Quadratic speedup for spatial search by continuous-time quantum walk

Simon Apers, Shantanav Chakraborty, Leonardo Novo +1

Continuous-time quantum walks provide a natural framework to tackle the fundamental problem of finding a node among a set of marked nodes in a graph, known as spatial search. Wheth…

Non-linear Boson Sampling

Nicolò Spagnolo, Daniel J. Brod, Ernesto F. Galvão +1

Boson Sampling is a task that is conjectured to be computationally hard for a classical computer, but which can be efficiently solved by linear-optical interferometers with Fock st…

A scheme for universal high-dimensional quantum computation with linear optics

Stefano Paesani, Jacob F. F. Bulmer, Alex E. Jones +2

Photons are natural carriers of high-dimensional quantum information, and, in principle, can benefit from higher quantum information capacity and noise-resilience. However, schemes…

Testing complementarity on a transmon quantum processor

Pedro M. Q. Cruz, J. Fernández-Rossier

We propose quantum circuits to test interferometric complementarity using symmetric two-way interferometers coupled to a which-path detector. First, we consider the two-qubit setup…

The polarizability of a confined atomic system: An application of Dalgarno-Lewis method

T. V. C. Antão, N. M. R. Peres

In this paper we give an application of Dalgarno-Lewis method, the latter not usually taught in quantum mechanics courses. This is very unfortunate since this method allows to bypa…

Witnesses of coherence and dimension from multiphoton indistinguishability tests

Taira Giordani, Chiara Esposito, Francesco Hoch +5

Quantum coherence marks a deviation from classical physics, and has been studied as a resource for metrology and quantum computation. Finding reliable and effective methods for ass…

Calculation of the ground-state Stark effect in small molecules using the variational quantum eigensolver

Carlos Tavares, Sofia Oliveira, Vitor Fernandes +2

As quantum computing approaches its first commercial implementations, quantum simulation emerges as a potentially ground-breaking technology for several domains, including Biology…

Closing Bell: Boxing black box simulations in the resource theory of contextuality

Rui Soares Barbosa, Martti Karvonen, Shane Mansfield

This chapter contains an exposition of the sheaf-theoretic framework for contextuality emphasising resource-theoretic aspects, as well as some original results on this topic. In pa…

Emergence of noncontextuality under quantum Darwinism

Roberto D. Baldijão, Rafael Wagner, Cristhiano Duarte +2

Quantum Darwinism proposes that the proliferation of redundant information plays a major role in the emergence of objectivity out of the quantum world. Is this kind of objectivity…

Gutzwiller wave function on a digital quantum computer

Bruno Murta, Joaquín Fernández-Rossier

The determination of the ground state of quantum many-body systems via digital quantum computers rests upon the initialization of a sufficiently educated guess. This requirement be…

Using a resource theoretic perspective to witness and engineer quantum generalized contextuality for prepare-and-measure scenarios

Rafael Wagner, Roberto D. Baldijão, Alisson Tezzin +1

We employ the resource theory of generalized contextuality as a tool for analyzing the structure of prepare-and-measure scenarios. We argue that this framework simplifies proofs of…
