Efficient fiber-coupled single-photon sources based on quantum dots

Speaker's Institution: 
Niels Bohr Institute

Many photonic quantum information processing applications would benefit from a high brightness, fiber-coupled source of triggered single photons. Sources based on quantum dots coupled to nanophotonic waveguides are very promising candidates as they feature a near-unity emitter-waveguide coupling efficiency. The main challenge remains to implement an efficient way to transfer the photons off-chip to an optical fiber.

PT Symmetry and Exceptional Points in Open Systems

Date:

Speaker's Institution: 
Quantum Optics and Quantum Information, Miami University

Many of the new wave of nanophotonic structures are described in terms of PT symmetry. Many interesting effects have been studied and observed based on this formalism. Originally developed for complex potentials, which may still yield real eigenvalues for the dynamics, it has use in systems with gain and loss. As we will show, the usual application of PT in optics is to describe mean field theory do not adequately describe quantum noise. It is essentially quantum trajectory theory without the jumps.

Optical quantum fingerprinting using higher-order interference

Date: 
February 5, 2018 - 4:00pm
Speaker: 
Michal Jachura
Speaker's Institution: 
University of Warsaw
We propose and discuss a novel optical quantum fingerprinting protocol which does not require a shared phase reference between the communicating parties. We show that the scaling of the protocol, in terms of transmittable classical information, is analogous to the recently proposed and demonstrated schemes based on coherent pulses and first-order optical interference [1,2]. The protocol performance is quantified with the help of Chernoff information.

Applications of a scanning low energy electron microscope

Speaker's Institution: 
Institute of Scientific Instruments of the CAS, Brno, Czech Republic

Scanning low energy electron microscopes (SLEEM) operating with primary beam energy below 500 eV have proved to be a powerful tool for investigating many samples that are difficult to being observed using standard (S)TEM techniques. In case of low energies an appropriate strategy of collecting detecting signal electrons is important to have a sufficient signal and reasonable contrast. Many principles were developed for this purpose and nowadays, they are a standard part of commercial machines.

Directed nano-assembly of adaptive functional structures
