Special seminar: Marco Piani

Operational characterization of quantum properties

Marco Piani, University of Strathclyde

 Quantum features like quantum superposition and quantum correlations — the latter comprising, but not limited to entanglement — are both of foundational and applicative interest. We develop tools to characterize such features operationally, looking for ways to detect, quantify, and utilize them. Some recent results I will report on regard the use of such features in the discrimination of physical processes, a task within the area of quantum metrology.

Special seminar: Rajibul Islam

Quantum simulation with laser-cooled trapped ions

Rajibul Islam, Institute for Quantum Computing

Laser-cooled trapped ions are among the most versatile experimental platforms for the simulation of non-trivial quantum Hamiltonians. What distinguishes this platform from others is the extent to which it is experimentally possible to control this system at the level of individual particles and interactions between them.

Out-of-equilibrium dynamics in AMO quantum simulators

Andrew Daley, University of Strathclyde

Over the past few years, the possibility to control and measure atomic and molecular systems time-dependently has generated a lot of progress in exploring out-of-equilibrium dynamics for strongly interacting many-particle systems. This connects directly to fundamental questions relating to the relaxation of such systems to equilibrium, as well as the spreading of correlations and build-up of entanglement.

Quantum Information Enabled Neutron Interferometry

Joachim Nsofini, IQC

In the quest to explore big quantum systems, there have been opportunities to explore smaller quantum system like the neutron interferometer. A neutron interferometer (NI) has proven to be a useful tool in the study of quantum effects ranging from  experiments with single particle interference to measuring quantities of significant importance in condensed-matter and Standard Model physics.

Colloquium: Leonid Pryadko

Dephasing with strings attached

Leonid Pryadko, University of California, Riverside

Is there a difference between the quantum dynamics of a "real" particle and a collective excitation, like that in a spin ice, which creates a measurable gauge field? I will argue that in the presence of weak dephasing, the answer depends on the quantity measured.

Special seminar: Abel Molina

The optimality of projections for quantum state exclusion

Abel Molina, IQC

We will first motivate the problem of quantum state exclusion of pure states, through its connections with the PBR game and with compatibility conditions for quantum state assignments. Then, we will discuss our recent result regarding the optimality of projections for perfect state exclusion of 3 pure states in 3 dimensions (arXiv:1702.06449).

Colloquium: Hakan Tureci

A platform to study many-body physics with photons

Hakan Tureci, Princeton University

The past decade has seen enormous experimental progress in building superconducting electrical circuits featuring artificial atoms subject to the quantized electromagnetic field of microwave photons. The fabrication and control of superconducting circuits has reached a stage where many such elements can be wired up into intricate networks, allowing the preparation and readout of complex quantum states of photons and atoms.

Quantum science and technology at QuTech (Delft, NL)

Julia Cramer, QuTech Delft

QuTech is an advanced research center for quantum computing and the quantum internet, addressing scientific and engineering challenges in collaboration with industrial partners. QuTech is striving to remain at the forefront in quantum information science and technology. I’ll give some info on the development of QuTech over the years. Furthermore, I will present what the goals and focusses are of our research teams, current work and latest milestones.

Seminar: Pranjal Bordia

Many-Body Localization Through the Lens of Ultracold Quantum Gases

Pranjal Bordia, Max Planck Institute, Munich

A fundamental assumption of quantum statistical mechanics is that closed isolated systems always thermalize under their own dynamics. Progress on the topic of many-body localization has challenged this vital assumption, describing a phase where thermalization, and with it, equilibrium thermodynamics, breaks down.
