Quantum codes are crucial building blocks of quantum computers. With a self-dual quantum code is attached, canonically, a unique stabilised quantum state. Improving on a previous publication, we show how to determine the coefficients on the basis of kets

Preparation of Quantum Superposition Using Partial Negation
The preparation of a quantum superposition is the key to the success of many quantum algorithms and quantum machine learning techniques. The preparation of an incomplete or a non-uniform quantum superposition with certain properties is a non-trivial task.

A p-Adic Model of Quantum States and the p-Adic Qubit
We propose a model of a quantum N-dimensional system (quNit) based on a quadratic extension of the non-Archimedean field of p-adic numbers. As in the standard complex setting, states and observables of a p-adic quantum system are implemented by suitable ...

The link between classical and quantum theories is discussed in terms of extensional and intensional viewpoints. The paper aims to bring evidence that classical and quantum probabilities are related by intensionalization, which means that by abandoning ...

We extend the theory of quantum state engineering (QSE) to the open quantum systems which simultaneously suffer time-dependent decoherence and time-independent decoherence.

The Operational Choi–Jamiołkowski Isomorphism
In this article, I use an operational formulation of the Choi–Jamiołkowski isomorphism to explore an approach to quantum mechanics in which the state is not the fundamental object.

High-performance cavity-enhanced quantum memory with warm atomic cell
Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and ...

On the determination of pure quantum states by the homodyne detection
The methods of reconstruction of the wave function of a pure state of a quantum system by quadrature distribution measured experimentally by the homodyne detection are considered.
