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…
Automatic tuning of a donor in a silicon quantum device using machine learning
Brandon Severin, Tim Botzem, Federico Fedele +12
Donor spin qubits in silicon offer one- and two-qubit gates with fidelities beyond 99%, coherence times exceeding 30 seconds, and compatibility with industrial manufacturing method…
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…
