Quantum Krylov Algorithm for Szegö Quadrature
William Kirby, Yizhi Shen, Daan Camps +3
We present a quantum algorithm to evaluate matrix elements of functions of unitary operators. The method is based on calculating quadrature nodes and weights using data collected f…
Efficient LCU block encodings through Dicke states preparation
Filippo Della Chiara, Martina Nibbi, Yizhi Shen +1
With the Quantum Singular Value Transformation (QSVT) emerging as a unifying framework for diverse quantum speedups, the efficient construction of block encodings -- their fundamen…
Efficient Quantum Implementation of Dynamical Mean Field Theory for Correlated Materials
Norman Hogan, Efekan Kökcü, Thomas Steckmann +6
The accurate theoretical description of materials with strongly correlated electrons is a formidable challenge in condensed matter physics and computational chemistry. Dynamical Me…
From noisy observables to accurate ground state energies: a quantum classical signal subspace approach with denoising
Hardeep Bassi, Yizhi Shen, Harish S. Bhat +1
We propose a hybrid quantum-classical algorithm for ground state energy (GSE) estimation that remains robust to highly noisy data and exhibits low sensitivity to hyperparameter tun…
QCLAB: A Matlab Toolbox for Quantum Computing
Sophia Keip, Daan Camps, Roel Van Beeumen
We introduce QCLAB, an object-oriented MATLAB toolbox for constructing, representing, and simulating quantum circuits. Designed with an emphasis on numerical stability, efficiency,…
EHands: Quantum Protocol for Polynomial Computation on Real-Valued Encoded States
Jan Balewski, C. Pestano, Mercy G. Amankwah +3
We present EHands, a quantum-native protocol for implementing multivariable polynomial transformations on quantum processors. The protocol introduces four fundamental, reversible o…
