Precision Bounds on Continuous-Variable State Tomography Using Classical Shadows

March 18, 2024
Author(s)
Srilekha Gandhari, Victor Albert, Thomas Gerrits, Jacob Taylor, Michael Gullans
Shadow tomography is a framework for constructing succinct descriptions of quantum states, called classical shadows, with powerful methods to bound the estimators used. Classical shadows are well-studied in the discrete-variable case, which consists of sta

Craig R. Copeland, Adam L. Pintar, Ronald G. Dixson, Ashish Chanana, Kartik Srinivasan, Daron Westly, Robert Ilic, Marcelo Davanco, Samuel M. Stavis
In a popular integration process for quantum information technologies, localization microscopy of quantum emitters guides lithographic placement of photonic structures. However, a complex coupling of microscopy and lithography errors degrades registration

Rapid Automated Antenna Alignment on Robotic Antenna Ranges

March 17, 2024
Author(s)
Benjamin Moser, Joshua Gordon
We present methods to automate AUT-probe alignment on a robotic antenna range using iterative fitting methods. Data collected during pose refinement is used to characterize offsets to the robot motion frame and the end effector measurement frame with

National Institute on Drug Abuse Clinical Trials Network Meeting Report: Managing Patients Exposed to Xylazine-Adulterated Opioids in Emergency, Hospital and Addiction Care Settings
