Position We look for outstanding and motivated candidates with a Master related to Physics and a background in Quantum Physics to pursue a PhD at IFISC (UIB-CSIC), Spain. The 3-year PhD position, supervised by Dr. Albert Cabot, will involve theoretical research on the dynamics of open quantum systems and their applications in sensing and reservoir computing. The project will focus on nonequilibrium phenomena, such as time-crystal phases, dissipative phase transitions, or synchronization, in systems inspired by current trapped-ion and atom–cavity setups. The aim is to uncover how these behaviors emerge, to characterize their signatures in emitted light, and to determine how continuous measurements can qualitatively alter the system’s dynamics. The research will also explore two application areas. Quantum metrology: studying how nonequilibrium regimes influence parameter-estimation sensitivity and developing measurement protocols based on monitoring the system’s emission. See [1] for a reference. Machine learning: in collaboration with Profs. R. Zambrini and G. L. Giorgi, implementing reservoir-computing schemes that use these phenomena as computational resources and analyzing how to realize them in concrete physical setups. See [2] for a reference. The successful candidate will enroll in the PhD Program in Physics of the University of the Balearic Islands, which has been awarded the Excellence Mention of ANECA. Candidates must be resident in Spain before the start of the contract. Expected start date: September 2026.Application deadline: 31st of May 2026. References:[1] A. Cabot, F. Carollo, I.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
The transition of quantum technologies from theoretical frameworks to practical implementation requires a robust understanding of open quantum systems, where interaction with the environment is the primary determinant of operational stability. This role type exists to bridge the gap between abstract dissipative dynamics and functional applications in sensing and information processing, addressing a critical bottleneck in the current quantum value chain. By focusing on nonequilibrium phenomena and continuous measurement, these researchers enable the translation of fundamental physics into high-sensitivity metrology and novel computational architectures. The structural necessity for this expertise is driven by sector-wide market signals indicating that the management of decoherence is no longer just a noise-mitigation strategy but a core architectural feature. As the industry advances toward higher Technology Readiness Levels (TRL), the ability to exploit open system dynamics serves as a vital credibility signal for the maturity of next-generation quantum hardware. This role ensures that the foundational principles of quantum mechanics are successfully coupled with emerging classical-quantum hybrid workflows for industrial-scale utility.
Within the broader quantum ecosystem, the study of open systems is positioned at the intersection of fundamental research and systems-level enablement. As quantum hardware architectures—specifically trapped-ion and atom-cavity setups—move from laboratory prototypes to pilot production, the industry faces significant macro constraints in managing system-environment coupling. Current workforce data from the QED-C and similar bodies highlight a persistent shortage of researchers capable of navigating the complex interface between dissipative phase transitions and practical device performance. This expertise is critical for overcoming scalability barriers, as it provides the theoretical grounding necessary to maintain coherence in increasingly larger and more complex quantum systems.
Sector dynamics are currently defined by a shift toward identifying practical "quantum advantage" through specialized applications such as quantum reservoir computing and high-precision sensing. The research focus on nonequilibrium regimes represents a strategic move away from idealistic closed-system models toward the messy, non-stationary realities of real-world deployment. This alignment is essential for the integration of quantum systems into existing classical high-performance computing (HPC) infrastructures, where continuous-variable models and dissipative control protocols offer a potential pathway to fault tolerance without the prohibitive overhead of traditional error correction codes.
Furthermore, the European quantum landscape, bolstered by initiatives like the Quantum Flagship and national strategic programs, relies on the high-level output of specialized institutes to maintain sovereign technological capabilities. The coupling of machine learning with quantum dynamics is a notable trend, reflecting an industry-wide move toward "quantum-aware" classical algorithms that can simulate or assist quantum processes. As public and private funding cycles prioritize TRL progression, the role of academic-industrial translation becomes paramount, ensuring that deep-tech discoveries in synchronization or time-crystals are mapped directly to future commercial roadmaps in telecommunications, finance, and defense.
The capability architecture for this role type centers on the sophisticated modeling of non-unitary evolution and the characterization of light-matter interfaces. At the foundational layer, mastery of the Master Equation and quantum trajectory methods is required to simulate how open systems evolve under the influence of external baths. This is coupled with expertise in continuous measurement theory, which serves as the technical interface for real-time system monitoring and feedback control. Such capabilities are indispensable for ensuring the structural throughput of quantum metrology, where parameter-estimation sensitivity is directly limited by the accuracy of the dissipative model.
Beyond theoretical modeling, the role facilitates a cross-functional coupling between quantum optics and reservoir computing, where physical phenomena are leveraged as computational resources. This technical interface allows for the development of hardware-efficient machine learning models that can operate on noisy, intermediate-scale quantum (NISQ) devices. By standardizing the analytical framework for signatures in emitted light, researchers enable a level of diagnostic precision that allows engineering teams to optimize hardware design for specific environmental constraints. This capability is essential for the long-term stability and interoperability of quantum-secure communication networks.
