Heart Failure Detection Using Instance Quantum Circuit Approach and Traditional Predictive Analysis

open access: yesMathematics, 2023
The earlier prediction of heart diseases and appropriate treatment are important for preventing cardiac failure complications and reducing the mortality rate.

A unified approach to realize universal quantum gates in a coupled two-qubit system with fixed always-on coupling

open access: yes, 2005
We demonstrate that in a coupled two-qubit system any single-qubit gate can be decomposed into two conditional two-qubit gates and that any conditional two-qubit gate can be implemented by a manipulation analogous to that used for a controlled two-qubit ...

Simple operation sequences to couple and interchange quantum information between spin qubits of different kinds [PDF]

open access: yes, 2015
Efficient operation sequences to couple and interchange quantum information between quantum dot spin qubits of different kinds are derived using exchange interactions. In the qubit encoding of a single-spin qubit, a singlet-triplet qubit, and an exchange-

Reading a Single Qubit System Using Weak Measurement with Variable Strength [PDF]

open access: yes, 2016
Acquiring information about an unknown qubit in a superposition of two states is essential in any computation process. Quantum measurement, or sharp measurement, is usually used to read the information contents of that unknown qubit system.

Phonon-induced decoherence of a charge quadrupole qubit

open access: yesNew 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.

Tunable coupling in circuit quantum electrodynamics with a superconducting V-system

open access: yes, 2010
Recent progress in superconducting qubits has demonstrated the potential of these devices for the future of quantum information processing. One desirable feature for quantum computing is independent control of qubit interactions as well as qubit energies.

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

open access: yesNew 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

open access: yes, 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.

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

open access: yesCommunications 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 ...
