Encoding a logical qubit into physical qubits [PDF]

Physical Review A, 2005
We propose two protocols to encode a logical qubit into physical qubits relying on common types of qubit-qubit interactions in as simple forms as possible. We comment on its experimental implementation in several quantum computing architectures, e.g.

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.

A Qubit Represented by the Oscillator’s Quantum States in Magnetic Resonance Force Microscopy

Magnetochemistry, 2022
We consider magnetic resonance force microscopy (MRFM) in the situation when the frequency of the electron spin resonance matches the fundamental frequency of the cantilever with a ferromagnetic particle attached to its tip.

Valence holes as Luttinger spinor based qubits in quantum dots

, 2009
We present a theory of valence holes as Luttinger spinor based qubits in p-doped self-assembled quantum dots within the 4-band $k\cdot p$ formalism. The two qubit levels are identified with the two chiralities of the doubly degenerate ground state.

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.

Quantum state transfer and Hadamard gate for coherent states

, 2013
We propose a quantum state transfer from an atomic qubit to a cat-like qubit by means of one degenerate Raman interaction and one Hadamard gate operation for coherent states.

Adenosine‐to‐inosine editing of miR‐200b‐3p is associated with the progression of high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

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
