Resource-efficient simulation of noisy quantum circuits and application to network-enabled QRAM optimization
Luís Bugalho, Emmanuel Zambrini Cruzeiro, Kevin C. Chen +3
Giovannetti, Lloyd, and Maccone [Phys. Rev. Lett. 100, 160501] proposed a quantum random access memory (QRAM) architecture to retrieve arbitrary superpositions of (quantum) mem…
Quantum dynamics for energetic advantage in a charge-based classical full-adder
João P. Moutinho, Marco Pezzutto, Sagar Pratapsi +5
We present a proposal for a one-bit full-adder to process classical information based on the quantum reversible dynamics of a triple quantum dot system. The device works via the re…
Quantum density peak clustering
Duarte Magano, Lorenzo Buffoni, Yasser Omar
Clustering algorithms are of fundamental importance when dealing with large unstructured datasets and discovering new patterns and correlations therein, with applications ranging f…
Propagating Quantum Microwaves: Towards Applications in Communication and Sensing
Mateo Casariego, Emmanuel Zambrini Cruzeiro, Stefano Gherardini +22
The field of propagating quantum microwaves has started to receive considerable attention in the past few years. Motivated at first by the lack of an efficient microwave-to-optical…
Open-Air Microwave Entanglement Distribution for Quantum Teleportation
Tasio Gonzalez-Raya, Mateo Casariego, Florian Fesquet +7
Microwave technology plays a central role in current wireless communications, standing among them mobile communication and local area networks (LANs). The microwave range shows rel…
Third law of thermodynamics and the scaling of quantum computers
Lorenzo Buffoni, Stefano Gherardini, Emmanuel Zambrini Cruzeiro +1
The third law of thermodynamics, also known as the Nernst unattainability principle, puts a fundamental bound on how close a system, whether classical or quantum, can be cooled to…
Comment on "Scrutinizing pion-pion scattering in light of recent lattice phase shifts"
Eef van Beveren, George Rupp
In a recent paper by Xiu-Li Gao, Zhi-Hui Guo, Zhiguang Xiao, and Zhi-Yong Zhou, Phys. Rev. D 105, 094002 (2022), here referred to as I, -wave scattering phase shifts obtain…
Distributing Multipartite Entanglement over Noisy Quantum Networks
Luís Bugalho, Bruno C. Coutinho, Francisco A. Monteiro +1
A quantum internet aims at harnessing networked quantum technologies, namely by distributing bipartite entanglement between distant nodes. However, multipartite entanglement betwee…
Adiabatic Quantum Algorithm for Multijet Clustering in High Energy Physics
Diogo Pires, Yasser Omar, João Seixas
The currently predicted increase in computational demand for the upcoming High-Luminosity Large Hadron Collider (HL-LHC) event reconstruction, and in particular jet clustering, is…
Understanding the and masses as well as their widths
Eef van Beveren, George Rupp
The low and approximately equal masses of the scalar mesons and , as well as their relatively small decay widths, are impossible to understand in terms of stan…
Modern meson spectroscopy: the fundamental role of unitarity
Eef van Beveren, George Rupp
The importance of -matrix unitarity in realistic meson spectroscopy is reviewed, both its historical development and more recent applications. First the effects of imposing -…
Bi-frequency illumination: a quantum-enhanced protocol
Mateo Casariego, Yasser Omar, Mikel Sanz
Quantum-enhanced, idler-free sensing protocol to measure the response of a target object to the frequency of a probe in a noisy and lossy scenario is proposed. In this protocol, a…
Twisted bilayer graphene: low-energy physics, electronic and optical properties
G. Catarina, B. Amorim, Eduardo V. Castro +2
Van der Waals (vdW) heterostructures ---formed by stacking or growing two-dimensional (2D) crystals on top of each other--- have emerged as a new promising route to tailor and engi…
Heavy quarkonia: the beauty and the beasts
George Rupp, Eef van Beveren
New enhancements in the charmonium and bottomonium spectra observed since 2003 are very briefly reviewed. Special attention is paid to (formerly ) owing to…
Colour field densities of the quark-antiquark excited flux tubes in SU(3) lattice QCD
P. Bicudo, N. Cardoso, M. Cardoso
We combine techniques previously utilised to study flux tube field density profiles and to study the excited spectrum of the gluonic fields produced by a static quark-antiquark pai…
Perceptrons from Memristors
Francisco Silva, Mikel Sanz, João Seixas +2
Memristors, resistors with memory whose outputs depend on the history of their inputs, have been used with success in neuromorphic architectures, particularly as synapses and non-v…
A Fixed-Target Programme at the LHC: Physics Case and Projected Performances for Heavy-Ion, Hadron, Spin and Astroparticle Studies
C. Hadjidakis, D. Kikoła, J. P. Lansberg +29
We review the context, the motivations and the expected performances of a comprehensive and ambitious fixed-target program using the multi-TeV proton and ion LHC beams. We also pro…
Spontaneous generation of phononic entanglement in quantum dark-soliton qubits
Muzzamal I. Shaukat, Eduardo. V. Castro, Hugo Terças
We show that entanglement between two solitary qubits in quasi-one-dimensional Bose-Einstein condensates can be spontaneously generated due to quantum fluctuations. Recently we hav…
Quantum dark soliton (qubits) in Bose Einstein condensates
Muzzamal I. Shaukat, Eduardo V. Castro, Hugo Terças
We study the possibility of using dark soliton in quasi one dimensional Bose Einstein condensates to produce two level system (qubits) by exploiting the intrinsic nonlinear and the…
Why static bound-state calculations of tetraquarks should be met with scepticism
George Rupp, Eef van Beveren
Recent experimental signals have led to a revival of tetraquarks, the hypothetical hadronic states proposed by Jaffe in 1976 to explain the light scalar mesons. Meso…
Unquenching the meson spectrum: a model study of excited resonances
George Rupp, Susana Coito, Eef van Beveren
Quark models taking into account the dynamical effects of hadronic decay often produce very different predictions for mass shifts in the hadron spectrum. The consequences for meson…
