It also has an Advanced Technology Unit supporting experimental research requiring cutting-edge technology. 

Description of the postdoctoral position

The candidate is expected to contribute substantially to the ICCUB-Maria de Maeztu Challenge: Exploiting quantum resources for science and technology

The rapidly unfolding second quantum revolution hinges on harnessing quantum entanglement and superposition to advance our understanding of nature at a fundamental level and to develop novel technologies. Key facets include quantum communication, computation, hardware, sensing, and imaging, with potential extensive applications across scientific and technological domains.

These developments are poised to have an unprecedented impact on communication security and on our computational capacity, driving global efforts in this field. Quantum hardware represents the current frontier, involving development of entangled-source qubits, quantum memories, quantum networks and sensors.

We take on this challenge with a strong multidisciplinary drive, a newly established quantum communications laboratory, and quantum computation and simulation. The latter includes basic science contributions to quantum simulation, and the development of algorithms to advance our understanding of many-body quantum systems with quantum computers.

The Institute of Cosmos Sciences of the University of Barcelona (ICCUB) invites applications for a 3-year Postdoctoral position in gravitational wave astronomy, as part of its current call for two postdoctoral positions and one ICCUB Postdoctoral Fellowship, offered under the framework of its Unit of Excellence Maria de Maeztu. 

The successful candidate will lead projects spanning both theoretical and data analysis aspects of gravitational wave science. Research topics may include, but not be limited to parameter estimation, gravitational lensing, numerical relativity simulations, detector characterization, mock data generation, neutron star asteroseismology, magnetohydrodynamic modeling of neutron stars and multimessenger signals, stellar/BH dynamics, tests of general relativity, relations to high energy and nuclear physics and connections to holography. The ICCUB is a member of the LVK Collaboration, the Einstein Telescope Collaboration and is contributing to the LISA mission on theoretical models, computing and instrumentation activities. We are also part of the Spanish RedONGRA network (Red Nacional en Ondas Gravitacionales), which fosters national collaboration in gravitational wave research. In addition, we are actively participating in surveys (ESA-Gaia, Weave, SDSS-IV) and EM follow-up missions at various wavelengths (BlackGEM, MAGIC and LSST), which allow scientists at the ICCUB (https://icc.ub.edu/research/gravitational-waves) to build an end-to-end understanding of all steps leading to GW sources. Prior research experience in gravitational wave data analysis is preferred, but not strictly required. Experience with large-scale computation, Bayesian methods, and/or machine learning/AI is considered a plus.
