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…
Characterizing Gaussian quantum processes with Gaussian resources
Logan W. Grove, Pratik J. Barge, Kevin Valson Jacob
Characterizing quantum processes is indispensable for the implementation of any task in quantum information processing. In this paper, we develop an efficient method to fully chara…
Reducing classical communication costs in multiplexed quantum repeaters using hardware-aware quasi-local policies
Stav Haldar, Pratik J. Barge, Xiang Cheng +5
Future quantum networks will have nodes equipped with multiple quantum memories, allowing for multiplexing and entanglement distillation strategies in order to increase fidelities…
Polarization-Entanglement Dynamics in Optical Fibers: Mitigating Decay in the Non-Markovian Regime with Dynamical Decoupling
Pratik J. Barge, Arshag Danageozian, Manish K. Gupta +2
Future distributed quantum systems and networks are likely to rely, at least in part, on the existing fiber infrastructure for entanglement distribution; hence, a precise understan…
