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…
A direct controlled-phase gate between microwave photons
Adrian Copetudo, Amon M. Kasper, Tanjung Krisnanda +4
The rich dynamics and large Hilbert space of quantum harmonic oscillators make them natural candidates for hardware-efficient and error-correctable quantum information processing.…
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…
