The Quantum Photonics Group at the Université de Moncton (the largest Francophone university in Canada outside Quebec), led by Dr. Lambert Giner, is looking for a motivated graduate student for an MSc in physics. The project focuses on developing new techniques to characterize quantum states without disturbing them — a fundamental and genuinely tricky problem that sits at the heart of modern quantum physics.

We open a PhD position in our group at the Université de Bordeaux and CNRS.

Motivation:
Optically trapped particles, isolated from environmental noise by the optical potential, offer an unparalleled platform to explore quantum behavior at mesoscopic scales. Their weak coupling to the environment and precise optical control make them ideal for investigating fundamental quantum phenomena and developing quantum technologies.

Coupling quantum emitters to the optical modes of a photonic lattice creates new opportunities for engineering exotic quantum light sources and developing novel quantum simulators with long-range interactions. It would allow studying non-classical states with spread entanglement and the implementation of strongly correlated phases of light.

Two openings in quantum memories in microgravity at Humboldt-Universität zu Berlin

Humboldt-Universität zu Berlin is advertising two research fellow positions in experimental quantum memories in microgravity at the Department of Physics, Faculty of Mathematics and Natural Sciences, Berlin.

• Research fellow (m/f/d) in the field of quantum memories with warm atoms in microgravity (DR/060/26)

Epitaxial semiconductor quantum dots are among the best sources of quantum states of light. They deliver single photons and entangled photon pairs with high brightness and indistinguishability. We have recently established new methods for their coherent optical control and excitation with the goals of improving robustness and coherence. In the Austrian Science Fund (FWF) project BRAIDS we are working towards the generation of time-bin entanglement via dark exciton states.

The Niels Bohr Institute invites applicants for two PhD fellowships in Theoretical Quantum Optics and Quantum Information. The projects will be part of the theoretical quantum optics group and the Center for Hybrid quantum Networks (Hy-Q).

The starting date is (expected to be) 1 September 2026 or as soon as possible thereafter. An earlier starting date may also be a possibility.

Background: This postdoctoral researcher will join the newly established group of Inamori FP Associate Professor Joshua Foo at the Institute for Advanced Study, Kyushu University. The research will focus on developing experimental proposals to probe the interplay of quantum mechanics and spacetime physics in low-energy systems such as atomic clocks, mechanical resonators, and photonic interferometers. Relevant directions for exploration include quantum extensions of relativistic principles, foundations of relativistic quantum mechanics, and tabletop tests of weak field quantum gravity.

The coherence time is a key metric for evaluating the performance of a quantum bit. We have recently proposed a new type of qubit that stores information in the mechanical displacement of a carbon nanotube and leverages its coupling to an electronic two-level system to induce sufficiently strong anharmonicity, enabling its manipulation and readout.
