Quantum networks and computations with spins in diamond.
Tim Hugo Taminiau
QuTech, Netherlands, The
Electron-nuclear spin systems based on optically active defects in diamond provide a promising platform for distributed quantum simulations and computation. In this approach, optically active defect spins are used to form multi-qubit processors that can be linked together in a network through photonic links [1,2]. Quantum error correction and computations are then distributed over the network.
In this talk I will introduce such spin-based distributed quantum computations and present our recent progress. In particular, we have recently shown that it is possible to control large numbers of nuclear spins around a single NV center , and to use these qubits for quantum simulations of many-body physics  and for encoding fault-tolerant logical qubits .

Coherent anti-Stokes Raman scattering is an extremely powerful non-linear optical (NLO) microscopy technique for label-free vibrational imaging allowing for a detailed study of biological samples in their native state. To overcome the long acquisition times associated with raster sample scanning required in NLO microscopy, which impair real-time investigation of fast biological dynamics, we employ here wide-field signal generation over a large field of view, covering tens of micrometers. To this aim, we exploit an innovative approach based on the use of an amplified femtosecond ytterbium laser source delivering high energy (≈μJ) pulses in the near infrared. This enables the generation of stable broadband Stokes pulses to measure the entire fingerprint region of the molecular vibrational spectrum, the richest in chemical information. Our results pave the way for future translational applications and clinical diagnostics with video-rate imaging capabilities.

We present the first demonstration of propagation-invariant space-time (ST) wave packets localized in all dimensions. By introducing orbital-angular-momentum into the wave packets, we produce propagation-invariant ST-OAM wave packets traveling at arbitrary group velocities.

Non-locality and single object spectroscopy in THz Landau polaritons
1Insititute for Quantum Electronics, ETH Zürich, Switzerland; 2Department of Physics and Astronomy, Univ. of Southampton, UK
We will discuss, theoretically and experimentally, the existence of a limit to the possibility of arbitrarily increasing electromagnetic confinement in polaritonic systems. Strongly sub-wavelength fields can excite a continuum of high-momenta propagative magnetoplasmons. This leads to peculiar nonlocal polaritonic effects, as certain polaritonic features disappear and the system enters in the regime of discrete-to-continuum strong coupling. We will as well discuss experiments reporting spectroscopy of a single, ultrastrongly coupled, highly subwavelength resonator operating at 300 GHz.
