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…

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…

Schrödinger cat states of a nuclear spin qudit in silicon

Xi Yu, Benjamin Wilhelm, Danielle Holmes +17

High-dimensional quantum systems are a valuable resource for quantum information processing. They can be used to encode error-correctable logical qubits, which has been demonstrate…

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

Danielle Holmes, Benjamin Wilhelm, Alexander M. Jakob +6

Donor spins in silicon-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…

Robust Macroscopic Schrödinger's Cat on a Nucleus

Pragati Gupta, Arjen Vaartjes, Xi Yu +2

We propose a scheme to generate spin cat states, i.e., superpositions of maximally separated quasiclassical states on a single high-dimensional nuclear spin in a solid-state device…
