The generation of entanglement between distant quantum systems is at the core networking. In recent years, numerous theoretical protocols for remote-entanglement have been proposed, many which experimentally realized. Here, we provide a modular framework to elucidate general mechanisms photon-mediated single spins in atomic or solid-state systems. Our categorizes existing various levels abstraction and allows combining elements different schemes new ways. These layers make it possible...
Constrictive pericarditis is an uncommon complication of idiopathic long thought to be irreversible, often requiring pericardiectomy ensure recovery. Recently, transient constriction has been described in the setting long-standing with active inflammation. We report case a 16-year-old male relapsing-remitting pericarditis, refractory non-steroidal anti-inflammatory drugs (NSAIDs), who developed constrictive physiology. Despite proper tapering, patient five relapses during steroid treatment,...
Solid-state quantum registers consisting of optically active electron spins with nearby nuclear are promising building blocks for future technologies. For spin-1 registers, dynamical decoupling (DD) gates have been developed that enable the precise control multiple spin qubits. However, important class spin-<a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mrow><a:mn>1</a:mn><a:mo>/</a:mo><a:mn>2</a:mn></a:mrow></a:math> systems, this method suffers from intrinsic...
Color centers integrated with nanophotonic devices have emerged as a compelling platform for quantum science and technology. Here, we integrate tin-vacancy in diamond waveguide investigate the interaction light at single-photon level both reflection transmission. We observe single-emitter-induced extinction of transmitted up to 25% measure nonlinear effect on photon statistics. Furthermore, demonstrate fully tunable interference between reflected field laser backscattered fiber end show...
Diamond tin-vacancy centers have emerged as a promising platform for quantum information science and technology. A key challenge their use in more-complex experiments scalable applications is the ability to prepare center desired charge state with optical transition at predefined frequency. Here we report on heralding such successful preparation using combination of laser excitation, photon detection, real-time logic. We first show that fluorescence counts collected during an optimized...
We report on the first radioactive beam experiment performed at recently commissioned REX-ISOLDE facility CERN in conjunction with highly efficient gamma spectrometer MINIBALL. Using 30Mg ions accelerated to an energy of 2.25 MeV/u together a thin (nat)Ni target, Coulomb excitation excited 2+ states projectile and target nuclei well below barrier was observed. From measured relative deexcitation gamma-ray yields B(E2;0(+)gs-->2(+)1) value determined be 241(31)e2 fm4. Our result is lower than...
COVID-19 is strongly influenced by age and comorbidities. Acute kidney injury (AKI) a frequent finding in patients seems to be associated mortality severity. On the other hand, role of dysfunction still debated. We performed retrospective study cohort 174 hospitalized Italy from March 3rd May 21st 2020, investigate on severity mortality. Moreover, we examined depth relationship between function, age, progression COVID-19, also using different equations estimate glomerular filtration rate...
Efficient coupling of optically active qubits to optical cavities is a key challenge for solid-state-based quantum optics experiments and future technologies. Here we present photonic interface based on single tin-vacancy center in micrometer-thin diamond membrane coupled tunable open microcavity. We use the full tunability microcavity selectively address individual centers within cavity mode volume. Purcell enhancement transition evidenced both by excited state lifetime reduction linewidth...

The HIE-ISOLDE project at CERN proposes a superconducting upgrade to increase the energy range and quality of radioactive ion beams produced ISOLDE, which are currently postaccelerated by normal conducting beam experiment linac. specification design choices for linac outlined along with comprehensive dynamics study undertaken understand mitigate sources emittance dilution. dominant cause transverse growth was attributed coupling between longitudinal motions through phase dependence rf...
In single-particle or intraparticle entanglement, two degrees of freedom a single particle, e.g., momentum and polarization photon, are entangled. Single-particle entanglement (SPE) provides source non classical correlations which can be exploited both in quantum communication protocols experimental tests noncontextuality based on the Kochen-Specker theorem. Furthermore, SPE is robust under decoherence phenomena. Here, we show that entangled states photons produced from attenuated sources...
