Measuring higher-order bulk topology in a programmable quantum simulator
Pratik Sathe, Niclas Heinsdorf, Majid Kheirkhah +13
Topological insulators lie outside the standard Landau paradigm: Instead of being characterized by local order parameters and spontaneous symmetry breaking, their defining properti…
Analog-Digital Quantum Computing with Quantum Annealing Processors
Rahul Deshpande, Majid Kheirkhah, Chris Rich +12
Quantum annealing processors typically control qubits in unison, attenuating quantum fluctuations uniformly until the applied system Hamiltonian is diagonal in the computational ba…
A Comprehensive Cross-Model Framework for Benchmarking the Performance of Quantum Hamiltonian Simulations
Avimita Chatterjee, Sonny Rappaport, Anish Giri +5
Quantum Hamiltonian simulation is one of the most promising applications of quantum computing and forms the basis for many quantum algorithms. Benchmarking them is an important gau…
Benchmarking the Operation of Quantum Heuristics and Ising Machines: Scoring Parameter Setting Strategies on Optimization Applications
David E. Bernal Neira, Robin Brown, Pratik Sathe +4
We discuss guidelines for evaluating the performance of parameterized stochastic solvers for optimization problems, with particular attention to systems that employ novel hardware,…
Universal localization-delocalization transition in chiral-symmetric Floquet drives
Adrian B. Culver, Pratik Sathe, Albert Brown +2
Periodically driven systems often exhibit behavior distinct from static systems. In single-particle, static systems, any amount of disorder generically localizes all eigenstates in…
Topological Triviality of Flat Hamiltonians
Pratik Sathe, Rahul Roy
Landau levels play a key role in theoretical models of the quantum Hall effect. Each Landau level is degenerate, flat and topologically non-trivial. Motivated by Landau levels, we…
Compact Wannier Functions in One Dimension
Pratik Sathe, Rahul Roy
Wannier functions have widespread utility in condensed matter physics and beyond. Topological physics, on the other hand, has largely involved the related notion of compactly-suppo…
Optimization Applications as Quantum Performance Benchmarks
Thomas Lubinski, Carleton Coffrin, Catherine McGeoch +3
Combinatorial optimization is anticipated to be one of the primary use cases for quantum computation in the coming years. The Quantum Approximate Optimization Algorithm (QAOA) and…
Scattering Expansion for Localization in One Dimension: from Disordered Wires to Quantum Walks
Adrian B. Culver, Pratik Sathe, Rahul Roy
We present a perturbative approach to disordered systems in one spatial dimension that accesses the full range of phase disorder and clarifies the connection between localization a…

Compactly Supported Wannier Functions and Strictly Local Projectors
Pratik Sathe, Fenner Harper, Rahul Roy
Wannier functions that are maximally localized help in understanding many properties of crystalline materials. In the absence of topological obstructions, they are at least exponen…
Search and rescue at sea aided by hidden flow structures
Mattia Serra, Pratik Sathe, Irina Rypina +6
Every year hundreds of people die at sea because of vessel and airplane accidents. A key challenge in reducing the number of these fatalities is to make Search and Rescue (SAR) alg…
Uncovering the Edge of the Polar Vortex
Mattia Serra, Pratik Sathe, Francisco Beron-Vera +1
The polar vortices play a crucial role in the formation of the ozone hole and can cause severe weather anomalies. Their boundaries, known as the vortex `edges', are typically ident…
