When Wyner and Ziv Met Bayes in Quantum-Classical Realm

Mohammad Aamir Sohail, Touheed Anwar Atif, S. Sandeep Pradhan

In this work, we address the lossy quantum-classical source coding with the quantum side-information (QC-QSI) problem. The task is to compress the classical information about a qua…

Enhancing Quantum Expectation Values via Exponential Error Suppression and CVaR Optimization

Touheed Anwar Atif, Reuben Blake Tate, Stephan Eidenbenz

Precise quantum expectation values are crucial for quantum algorithm development, but noise in real-world systems can degrade these estimations. While quantum error correction is r…

Quantum soft-covering lemma with applications to rate-distortion coding, resolvability and identification via quantum channels

Touheed Anwar Atif, S. Sandeep Pradhan, Andreas Winter

We propose a quantum soft-covering problem for a given general quantum channel and one of its output states, which consists in finding the minimum rank of an input state needed to…

Lossy Quantum Source Coding with a Global Error Criterion based on a Posterior Reference Map

Touheed Anwar Atif, Mohammad Aamir Sohail, S. Sandeep Pradhan

We consider the lossy quantum source coding problem where the task is to compress a given quantum source below its von Neumann entropy. Inspired by the duality connections between…

Suppressing unwanted fluctuations in QAOA and approximate quantum annealing

Touheed Anwar Atif, Catherine Potts, David Haycraft +2

The quantum approximate optimisation algorithm (QAOA) was partially inspired by digitising quantum annealing. Based on this inspiration, we develop techniques to use the additional…
