Multi-Boundary Many-Body Quantum Teleportation
Tal Schwartzman, Antonio F. Rotundo, Raz Monsonego +1
Unlike standard quantum teleportation, many-body teleportation uses scrambling to transmit quantum information. In this protocol, initially localized information spreads over many…
Approximate Sparse State Preparation with the Grover-Rudolph Algorithm
Debora Ramacciotti, Martin Steinbach, Bence Temesi +2
Sparse quantum state preparation is a common subroutine in quantum algorithms, where classical data with few nonzero entries must be loaded into a quantum state. In this work, we c…
Beyond asymptotic scaling: Comparing functional quantum linear solvers
Andreea-Iulia Lefterovici, Michael Perk, Debora Ramacciotti +3
Solving systems of linear equations is a key subroutine in many quantum algorithms. In the last 15 years, many quantum linear solvers (QLS) have been developed, competing to achiev…
Effective dynamics from minimising dissipation
Antonio F. Rotundo, Paolo Perinotti, Alessandro Bisio
It is known that the same physical system can be described by different effective theories depending on the scale at which it is observed. In this work, we formulate a prescription…
Realistic Runtime Analysis for Quantum Simplex Computation
Sabrina Ammann, Maximilian Hess, Debora Ramacciotti +10
In recent years, strong expectations have been raised for the possible power of quantum computing for solving difficult optimization problems, based on theoretical, asymptotic wors…
A simple quantum algorithm to efficiently prepare sparse states
Debora Ramacciotti, Andreea-Iulia Lefterovici, Antonio F. Rotundo
State preparation is a fundamental routine in quantum computation, for which many algorithms have been proposed. Among them, perhaps the simplest one is the Grover-Rudolph algorith…
An entropic uncertainty principle for mixed states
Antonio F. Rotundo, René Schwonnek
The entropic uncertainty principle in the form proven by Maassen and Uffink yields a fundamental inequality that is prominently used in many places all over the field of quantum in…
Wormholes from Averaging over States
Ben Freivogel, Dora Nikolakopoulou, Antonio F. Rotundo
An important question about black holes is to what extent a typical pure state differs from the ensemble average. We show that this question can be answered within semi-classical g…
