New paper on the arxiv: Quantum spatial search with multiple excitations arxiv.org/abs/2410.05945 – an extension of the spatial search problem, where we mark k spins and find them simultaneously by searching in the k-excitation subspace.

Excited to present new work with @RoelandWiersema, @carrasqu, and Sougato Bose, where we propose a new algorithm for designing quantum gates! arxiv.org/abs/2401.05973 🧵 (1/7)

The primitive gates of quantum computing platforms usually involve only one or two qubits and simple Hamiltonians. But the Hamiltonian interactions that are physically possible can involve more qubits and combinations of Hamiltonian terms. (2/7)

In our new paper, we look at some limitations for quantum algorithms to solve nonlinear systems: arxiv.org/abs/2307.09593

Limitations for Quantum Algorithms to Solve Turbulent and Chaotic Systems

We investigate the limitations of quantum computers for solving nonlinear dynamical systems. In particular, we tighten the worst-case bounds of the quantum Carleman linearisation (QCL) algorithm...
