Dynamical Decoupling of Nonclassical States in a Biased-Noise Spin Qudit
Arjen Vaartjes, Namit Anand, Rocky Y. Su +16
Encoding quantum information in -dimensional systems (qudits) with offers appealing new directions for resource-efficient quantum computing. However, protecting the cohere…
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…

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…
A silicon spin vacuum: isotopically enriched silicon-on-insulator and silicon from ultra-high fluence ion implantation
Shao Qi Lim, Brett C. Johnson, Sergey Rubanov +7
Isotopically enriched silicon (Si) can greatly enhance qubit coherence times by minimizing naturally occurring Si which has a non-zero nuclear spin. Ultra-high fluence $^{28…
Strong coupling of a superconducting flux qubit to single bismuth donors
T. Chang, I. Holzman, S. Q. Lim +4
The realization of a quantum computer represents a tremendous scientific and technological challenge due to the extreme fragility of quantum information. The physical support of in…
Certifying the quantumness of a nuclear spin qudit through its uniform precession
Arjen Vaartjes, Martin Nurizzo, Lin Htoo Zaw +16
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 ex…
