Quantum Computational Method of Finding the Ground State Energy and Expectation Values
Sangchul Oh
We propose a new quantum computational way of obtaining a ground-state energy and expectation values of observables of interacting Hamiltonians. It is based on the combination of t…
Revealing anyonic features in a toric code quantum simulation
J. K. Pachos, W. Wieczorek, C. Schmid +3
Anyons are quasiparticles in two-dimensional systems that show statistical properties very distinct from those of bosons or fermions. While their isolated observation has not yet b…
Cavity cooling of translational and ro-vibrational motion of molecules: ab initio-based simulations for OH and NO
Markus Kowalewski, Giovanna Morigi, Pepijn W. H. Pinkse +1
We present detailed calculations at the basis of our recent proposal for simultaneous cooling the rotational, vibrational and external molecular degrees of freedom. In this method,…
Entanglement Distribution in Pure-State Quantum Networks
S. Perseguers, J. Wehr, A. Acin +2
We investigate entanglement distribution in pure-state quantum networks. We consider the case when non-maximally entangled two-qubit pure states are shared by neighboring nodes of…
On the distillation and purification of phase-diffused squeezed states
B. Hage, A. Franzen, J. DiGuglielmo +3
Recently it was discovered that non-Gaussian decoherence processes, such as phase-diffusion, can be counteracted by purification and distillation protocols that are solely built on…
Detuned Twin-Signal-Recycling for ultra-high precision interferometers
Andre Thuering, Roman Schnabel, Harald Lueck +1
We propose a new interferometer technique for high precision phase measurements such as those in gravitational wave detection. The technique utilizes a pair of optically coupled re…
