Efficient Block Encoding of Structured Hamiltonians by Separating Where and What
Alessandro Summer, François Jamet
In fault-tolerant block encodings of structured Hamiltonians, the support geometry can set how the non-Clifford cost of SELECT scales with the system size, however many operators a…
Mpemba Effects in Quantum Complexity
Sreemayee Aditya, Alessandro Summer, Piotr Sierant +1
The Mpemba effect is the phenomenon whereby systems farther from equilibrium may relax faster. In this work, we show that this counterintuitive behavior appears in the very measure…
A resource theoretical unification of Mpemba effects: classical and quantum
Alessandro Summer, Mattia Moroder, Laetitia P. Bettmann +3
The Mpemba effect originally referred to the observation that, under certain thermalizing dynamics, initially hotter samples can cool faster than colder ones. This effect has since…
Anomalous transport in U(1)-symmetric quantum circuits
Alessandro Summer, Alex Nico-Katz, Shane Dooley +1
In this work we investigate discrete-time transport in a generic U(1)-symmetric disordered model tuned across an array of different dynamical regimes. We develop an aggregate quant…
A Review on Quantum Approximate Optimization Algorithm and its Variants
Kostas Blekos, Dean Brand, Andrea Ceschini +4
The Quantum Approximate Optimization Algorithm (QAOA) is a highly promising variational quantum algorithm that aims to solve combinatorial optimization problems that are classicall…
Calculating the many-body density of states on a digital quantum computer
Alessandro Summer, Cecilia Chiaracane, Mark T. Mitchison +1
Quantum statistical mechanics allows us to extract thermodynamic information from a microscopic description of a many-body system. A key step is the calculation of the density of s…
