Digital-Analog quantum simulations using the cross-resonance effect
(American Physical Society, 2021-05-27)
[EN] Digital-analog quantum computation aims to reduce the currently infeasible resource requirements
needed for near-term quantum information processing by replacing sequences of one- and two-qubit
gates with a unitary ...
Reversible First-Order Single Crystal to Single Crystal Thermal Phase Transition in [(CH3)3CNH3]4[V4O12]
(MDPI, 2022-08-17)
[EN] The well-known compound tetrakis(tert-butylammonium)-cyclo-tetrametavanadate (V), [(CH3)3CNH3]4[V4O12] (1h_RT), which crystallizes in the tetragonal I4/m space group, undergoes an irreversible solid state transformation ...
Bi-Frequency Illumination: A Quantum-Enhanced Protocol
(Wiley, 2022)
Quantum-enhanced, idler-free sensing protocol to measure the response of a
target object to the frequency of a probe in a noisy and lossy scenario is
proposed. In this protocol, a target with frequency-dependent reflectivity ...
Energetic study of ultrasonic wettability enhancement
(Elsevier, 2021-11)
[EN]Many industrial and biological interfacial processes, such as welding and breathing depend directly on wettability and surface tension phenomena. The most common methods to control the wettability are based on modifying ...
Experimental Semi-Autonomous Eigensolver Using Reinforcement Learning
(Nature, 2021-06-10)
The characterization of observables, expressed via Hermitian operators, is a crucial task in quantum mechanics. For this reason, an eigensolver is a fundamental algorithm for any quantum technology. In this work, we implement ...
Shortcuts to adiabatic rotation of a two-ion chain
(IOP, 2021-10)
We inverse engineer fast rotations of a transversally tight, linear trap with two ions for a predetermined rotation angle and time, avoiding final excitation. Different approaches are analyzed and compared when the ions ...
Enhanced Connectivity of Quantum Hardware with Digital-Analog Control
