Pulse-optimised circuit elements for scalable and noise-resilient quantum chemistry
Henrik Gothen, Christopher K. Long, Djamila Hiller +4
Useful chemistry calculations on near-term quantum processors are hindered by current algorithmic runtimes. We develop a methodology to significantly reduce these runtimes. Typical…
Concatenated continuous driving of silicon qubit by amplitude and phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +22
The rate of coherence loss is lower for a qubit under the Rabi drive than a freely evolving qubit . Building on this principle, concatenated continuous d…
Surface-Code Thresholds and Qubit Footprints in Shuttling-Based Spin-Qubit Railways
Arun John Moncy, Reza Dastbasteh, Josu Etxezarreta Martinez +5
We present a fault-tolerant mapping of rotated surface codes onto a silicon spin-qubit railway architecture, utilizing electron shuttling to resolve the wiring fan-out…
Valley enhanced Rabi frequency in n-type planar Silicon-MOS quantum dot
Xunyao Luo, Xander Peetroons, Tsung-Yeh Yang +27
Electron spin resonance spectroscopy (ESR) of a single electron in planar Si-MOS quantum dot is reported in the vicinity of a valley level anti-crossing. A number of one and two-ph…
Robust spin-qubit control in a natural Si-MOS quantum dot using phase modulation
Takuma Kuno, Takeru Utsugi, Andrew J. Ramsay +13
Silicon quantum dots are one of the most promising candidates for practical quantum computers because of their scalability and compatibility with the well-established complementary…
High Fidelity Qubit Control in a Natural Si-MOS Quantum Dot using a 300 mm Silicon on Insulator Wafer
Xander Peetroons, Xunyao Luo, Tsung-Yeh Yang +26
We demonstrate high-fidelity single qubit control in a natural Si-MOS quantum dot fabricated in an industrial 300 mm wafer process on a silicon on insulator (SOI) wafer using elect…
