Conditional quantum-state transformation at a beam splitter
J. Clausen, M. Dakna, L. Knoll +1
Using conditional measurement on a beam splitter, we study the transformation of the quantum state of the signal mode within the concept of two-port non-unitary transformation. All…
Generation of arbitrary quantum states of traveling fields
M. Dakna, J. Clausen, L. Knoll +1
We show that any single-mode quantum state can be generated from the vacuum by alternate application of the coherent displacement operator and the creation operator. We propose an…
Generating and monitoring Schrödinger cats in conditional measurement on a beam splitter
M. Dakna, J. Clausen, L. Knoll +1
Preparation of Schrödinger-cat-like states via conditional output measurement on a beam splitter is studied. In the scheme, a mode prepared in a squeezed vacuum is mixed with a mod…
Quantum state engineering using conditional measurement on a beam splitter
M. Dakna, L. Knoll, D. -G. Welsch
State preparation via conditional output measurement on a beam splitter is studied, assuming the signal mode is mixed with a mode prepared in a Fock state and photon numbers are me…
Homodyne measurement of exponential phase moments for quantum-phase reconstruction
M. Dakna, G. Breitenbach, J. Mlynek +3
We directly sample the exponential moments of the canonical phase for various quantum states from the homodyne output. The method enables us to study the phase properties experimen…
