Entanglement of superconducting qubits via acceleration radiation
(Nature Publishing, 2017-04-06)
We show that simulated relativistic motion can generate entanglement between artificial atoms and protect them from spontaneous emission. We consider a pair of superconducting qubits coupled to a resonator mode, where the ...
Secure quantum remote state preparation of squeezed microwave states
(Nature Publishing, 2019-06-13)
Quantum communication protocols based on nonclassical correlations can be more efficient than known classical methods and offer intrinsic security over direct state transfer. In particular, remote state preparation aims ...
Symmetries and Invariants for Non-Hermitian Hamiltonians
(MDPI, 2018-07)
We discuss Hamiltonian symmetries and invariants for quantum systems driven by non-Hermitian Hamiltonians. For time-independent Hermitian Hamiltonians, a unitary or antiunitary transformation AHA that leaves the Hamiltonian ...
Analog simulator of integro-differential equations with classical memristors
(Nature Publishing, 2019-09-10)
An analog computer makes use of continuously changeable quantities of a system, such as its electrical, mechanical, or hydraulic properties, to solve a given problem. While these devices are usually computationally more ...
Efficient Broadband Frequency Conversion via Shortcuts to Adiabaticity
(Wiley, 2022-12)
The method of adiabatic frequency conversion, in analogy with a two-level atomic system, has been put forward recently and verified experimentally to achieve robust frequency mixing processes such as sum and difference ...
Toward Pricing Financial Derivatives with an IBM Quantum Computer
(American Physical Society, 2021-02-22)
Pricing interest-rate financial derivatives is a major problem in finance, in which it is crucial to accurately reproduce the time evolution of interest rates. Several stochastic dynamics have been proposed in the literature ...
Fast transport of Bose-Einstein condensates in anharmonic traps
(Royal Society, 2022-12)
We present a method to transport Bose-Einstein condensates (BECs) in anharmonic traps and in the presence of atom-atom interactions in short times without residual excitation. Using a combination of a variational approach ...
Optimally robust shortcuts to population inversion in two-level quantum systems
(IOP Publishing LTD, 2012-09-21)
We examine the stability versus different types of perturbations of recently proposed shortcuts to adiabaticity to speed up the population inversion of a two-level quantum system. We find the optimally robust processes by ...
Finite-time quantum entanglement in propagating squeezed microwaves
(Nature Publishing, 2018-04-23)
Two-mode squeezing is a fascinating example of quantum entanglement manifested in cross-correlations of non-commuting observables between two subsystems. At the same time, these subsystems themselves may contain no quantum ...
A journey across dopamine Metabolism: A rotational study of DOPAC
(Elsevier, 2023-04)
DOPAC, a relevant scaffold in dopamine metabolism, was probed in the gas phase and interrogated by high-resolution rotational spectroscopy. Herein, three distinct conformers were isolated in a supersonic jet and identified ...
