Emergent quantum randomness and its application for quantum device benchmarking
In this talk, we describe a novel, universal phenomenon that occurs in strongly interacting many-body quantum dynamics beyond the conventional thermalization.
Double Feature: Memory and optimization with multimode cavity QED; Transverse-Field Ising Dynamics by Rydberg Dressing in a cold atomic gas
In this first talk, I will describe how a driven-dissipative system is realized by coupling ultracold atoms to a multimode optical cavity and how it can perform various computational tasks.
In this second talk, we will present a realization of long-range optically-controllable Ising interactions in a cold gas of cesium atoms by Rydberg dressing.
Quantum probes of two-dimensional materials
Spin qubits based on diamond NV centers can detect tiny magnetic fields; thin two-dimensional materials produce tiny magnetic fields. Do they make a good match? I will discuss two works that explored how NV magnetometry can uniquely probe the spins and currents in crystals that are ...
Double Feature: A photonic quantum computer design with only one controllable qubit; Towards MEMS-driven photonic computing
Talk #1: We describe a design for a photonic quantum computer which requires minimal quantum resources: a single coherently-controlled atom.
Talk #2: Programmable nanophotonic networks of Mach-Zehnder interferometers are energy-efficient circuits for matrix-vector multiplication that benefit a wide variety of applications such as artificial intelligence, quantum computing and cryptography.
Continuous variables quantum complex networks
Experimental procedures based on optical frequency combs and parametric processes produce quantum states of light involving large numbers of spectro-temporal modes that can be mapped and analyzed in terms of quantum complex networks.
Double Feature: Ultra-low-power second-order nonlinear optics on a chip; Quantum Dynamics of Ultrafast Nonlinear Photonics
Talk #1: Thin-film lithium niobate is a promising platform for integrated photonics because it can tightly confine light in small waveguides which allows for large interactions between light, microwaves, and mechanics.
Talk #2: Broadband optical pulses propagating in highly nonlinear nanophotonic waveguides can significantly leverage optical nonlinearity by tight temporal and spatial field confinements, promising a route towards all-optical quantum engineering and information with single-photon nonlinearities.
Quantum sensing with unlimited optical bandwidth
Squeezed light is a major resource for quantum sensing, which has been already implemented in high-end interferometric sensing, such as gravitational wave detection. However, standard squeezed interferometry methods suffer from two severe limitations.
Unconventional computing with liquid light
The recent advances in the development of physical platforms for solving combinatorial optimisation problems reveal the future of high-performance computing for quantum and classical devices.
Coupling diamond defects to high-finesse optical microcavities
Defect centers in diamond can offer atomic-like optical transitions and long-lived spin degrees of freedom.
Direct laser cooling of polyatomic molecules
Laser cooling and evaporative cooling are the workhorse techniques that have revolutionized the control of atomic systems.
Towards quantum and classical light sources and transducers at any wavelength using nonlinear nanophotonics
Nanophotonics provides the unprecedented opportunity to engineer nonlinear optical interactions through the nanometer-scale control of geometry provided by modern fabrication technology.
Lattice atom interferometry in an optical cavity
Atom interferometers are powerful tools for both measurements in fundamental physics and inertial sensing applications.
