Towards fault-tolerance with universal phase-error-transparent gates for high-spin cat codes
Kelvin Onggadinata, Si Yan Koh, Arghya Maity +5
High-dimensional nuclear spins offer a hardware-efficient route to quantum error correction (QEC), with the spin cat code providing intrinsic robustness against phase errors -- the…
Simultaneous High-Fidelity Readout and Strong Coupling for a Donor-Based Spin Qubit
Si Yan Koh, Weifan Wu, Kelvin Onggadinata +7
Superconducting resonators coupled to solid-state qubits offer a scalable architecture for long-range entangling operations and fast, high-fidelity readout. Realizing this requires…
Do single-shot projective readouts necessarily estimate the lifetime ?
Aparajita Modak, Sundeep Kapila, Bent Weber +3
When single-shot qubit readout protocols are adapted for multilevel systems, theoretical lifetime calculations often fall short of capturing the experimental lifetime trends.…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Orbitally resolved single-photon emission from an individual atomic vacancy center in a semiconductor
Gagandeep Singh, Xiaodan Lyu, Bi Qi Chong +11
Atomically confined spins are emerging as active components in quantum optoelectronic devices such as quantum bits and sensors. However, interrogating single spins at atomic length…
High-fidelity regimes of resonator-mediated controlled-Z gates between quantum-dot qubits
Guangzhao Yang, Marek Gluza, Si Yan Koh +6
Semiconductor double quantum dot (DQD) qubits coupled via superconducting microwave resonators provide a powerful means of long-range manipulation of the qubits' spin and charge de…
