Promise and Challenges of Distimation
Joshua Carlo A. Casapao, Ananda G. Maity, Naphan Benchasattabuse +4
Estimating the quality of raw entangled states and distilling high-fidelity entanglement traditionally require two separate link-layer protocols in a quantum network stack, each co…
Parameter Calibration for Reduced-Bandwidth Two-Photon Waveguide-QED Simulations
Romain Piron, Akihito Soeda
Waveguide-QED platforms represent one potential approach to scalable quantum technologies, but their simulation remains computationally demanding due to the large number of frequen…
Renormalization Treatment of IR and UV Cutoffs in Waveguide QED and Implications to Numerical Model Simulation
Romain Piron, Akihito Soeda
We present a non-perturbative, first-principles derivation of renormalization relations for waveguide-QED models, explicitly accounting for the infrared (IR) and ultraviolet (UV) c…
Efficient graph-diagonal characterization of noisy states distributed over quantum networks via Bell sampling
Zherui Jerry Wang, Joshua Carlo A. Casapao, Naphan Benchasattabuse +6
Graph states are an important class of entangled states that serve as a key resource for distributed information processing and communication in quantum networks. In this work, we…
Low Cost Bayesian Experimental Design for Quantum Frequency Estimation with Decoherence
Alexandra Ramôa, LuÃs Paulo Santos, Akihito Soeda
A two-level quantum system evolving under a time-independent Hamiltonian produces oscillatory measurement probabilities. The estimation of the associated frequency is a cornerstone…
A double selection entanglement distillation-based state estimator
Joshua Carlo A. Casapao, Ananda G. Maity, Naphan Benchasattabuse +4
With the advent of practical quantum communication networks drawing closer, there is a growing need for reliable estimation protocols that can efficiently characterize quantum reso…
