Aggregating Quantum Networks [PDF]
OSA Advanced Photonics Congress 2021, 2020 The implementation of quantum error-correction codes needs high efficiency transmission channels and significant physical resources. Here we show that aggregating quantum networks alleviate those issues when applied to the quantum Reed-Salomon code.

Journal of Computer and System Sciences, 2001 This paper initiates the study of quantum computing within the constraints of using a polylogarithmic ($O(\log^k n), k\geq 1$) number of qubits and a polylogarithmic number of computation steps. The current research in the literature has focussed on using a polynomial number of qubits. A new mathematical model of computation called \emph{Quantum Neural

Active Magnetic-Field Stabilization with Atomic Magnetometer
Sensors, 2020 A magnetically-quiet environment is important for detecting faint magnetic-field signals or nonmagnetic spin-dependent interactions. Passive magnetic shielding using layers of large magnetic-permeability materials is widely used to reduce the magnetic ...

Reconstructing Quantum States With Quantum Reservoir Networks [PDF]
IEEE Transactions on Neural Networks and Learning Systems, 2021 Reconstructing quantum states is an important task for various emerging quantum technologies. The process of reconstructing the density matrix of a quantum state is known as quantum state tomography. Conventionally, tomography of arbitrary quantum states is challenging as the paradigm of efficient protocols has remained in applying specific techniques ...

Polariton dynamics in one-dimensional arrays of atoms coupled to waveguides
New Journal of Physics, 2022 Photons strongly coupled to material systems constitute a novel system for realizing non-linear optics at the level of individual photons and studying the dynamics of non-equilibrium quantum many-body system.
