Microwave dielectric properties of LiNbO and AlN at millikelvin temperatures and single-photon power
Alessandro Reineri, Francesco Crisa, Akshay Murthy +8
Efficient bidirectional microwave-optical photon conversion is a key capability for scaling superconducting quantum processors into distributed networks. However, achieving the nec…
Architectural scaling tradeoffs in modular 3D bosonic quantum processors
Shaojiang Zhu, Ugur Alyanak, Tanay Roy +7
We propose a modular three-dimensional bosonic quantum processor built from repeatable coupled-cavity modules linked by configurable interconnect networks. Using hardware-motivated…
Two-Level System Spectroscopy from Correlated Multilevel Relaxation in Superconducting Qubits
Tanay Roy, Xinyuan You, David van Zanten +5
Transmon qubits are a cornerstone of modern superconducting quantum computing platforms. Temporal fluctuations of energy relaxation in these qubits are widely attributed to microsc…
Oxygen distribution and segregation at grain boundaries in Nb and Ta-encapsulated Nb thin films for superconducting qubits
Jaeyel Lee, Dieter Isheim, Zuhawn Sung +14
We report on atomic-scale analyses of oxygen distribution and segregation at grain boundaries (GBs) of Nb and Ta-encapsulated Nb (Ta/Nb) thin films for superconducting qubits using…
Two-tooth bosonic quantum comb for temporal-correlation sensing
Shaojiang Zhu, Xinyuan You, Alexander Romanenko +1
We characterize the causal structure of coherence transport in open bosonic systems using a two-tooth quantum comb. We show that, by mapping sequential interactions between a struc…
