Optimal lossy quantum interferometry in phase space
Andrei B. Klimov, Marcin Zwierz, Sascha Wallentowitz +2
We analyse the phase space representation of the optimal measurement of a phase shift in an interferometer with equal photon loss in both its arms. In the local phase estimation sc…
Surmounting intrinsic quantum-measurement uncertainties in Gaussian-state tomography with quadrature squeezing
Jaroslav Rehacek, Yong Siah Teo, Zdenek Hradil +1
We reveal that quadrature squeezing can result in significantly better quantum-estimation performance with quantum heterodyne detection (of H. P. Yuen and J. H. Shapiro) as compare…
Emergence of metastable pointer states basis in non-Markovian quantum dynamics
F. Lastra, C. E. López, S. A. Reyes +1
We investigate the dynamics of classical and quantum correlations between two qubits. Each qubit is implemented by a pair of phosphorous impurities embedded in a silicon substrate.…
Phonon-induced entanglement dynamics of two donor-based charge quantum bits
F. Lastra, S. A. Reyes, S. Wallentowitz
The entanglement dynamics of a pair of donor-based charge qubits is obtained in analytical form. The disentanglement is induced by off resonant scattering of acoustical phonons in…
Analytical model of non-Markovian decoherence in donor-based charge quantum bits
F Lastra, S Reyes, S Wallentowitz
We develop an analytical model for describing the dynamics of a donor-based charge quantum bit (qubit). As a result, the quantum decoherence of the qubit is analytically obtained a…
Dynamics of entanglement between two free atoms with quantized motion
F. Lastra, S. Wallentowitz
The electronic entanglement between two free atoms initially at rest is obtained including the effects of photon recoil, for the case when quantum dispersion can be neglected durin…
