Conditions for implementing projective measurements through continuous monitoring
Therese Karmstrand, Franco Nori, Clemens Gneiting
Projective measurements are foundational for quantum physics in general and quantum information tasks in particular. However, their direct implementation is often not warranted. He…

Superbunching from coherently driven atoms in a waveguide
Zeidan Zeidan, Therese Karmstrand, Maryam Khanahmadi +1
We investigate the scattered field from identical two-level atoms resonantly driven by a weak coherent field in a one-dimensional waveguide. For atoms separated by the drive wa…

Successive quasienergy collapse and breakdown of photon blockade in the few-emitter limit
T. Karmstrand, G. Johansson, R. Gutiérrez-Jáuregui
The emergent behavior that arises in many-body systems of increasing size follows universal laws that become apparent in order-to-disorder transitions. While this behavior has been…
