Controllable interaction between photons and distant spins via vacuum Rabi oscillations
Xiao Xue, Jurgen Dijkema, Tobias Bonsen +7
Vacuum Rabi oscillations between a single photon and a single spin demonstrate the capability of harnessing light-matter interaction at the level of a single quantum of energy. Sin…
Two-qubit logic between distant spins in silicon
Jurgen Dijkema, Xiao Xue, Patrick Harvey-Collard +6
Direct interactions between quantum particles naturally fall off with distance. For future-proof qubit architectures, however, it is important to avail of interaction mechanisms on…
Capacitive crosstalk in gate-based dispersive sensing of spin qubits
Eoin G. Kelly, Alexei Orekhov, Nico Hendrickx +8
In gate-based dispersive sensing, the response of a resonator attached to a quantum dot gate is detected by a reflected radio-frequency signal. This enables fast readout of spin qu…
Probing the Jaynes-Cummings Ladder with Spin Circuit Quantum Electrodynamics
Tobias Bonsen, Patrick Harvey-Collard, Maximilian Russ +4
We report observations of transitions between excited states in the Jaynes-Cummings ladder of circuit quantum electrodynamics with electron spins (spin circuit QED). We show that u…
Coherent spin-spin coupling mediated by virtual microwave photons
Patrick Harvey-Collard, Jurgen Dijkema, Guoji Zheng +3
We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a supercond…
On-chip microwave filters for high-impedance resonators with gate-defined quantum dots
Patrick Harvey-Collard, Guoji Zheng, Jurgen Dijkema +4
Circuit quantum electrodynamics (QED) employs superconducting microwave resonators as quantum buses. In circuit QED with semiconductor quantum-dot-based qubits, increasing the reso…

Quasi-periodic oscillations (QPO) originating from innermost regions of blazars can provide unique perspective of some of the burning issues in blazar studies including disk-jet co…
All-electrical universal control of a double quantum dot qubit in silicon MOS
Patrick Harvey-Collard, Ryan M. Jock, N. Tobias Jacobson +12
Qubits based on transistor-like Si MOS nanodevices are promising for quantum computing. In this work, we demonstrate a double quantum dot spin qubit that is all-electrically contro…

Si-MOS based QD qubits are attractive due to their similarity to the current semiconductor industry. We introduce a highly tunable MOS foundry compatible qubit design that couples…
High-fidelity single-shot readout for a spin qubit via an enhanced latching mechanism
Patrick Harvey-Collard, Benjamin D'Anjou, Martin Rudolph +9
The readout of semiconductor spin qubits based on spin blockade is fast but suffers from a small charge signal. Previous work suggested large benefits from additional charge mappin…
Valley splitting of single-electron Si MOS quantum dots
John King Gamble, Patrick Harvey-Collard, N. Tobias Jacobson +10
Silicon-based metal-oxide-semiconductor quantum dots are prominent candidates for high-fidelity, manufacturable qubits. Due to silicon's band structure, additional low-energy state…
Coherent coupling between a quantum dot and a donor in silicon
Patrick Harvey-Collard, N. Tobias Jacobson, Martin Rudolph +8
Individual donors in silicon chips are used as quantum bits with extremely low error rates. However, physical realizations have been limited to one donor because their atomic size…
