Adaptive thresholding for scalable measurement-based qubit reset
Qian Cao, Unnati Akhouri, Samuel Vizvary +3
Fast, high-fidelity qubit initialization is a key primitive for scalable quantum information processing, but conventional reset protocols either require long relaxation times or di…
Mixed-State Symmetry-Protected Topology and Strong-to-Weak Spontaneous Symmetry Breaking in a Superconducting Qubit Array
Qian Cao, Zhen Bi, Kater W. Murch
We experimentally investigate how symmetry-protected topological order in a one-dimensional cluster state is transformed by measurement and decoherence in a five-qubit superconduct…
Anomalous Microwave Response in YBCO Resonators beyond the Two-Level-System Model
Kaiwen Zheng, Nathan J. Johnson, Nathan T. Thobaben +5
We report the microwave response of coplanar-waveguide (CPW) resonators fabricated from (YBCO) thin films over temperatures from approximately $70~\math…
Temporal Diffraction Grating for Engineered Superconducting Qubit Dissipation
Pratik J. Barge, Kater W. Murch
Parametric frequency modulation is a standard tool in superconducting circuits for activating tunable interactions and implementing quantum gates. Here, we engineer dissipation in…
Measurement and Control of the Complex Berry Phase in a Quantum System
Pratik J. Barge, Qian Cao, Niklas Hörnedal +2
The Berry phase is a geometric phase acquired during adiabatic evolution over a closed loop in parameter space. It plays an essential role in geometric quantum gates and other phas…
Graduate Training in Quantum Information Science and Engineering: Lessons, Challenges, and a Roadmap from the NSF Research Traineeship Programs
Yohannes Abate, Victor Acosta, Alessandro Alabastri +31
Since 2019, eighteen NSF Research Traineeship (NRT) awards in quantum information science and engineering (QISE) and adjacent fields have been funded, constituting the largest NSF-…
Quantum metrology enhanced by effective time reversal
Yu-Xin Wang, Flavio Salvati, David R. M. Arvidsson-Shukur +3
Quantum metrology involves the application of quantum resources to enhance measurements. Several communities have developed quantum-metrology strategies that leverage effective tim…
Real-time Monitoring of Neon Film Growth for Electron-on-Neon Qubits
Sidharth Duthaluru, Kaiwen Zheng, Erik A. Henriksen +1
Electron-on-neon (eNe) charge states coupled to superconducting circuits are a promising platform for quantum computing. Control over the formation of these charge states requires…
Superconducting-antiqubit simulation enables optimal phase estimation via unitary inversion
Xingrui Song, Surihan Sean Borjigin, Flavio Salvati +4
A positron is equivalent to an electron traveling backward through time. Casting transmon superconducting qubits as akin to electrons, we simulate a positron with a transmon subjec…
Surface Morphology Assisted Trapping of Strongly Coupled Electron-on-Neon Charge States
Kaiwen Zheng, Xingrui Song, Kater W. Murch
Single electrons confined to a free neon surface and manipulated through the circuit quantum electrodynamics (circuit QED) architecture is a promising novel quantum computing platf…
Sub-micron Circuit Fabrication on Diamond Anvils for Mesoscopic High-Pressure Experiments
Z. R. Rehfuss, K. Zheng, S. L. Gould +2
We present a novel fabrication procedure to produce high-quality lift-off structures on diamond anvils extending from the culet down to the slanted facets. Feature sizes down to 50…
