Properties of higher-order Trotter formulas
... Higher-order Trotter formulas provide a very general and systematic way to derive discrete approximations of path integrals for quantum mechanical or quantum statistical systems. These discretizations converge more rapidly while being only slightly more complicated than the usual low-order formulati ...

... When classical physics treated open systems, it was tacitly assumed (as an article of faith) that, by suitable enlargement of the system, it could always be included in closed system of a deterministic type. … The contrast between open and closed should not be taken as identical with the contrast be ...

Direct Characterization of Quantum Dynamics
... An additional feature of DCQD is that all the required ensemble measurements, for measuring the expectation values of the stabilizer and normalizer operators, can also be performed in a temporal sequence on the same pair of qubits with only one Bell-state generation. This is because at the end of ea ...

Attractive photons in a quantum nonlinear medium
... We measure the dynamical evolution of the two-photon wavefunction using time-resolved quantum state tomography, and demonstrate a conditional phase shift8 exceeding one radian, resulting in polarization-entangled photon pairs. Particular applications of this technique include all-optical switching, ...
