operations. A…
Scalable entanglement of nuclear spins mediated by electron exchange
Holly G. Stemp, Mark R. van Blankenstein, Serwan Asaad +11
The use of nuclear spins for quantum computation is limited by the difficulty in creating genuine quantum entanglement between distant nuclei. Current demonstrations of nuclear ent…
Tomography of entangling two-qubit logic operations in exchange-coupled donor electron spin qubits
Holly G. Stemp, Serwan Asaad, Mark R. van Blankenstein +19
Scalable quantum processors require high-fidelity universal quantum logic operations in a manufacturable physical platform. Donors in silicon provide atomic size, excellent quantum…
Navigating the 16-dimensional Hilbert space of a high-spin donor qudit with electric and magnetic fields
Irene Fernández de Fuentes, Tim Botzem, Mark A. I. Johnson +11
Efficient scaling and flexible control are key aspects of useful quantum computing hardware. Spins in semiconductors combine quantum information processing with electrons, holes or…
Precision tomography of a three-qubit donor quantum processor in silicon
Mateusz T. Mądzik, Serwan Asaad, Akram Youssry +17
Nuclear spins were among the first physical platforms to be considered for quantum information processing, because of their exceptional quantum coherence and atomic-scale footprint…
Measuring out-of-time-ordered correlation functions without reversing time evolution
Philip Daniel Blocher, Serwan Asaad, Vincent Mourik +3
Out-of-time-ordered correlation functions (OTOCs) play a crucial role in the study of thermalization, entanglement, and quantum chaos, as they quantify the scrambling of quantum in…
Exploring quantum chaos with a single nuclear spin
Vincent Mourik, Serwan Asaad, Hannes Firgau +5
Most classical dynamical systems are chaotic. The trajectories of two identical systems prepared in infinitesimally different initial conditions diverge exponentially with time. Qu…
