Quantum versus Classical Annealing of Ising Spin Glasses
Bettina Heim, Troels F. Rønnow, Sergei V. Isakov +1
The strongest evidence for superiority of quantum annealing on spin glass problems has come from comparing simulated quantum annealing using quantum Monte Carlo (QMC) methods to si…
Atmospheric continuous-variable quantum communication
Bettina Heim, Christian Peuntinger, Nathan Killoran +4
We present a quantum communication experiment conducted over a point-to-point free-space link of 1.6 km in urban conditions. We study atmospheric influences on the capability of th…
Distribution of squeezed states through an atmospheric channel
Christian Peuntinger, Bettina Heim, Christian R. Müller +3
Continuous variable quantum states of light are used in quantum information protocols and quantum metrology and known to degrade with loss and added noise. We were able to show the…
