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…
Superconducting Proximity Effect in Two-Dimensional Hole Gases
Serafim S. Babkin, Benjamin Joecker, Karsten Flensberg +2
Technology involving hybrid superconductor-semiconductor materials is a promising avenue for engineering quantum devices for information storage, manipulation, and transmission. Pr…
Error channels in quantum nondemolition measurements on spin systems
Benjamin Joecker, Holly G. Stemp, Irene Fernández de Fuentes +2
Quantum nondemolition (QND) measurements are a precious resource for quantum information processing. Repetitive QND measurements can boost the fidelity of qubit preparation and mea…
An electrically-driven single-atom `flip-flop' qubit
Rostyslav Savytskyy, Tim Botzem, Irene Fernandez de Fuentes +9
The spins of atoms and atom-like systems are among the most coherent objects in which to store quantum information. However, the need to address them using oscillating magnetic fie…
Engineering local strain for single-atom nuclear acoustic resonance in silicon
Laura A. O'Neill, Benjamin Joecker, Andrew D. Baczewski +1
Mechanical strain plays a key role in the physics and operation of nanoscale semiconductor systems, including quantum dots and single-dopant devices. Here we describe the design of…
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…
Full configuration interaction simulations of exchange-coupled donors in silicon using multi-valley effective mass theory
Benjamin Joecker, Andrew D. Baczewski, John K. Gamble +3
Donor spin in silicon have achieved record values of coherence times and single-qubit gate fidelities. The next stage of development involves demonstrating high-fidelity two-qubit…
Coherent electrical control of a single high-spin nucleus in silicon
Serwan Asaad, Vincent Mourik, Benjamin Joecker +12
Nuclear spins are highly coherent quantum objects. In large ensembles, their control and detection via magnetic resonance is widely exploited, e.g. in chemistry, medicine, material…
Transfer of a quantum state from a photonic qubit to a gate-defined quantum dot
Benjamin Joecker, Pascal Cerfontaine, Federica Haupt +3
Interconnecting well-functioning, scalable stationary qubits and photonic qubits could substantially advance quantum communication applications and serve to link future quantum pro…
Electron spin relaxation of single phosphorus donors in metal-oxide-semiconductor nanoscale devices
Stefanie B. Tenberg, Serwan Asaad, Mateusz T. Mądzik +12
We analyze the electron spin relaxation rate of individual ion-implanted P donors, in a large set of metal-oxide-semiconductor (MOS) silicon nanoscale devices, with…
