In this paper we demonstrate that a quantum-like interference pattern could appear as a statistical effect of interference of deterministic particles, i.e. particles that have trajectories and obey deterministic dynamical equations, if one introduces a discrete time. The nature of the resulting interference picture does not follow from the geometry of force field, but is strongly attached to th...

The origin of quantum interference characteristic of bound nonlinear systems is investigated within the Bohmian formulation of time-dependent quantum mechanics. By contrast to time-dependent semiclassical theory, whereby interference is a consequence of phase mismatch between distinct classical trajectories, the Bohmian, fully quantum mechanical expression for expectation values has a quasiclas...

We propose a computing model, the Two-Way Optical Interference Automata (2OIA), that makes use of the phenomenon of optical interference. We introduce this model to investigate the increase in power, in terms of language recognition, of a classical Deter-ministic Finite Automaton (DFA) when endowed with the facility of optical interference.] wherein the classical DFA is augmented with a quantum...

The identification of phenomena able to pinpoint quantum interference is attracting large interest. Indeed, a generalization of the Hong-Ou-Mandel effect valid for any number of photons and optical modes would represent an important leap ahead both from a fundamental perspective and for practical applications, such as certification of photonic quantum devices, whose computational speedup is exp...

The ability to control dynamics of quantum states by optical interference, and subsequent electrical read-out, is crucial for solid state quantum technologies. Ramsey interference has been successfully observed for spins in silicon and nitrogen vacancy centres in diamond, and for orbital motion in InAs quantum dots. Here we demonstrate terahertz optical excitation, manipulation and destruction ...

The famous gedanken experiments of quantum mechanics have historically played crucial roles in trying to understand quantum mechanics and in developing the Copenhagen interpretation. They are re-examined here from the perspective of standard quantum mechanics, without a mix of any ontological interpretation. It is shown that, in most of these gedanken experiments, entanglement plays a crucial r...

Interference experiments provide a simple yet powerful tool to unravel fundamental features of quantum physics. Here we engineer an RF-driven, time-dependent bilinear coupling that can be tuned to implement a robust 50:50 beamsplitter between stationary states stored in two superconducting cavities in a three-dimensional architecture. With this, we realize high contrast Hong-OuMandel (HOM) inte...

Polarization entangled photon pair source is widely used in many quantum information processing applications such as teleportation, quantum communications, quantum computation and high precision quantum metrology. We report on the generation of a continuous-wave pumped 1550 nm polarization entangled photon pair source at telecom wavelength using a type-II periodically poled KTiOPO(4) (PPKTP) cr...

Quantum interference is proposed as a tool to augment Quantum Computation. 1 Can quantum interference augment Quantum Computation? 1.1 The dilemma The power of quantum computing lies in the quantum ability to have a linear superposition of all possible states (Hadamard spread), so that one could produce the following, non-entangled, 3 qubit state (we ignore the normalizations throughout for sim...
