Demonstration of an LLO CV-QKD system over 12 km of optical fiber
Christiano M. S. Nascimento, Artur A. Matoso, Gustavo C. Amaral +1
Continuous-variable quantum key distribution (CV-QKD) promises high rates and seamless integration with classical beams within a single optical fiber. Over the years, implementatio…
Fraud detection in credit card transactions using Quantum-Assisted Restricted Boltzmann Machines
João Marcos Cavalcanti de Albuquerque Neto, Gustavo Castro do Amaral, Guilherme Penello Temporão
Use cases for emerging quantum computing platforms become economically relevant as the efficiency of processing and availability of quantum computers increase. We assess the perfor…
Passive polarization and phase stabilization scheme for Twin-Field QKD
Christiano M. S. Nascimento, Felipe Calliari, Guilherme P. Temporão
Twin-Field Quantum Key Distribution requires first-order interference between coherent states sent by Alice and Bob in a mid-station Charlie. In order to obtain stable operation an…
Two-photon quantum state tomography of photonic qubits
Guilherme P. Temporão, Pedro Ripper, Thiago B. Guerreiro +1
We provide a tool for measuring the Stokes parameters and the degree of polarization of single photons by employing second order interference, namely the Hong-Ou-Mandel (HOM) inter…
Swap Test-based Characterization of Quantum Processes in Universal Quantum Computers
Pedro Ripper, Gustavo Amaral, Guilherme Temporão
Quantum Computing has been presenting major developments in the last few years, unveiling systems with a increasing number of qubits. However, unreliable quantum processes in unive…
Relaxing constraints on data acquisition and position detection for trap stiffness calibration in optical tweezers
Bruno Melo, Felipe Almeida, Guilherme Temporão +1
Optical tweezers find applications in various fields, ranging from biology to physics. One of the fundamental steps necessary to perform quantitative measurements using trapped par…
