Phonon-induced decoherence of a charge quadrupole qubit

New Journal of Physics, 2018
Many quantum dot qubits operate in regimes where the energy splittings between qubit states are large and phonons can be the dominant source of decoherence.

Kagome qubit ice

Nature Communications, 2023
AbstractTopological phases of spin liquids with constrained disorder can host a kinetics of fractionalized excitations. However, spin-liquid phases with distinct kinetic regimes have proven difficult to observe experimentally. Here we present a realization of kagome spin ice in the superconducting qubits of a quantum annealer, and use it to demonstrate

Targeting RNA with small molecules using state-of-the-art methods provides highly predictive affinities of riboswitch inhibitors

Communications Biology
Targeting RNA with small molecules represents a promising yet relatively unexplored avenue for the design of new drugs. Nevertheless, challenges arise from the lack of computational models and techniques able to accurately model RNA systems, and predict ...

Quantum state estimation when qubits are lost: a no-data-left-behind approach

New Journal of Physics, 2017
We present an approach to Bayesian mean estimation of quantum states using hyperspherical parametrization and an experiment-specific likelihood which allows utilization of all available data, even when qubits are lost.

Characterizing the salivary RNA landscape to identify potential diagnostic, prognostic, and follow‐up biomarkers for breast cancer

Molecular Oncology, EarlyView.
This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

Polylogarithmic-depth controlled-NOT gates without ancilla qubits

Nature Communications
Controlled operations are fundamental building blocks of quantum algorithms. Decomposing n-control-NOT gates (C n (X)) into arbitrary single-qubit and CNOT gates, is a crucial but non-trivial task.

Teoria quântica da informação: impossibilidade de cópia, entrelaçamento e teletransporte

Revista Brasileira de Ensino de Física
A idéia de desenvolver computadores cuja dinâmica obedeça às leis da Mecânica Quântica data do Ultimo quarto do seculo XX e assume, nos dias de hoje, importancia tecnológica e cientifica notável, uma vez que o uso de algoritmos quânticos se disseminou na
