Interplay of Zeeman Splitting and Tunnel Coupling in Coherent Spin Qubit Shuttling
Ssu-Chih Lin, Paul Steinacker, MengKe Feng +11
Spin shuttling offers a promising approach for developing scalable silicon-based quantum processors by addressing the connectivity limitations of quantum dots. In this work, we dem…
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…
Maximizing the nondemolition nature of a quantum measurement via an adaptive readout protocol
Arjen Vaartjes, Rocky Yue Su, Laura A. O'Neill +15
Quantum error correction (QEC) requires non-invasive measurements for fault tolerant quantum computing. Deviations from ideal quantum non-demolition (QND) measurements can disturb…
Enhancement of Electric Drive in Silicon Quantum Dots with Electric Quadrupole Spin Resonance
Philip Y. Mai, Pedro H. Pereira, Lucas Andrade Alonso +19
Quantum computation with electron spin qubits requires coherent and efficient manipulation of these spins, typically accomplished through the application of alternating magnetic or…
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…
