Project description
Quantum interactive information processing: exploiting opportunities for efficiency
Quantum entanglement was first proposed by Albert Einstein and colleagues in 1935, followed soon after by Schrödinger’s infamous "cat" thought experiment and some quite extraordinary potential consequences. In 1972, scientists proved experimentally that two widely separated particles can be entangled. The era of quantum entanglement, responsible for most of the advantages of quantum computing over classical computing, is upon us. It garnered the 2022 Nobel Prize in physics and is paving the way for quantum hardware that can meet the requirements of theoretical quantum protocols. Funded by the European Research Council, the QInteract project will develop new tools and algorithms enabling elusive quantum advantages to be detected and realised efficiently.
Objective
We are approaching an era where the capabilities of quantum hardware begin to meet the requirements of theoretical quantum protocols. Such times give new urgency to the Central Challenge of the theory of quantum information processing:
For which tasks do quantum devices hold an advantage over their conventional counterparts?
My proposal addresses this challenge in the context of information processing with interacting parties, which is the natural setting for problems in cryptography, communication, and distributed computing. We take a two-pronged approach with each prong addressing an essential facet of interactive information processing while sharing a common focus on efficiency. A desired impact is to kick-start a new pragmatic trend that focuses on efficiency in areas where the main goal so far has been an information-theoretic understanding of ultimate quantum capabilities.
The first work package deals with the uniquely quantum resource of entanglement which is responsible for most quantum advantages in multi-party settings. We will propose new tools (e.g. entanglement-preserving reductions) that will allow us to systematically identify scenarios where the generally elusive quantum advantages can be detected and realized efficiently. We will also address major outstanding challenges like the Parallel Repetition question and finding a simple task capable of distinguishing two competing models of entanglement. The latter is our most ambitious goal which would provide an alternative proof for Connes' Embedding Problem and lay theory groundwork for an experiment capable of identifying the right mathematical description of reality.
The second work package will leverage Schur-Weyl duality to devise efficient algorithms for symmetric problems with quantum input. We will put forth new error reduction algorithms for black-box devices (e.g. quantum majority vote) and propose highly efficient explicit quantum circuits for key subroutines like quantum Schur sampling.
