Towards Scaling Quantum Fine-Tuning of Foundational Time Series Models for Classification

Sang Hyub Kim, Julien Baglio, Rajiv Krishnakumar +7

Time-series foundation models produce rich embeddings, but whether quantum models can exploit them, and how far hybrid classical-quantum architectures scale, remains unclear. We ad…

Comment on 'Supervised quantum machine learning models are kernel methods'

Rajiv Krishnakumar

We identify a few small errors in the proof of Theorem 1 in M. Schuld, 'Supervised quantum machine learning models are kernel methods' (arXiv:2101.11020v2), Appendix A. These do no…

A Q# Implementation of a Quantum Lookup Table for Quantum Arithmetic Functions

Rajiv Krishnakumar, Mathias Soeken, Martin Roetteler +1

In this paper, we present Q# implementations for arbitrary single-variabled fixed-point arithmetic operations for a gate-based quantum computer based on lookup tables (LUTs). In ge…

A Threshold for Quantum Advantage in Derivative Pricing

Shouvanik Chakrabarti, Rajiv Krishnakumar, Guglielmo Mazzola +3

We give an upper bound on the resources required for valuable quantum advantage in pricing derivatives. To do so, we give the first complete resource estimates for useful quantum d…

Retrieval of cavity-generated atomic spin-squeezing after free-space release

Yunfan Wu, Rajiv Krishnakumar, Julián Martínez-Rincón +3

The compatibility of cavity-generated spin-squeezed atomic states with atom-interferometric sensors that require freely falling atoms is demonstrated. An ensemble of spin…
