Certifying the quantumness of a nuclear spin qudit through its uniform precession

Autor: Vaartjes, Arjen, Nurizzo, Martin, Zaw, Lin Htoo, Wilhelm, Benjamin, Yu, Xi, Holmes, Danielle, Schwienbacher, Daniel, Kringhøj, Anders, van Blankenstein, Mark R., Jakob, Alexander M., Hudson, Fay E., Itoh, Kohei M., Murray, Riley J., Blume-Kohout, Robin, Anand, Namit, Dzurak, Andrew S., Jamieson, David N., Scarani, Valerio, Morello, Andrea

Spin precession is a textbook example of dynamics of a quantum system that exactly mimics its classical counterpart. Here we challenge this view by certifying the quantumness of exotic states of a nuclear spin through its uniform precession. The key

Creation and manipulation of Schr\'odinger cat states of a nuclear spin qudit in silicon

Autor: Yu, Xi, Wilhelm, Benjamin, Holmes, Danielle, Vaartjes, Arjen, Schwienbacher, Daniel, Nurizzo, Martin, Kringhøj, Anders, van Blankenstein, Mark R., Jakob, Alexander M., Gupta, Pragati, Hudson, Fay E., Itoh, Kohei M., Murray, Riley J., Blume-Kohout, Robin, Ladd, Thaddeus D., Dzurak, Andrew S., Sanders, Barry C., Jamieson, David N., Morello, Andrea

High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, for instance in continuous-variable states of oscillators such as microwave cavities or the moti

Scalable Atomic Arrays for Spin-Based Quantum Computers in Silicon

Autor: Jakob, Alexander M., Robson, Simon G., Firgau, Hannes R., Mourik, Vincent, Schmitt, Vivien, Holmes, Danielle, Posselt, Matthias, Mayes, Edwin L. H., Spemann, Daniel, Morello, Andrea, Jamieson, David N.

Semiconductor spin qubits combine excellent quantum performance with the prospect of manufacturing quantum devices using industry-standard metal-oxide-semiconductor (MOS) processes. This applies also to ion-implanted donor spins, which further afford

Improved placement precision of implanted donor spin qubits in silicon using molecule ions

Autor: Holmes, Danielle, Wilhelm, Benjamin, Jakob, Alexander M., Yu, Xi, Hudson, Fay E., Itoh, Kohei M., Dzurak, Andrew S., Jamieson, David N., Morello, Andrea

Donor spins in silicon-28 ($^{28}$Si) are among the most performant qubits in the solid state, offering record coherence times and gate fidelities above 99%. Donor spin qubits can be fabricated using the semiconductor-industry compatible method of de
