Tight Bell inequalities from polytope slices
José Jesus, Emmanuel Zambrini Cruzeiro
We derive new tight bipartite Bell inequalities for various scenarios. A bipartite Bell scenario is defined by the numbers of settings and outcomes per party, , …
Qubit Picture of Virtual Particles
Gonçalo M. Quinta
We show that virtual particles, despite being unobservable, can be described by quantum operators which can be interpreted under certain conditions as valid qubit quantum states. F…
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…
Classical Half-Adder using Trapped-ion Quantum Bits: Towards Energy-efficient Computation
Sagar Silva Pratapsi, Patrick H. Huber, Patrick Barthel +3
Reversible computation has been proposed as a future paradigm for energy efficient computation, but so far few implementations have been realised in practice. Quantum circuits, run…
Super-resolution of Green's functions on noisy quantum computers
Diogo Cruz, Duarte Magano
Quantum computers, using efficient Hamiltonian evolution routines, have the potential to simulate Green's functions of classically-intractable quantum systems. However, the decoher…
Connecting XOR and XOR* games
Lorenzo Catani, Ricardo Faleiro, Pierre-Emmanuel Emeriau +2
In this work we focus on two classes of games: XOR nonlocal games and XOR* sequential games with monopartite resources. XOR games have been widely studied in the literature of nonl…
