Theory of open quantum systems, decoherence, and quantum thermodynamics

The Group of Quantum Information and Quantum Computation of Complutense University of Madrid is offering a predoctoral research position to undertake a PhD in “Theory of open quantum systems, decoherence, and quantum thermodynamics”. These cutting-edge areas bridge fundamental concepts in physics with emerging applications in quantum technologies.

What is the project about?
The study of open quantum systems focuses on understanding how quantum systems interact with their environment, a critical aspect in the design and control of real-world quantum devices. Decoherence is one of the greatest challenges for implementing quantum computing and other systems based on quantum physics, as well as for understanding the quantum-to-classical transition, as it describes how quantum properties are lost due to environmental effects. Quantum thermodynamics aims to extend classical concepts such as energy, work, and entropy into the quantum domain, unveiling new laws and possibilities that could revolutionize our understanding of nature.

This project is oriented toward researching the dynamics and thermodynamics of strongly open quantum systems, which are systems that interact strongly with their environment. Specifically, it aims to develop efficient methods to describe the dynamics of these systems—where standard perturbative techniques are inadequate—and to formulate thermodynamic laws within this context.

The topic has profound implications in areas such as:
– Fundamental physics: Exploring the boundaries between quantum mechanics and thermodynamics, with potential implications for other fields in physics.
– Quantum information: Understanding and manipulating information and its physical properties in the quantum realm.
– Quantum technologies: Discovering new quantum phenomena to design advanced technological devices optimized for error resistance.

We seek a candidate with:
– A solid background in theoretical physics and mathematics.
– Preferable knowledge in quantum mechanics, quantum information, quantum
field theory, statistical mechanics, or related areas.
– A strong academic record, motivation, and interest in learning and
contributing in a multidisciplinary research environment.

We offer:
– A Phd contract to develop a PhD thesis within a dynamic and leading research group.
– Opportunities for international collaboration with renowned research groups and participation in high-impact projects.
– Additional funding for attending conferences, workshops, and summer schools in advanced quantum physics and related areas.
– Training in advanced research techniques and tools.
– Participation in a collaborative and stimulating research environment that fosters creativity and idea exchange.
– High-impact research opportunities: The project addresses fundamental questions about the limits of quantum physics, the origins of decoherence, and the interplay between information, entropy, and energy. These topics are deeply connected to frontier conceptual problems while also ensuring practical applications.
