Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Invited Speaker / Conférencier(ère) invité(e)

We will describe the principals of Rydberg atom-based radio frequency (RF) sensors. The introduction will be followed by a descriptions of recent advances that have been made at Quantum Valley Ideas Laboratories. We will describe experiments where vapor cells are engineered for low background electric fields and enhancement of the RF field. These improvements lead to better sensitivity and...

972. It’s Been a Hot Second: Atomic clocks, timescales, and the redefinition of the SI second

Invited Speaker / Conférencier(ère) invité(e)

How do we know what time it is—and how can we ensure that a second measured today will be the same tomorrow, or on the other side of the world? Modern timekeeping answers these questions by tying time to the fundamental properties of atoms, achieving a level of precision that underpins both advanced technologies and fundamental physics.
In this talk, I will describe how atomic clocks are used...

976. Building an integrated telecom-wavelength quantum platform with artificial atoms

Nir Rotenberg (Queen's University)

Atomic, Molecular and Optical Physics, Canada / Physique atomique, moléculaire et photonique, Canada (DAMOPC-DPAMPC)

Invited Speaker / Conférencier(ère) invité(e)

Scaling up light-based quantum devices for communications requires a platform capable of creating and processing telecommunication wavelength quantum light states. In this talk, I will introduce a quantum dot-based platform that our group has been developing together with NRC. The quantum dots, which act like artificial semiconductor atoms, are grown in a unique way; I will show how, already...
