Efficient -qubit entangling operations via a superconducting quantum router
Xuntao Wu, Haoxiong Yan, Gustav Andersson +13
Quantum algorithms on near-term quantum processors are typically executed using shallow quantum circuits composed of one- and two-qubit gates. However, as circuit depth and gate nu…
Loss Mechanisms in High-coherence Multimode Mechanical Resonators Coupled to Superconducting Circuits
Raquel Garcia Belles, Alexander Anferov, Lukas F. Deeg +14
Circuit quantum acoustodynamics (cQAD) devices have a wide range of applications in quantum science, all of which depend crucially on the quantum coherence of the mechanical subsys…
A Flux-Tunable cavity for Dark matter detection
Fang Zhao, Ziqian Li, Akash V. Dixit +7
Developing a dark matter detector with wide mass tunability is an immensely desirable property, yet it is challenging due to maintaining strong sensitivity. Resonant cavities for d…
Mitigating cosmic ray-like correlated events with a modular quantum processor
Xuntao Wu, Yash J. Joshi, Haoxiong Yan +14
Quantum processors based on superconducting qubits are being scaled to larger qubit numbers, enabling the implementation of small-scale quantum error correction codes. However, cat…
Niobium coaxial cavities with internal quality factors exceeding 1.5 billion for circuit quantum electrodynamics
Andrew E. Oriani, Fang Zhao, Tanay Roy +6
Group-V materials such as niobium and tantalum have become popular choices for extending the performance of circuit quantum electrodynamics (cQED) platforms allowing for quantum pr…
Millimeter-Wave Superconducting Qubit
Alexander Anferov, Fanghui Wan, Shannon P. Harvey +2
Manipulating the electromagnetic spectrum at the single-photon level is fundamental for quantum experiments. In the visible and infrared range, this can be accomplished with atomic…
