Enhanced Connectivity of Quantum Hardware with Digital-Analog Control
(American Physical Society, 2020-07-20)
Quantum computers based on superconducting circuits are experiencing rapid development, with the aim to outperform classical computers in certain useful tasks in the near future. However, the currently available chip ...
Superconducting circuit architecture for digital-analog quantum computing
(Springer, 2022)
[EN] We propose a superconducting circuit architecture suitable for digital-analog quantum computing (DAQC) based on an enhanced NISQ family of nearest-neighbor interactions. DAQC makes a smart use of digital steps (single ...
Speeding up quantum perceptron via shortcuts to adiabaticity
(Springer Nature, 2021-03-11)
The quantum perceptron is a fundamental building block for quantum machine learning. This is a multidisciplinary field that incorporates abilities of quantum computing, such as state superposition and entanglement, to ...
Green Alternative Cosolvents to N-Methyl-2-Pyrrolidone in Water Polyurethane Dispersions
(Royal Society Of Chemistry, 2021-06-05)
N-Methyl-2-pyrrolidone is a toxic dipolar aprotic solvent widely used in the synthesis of polyurethane dispersions (PUD). Since legislation strongly restricts this substance, green alternatives are essential. Dihydrolevo ...
Magnetic properties of permalloy antidot arrayfabricated by interference lithography
(American Institute of Physics, 2019-03)
The interference laser lithography and ion-beam sputtering have been reported. Magneto-optical Kerr effect magnetometry indicated that the sample exhibits four-fold anisotropic behaviour, i.e. different magnetization loops ...
The Role of Non-Covalent Interactions on Cluster Formation: Pentamer, Hexamers and Heptamer of Difluoromethane
(Wiley, 2021-07-26)
The role of non-covalent interactions (NCIs) has broadened with the inclusion of new types of interactions and a plethora of weak donor/acceptor partners. This work illustrates the potential of chirped-pulse Fourier transform ...
Magnetic nanostructures for emerging biomedical applications
(American Institute of Physics, 2020-01-28)
Magnetic nanostructures have been widely studied due to their potential applicability into several research fields such as data storage, sensing and biomedical applications. Focusing on the biomedical aspect, some new ...
Digital Quantum Rabi and Dicke Models in Superconducting Circuits
(Nature Publishing Group, 2014-12-15)
We propose the analog-digital quantum simulation of the quantum Rabi and Dicke models using circuit quantum electrodynamics (QED). We find that all physical regimes, in particular those which are impossible to realize in ...
The Forbidden Quantum Adder
(Nature Publishing Group, 2015-07-08)
Quantum information provides fundamentally different computational resources than classical information. We prove that there is no unitary protocol able to add unknown quantum states belonging to different Hilbert spaces. ...
Scalable quantum memory in the ultrastrong coupling regime
(Nature Publishing, 2015-03-02)
Circuit quantum electrodynamics, consisting of superconducting artificial atoms coupled to on-chip resonators, represents a prime candidate to implement the scalable quantum computing architecture because of the presence ...
