It’s often useful to have a private conversation within a public world. What role can quantum cryptography play in keeping conversations private? Sometimes described as providing “unconditional security guaranteed by the laws of quantum physics,” its security implications are both tantalizing and surprisingly elusive. This talk introduces quantum cryptography and describes the speaker’s experience creating several types of quantum cryptography equipment, within the broader context of mainstream cryptography and secure communications.

This lecture examines the implications of paradigm shifts in the different disciplines of sociology and physics.
In this three part lecture mini-course Roee Ozeri will review the basic building blocks of quantum information processing with cold-trapped atomic ions.
The main focus will be on methods to implement single-qubit rotations and two-qubit entangling gates, which form a universal set of quantum gates. Different ion-qubit choices and their respective gate implementations will be described.

Public lecture
The quantum laws governing atoms and other tiny objects seem to defy common sense, and information encoded in quantum systems has weird properties that baffle our feeble human minds.

Superconducting qubits based on Josephson junctions are a promising
platform for quantum computation, reaching quality factors of over one
million. Such high quality factors enable the investigation of
decoherence mechanisms with high accuracy. An intrinsic decoherence
process originates from the coupling between the qubit degree of freedom
and the quasiparticles that tunnel across Josephson junctions. In this
talk I will review the general theory of quasiparticle effects, valid
