Invited Speaker / Conférencier invité

Quantum communication allows the provably secure distribution of cryptographic keys, and the teleportation of quantum states between distant particles. Applications of these two key concepts of quantum information processing generally require sender and receiver to be at distant locations.
I will discuss our recent advances in quantum key distribution (QKD) and quantum teleportation using the...

1680. Thermalization by Rapid Repeated Interactions

CLOSED - Oral (Student, Not in Competition) / Orale (Étudiant(e), pas dans la compétition)

We investigate the open dynamics of a quantum system undergoing short discrete repeated interactions. We assume the joint dynamics of the system and the ancilla are unitary and the interaction is of brief duration $\delta t$. We then take the unique Markovian interpolation between the discrete post-interaction states and find its Master Equation. To zeroth order in $\delta t$ we find the...

1675. Entanglement Harvesting with Inertially Moving Detectors

Theoretical Physics / Physique théorique (DTP-DPT)

CLOSED - Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)

We analyze the entanglement harvested from a quantum field through local interactions of a pair of identical Unruh-DeWitt detectors that are moving with relative constant velocity. These detectors are taken to be point-like and have Gaussian switching. For detectors moving in opposite directions we find that the entanglement harvested has a complicated dependence on the detectors’...

1575. Airborne Demonstration of a Quantum Key Distribution Receiver Payload

Demonstrations of quantum key distribution (QKD) with moving platforms are important to prove the viability of future satellite implementations. Thus far, however, demonstrations of QKD to aircraft have operated exclusively in the downlink configuration where the quantum source and transmitter are placed on the airborne platform. While this approach ultimately has the potential for higher key...
