Quantum superposition of molecules beyond 25 kDa

Nature Physics, 2019
Matter-wave interference experiments provide a direct confirmation of the quantum superposition principle, a hallmark of quantum theory, and thereby constrain possible modifications to quantum mechanics(1).

Quantum superpositions generated by quantum nondemolition measurements

Physical Review A, 1990
We analyze a quantum nondemolition measurement scheme similar to that advocated by Song, Caves, and Yurke [Phys. Rev. A 41, 5261 (1990)] for generating superpositions of macroscopically distinct quantum states, but with the parametric amplifier and the back-action evader interchanged.

Synthesis of Quantum Superpositions by Quantum Computation

Physical Review Letters, 2000
The quantum search algorithm can be looked at as a technique for synthesizing a particular kind of superposition-one whose amplitude is concentrated in a single basis state. This basis state is defined by a binary function f(&xmacr;) that is nonzero in this desired basis state and zero everywhere else. This paper extends the quantum search algorithm to

What is a Quantum Superposition?

2020
Henry has successfully tested the Split button of his quantum suit that enables a quantum object to be in several places at the same time. This bizarre phenomenon is explained by the superposition principle, which reflects Henry’s wavelike properties. Yet Henry remains a single entity as he splits into two superposed versions.

Ψ Superposition and Quantnm Rules

American Journal of Physics, 1956
The superposition rule for probability amplitudes ψ is not a separate ad hoc assumption of a physical character but is a formal consequence of the arrangement of the states of a system in sets of mutually orthogonal states linked by probabilities of transition.

Superposition and quantum mechanics

International Journal of Theoretical Physics, 1986
The author claims to have found those physical assumptions from which quantum theory can be deduced. However, his mathematical objects are defined and described in such a non-mathematical language that it is not at all easy to make sense of the author's thesis.

Computation And Quantum Superposition

Workshop on Physics and Computation, 2005
We review recent work and some new results on the role of quantum superpositions in providing new modes of computation, not available to classical computers. For certain problems, these new modes can provide an exponential reduction in complexity over any classical computer demonstrating the importance of quantum processes for issues in complexity ...

Quantum Interference and Superposition

2014
Apart from technological applications, interference experiments with massive particles in ample range of masses (electrons, neutrons, atoms, small clusters, organic molecules, or even Bose-Einstein condensates) have attracted a lot of attention in the last years due to their fundamental aspect as exploring tools of the limits of quantum mechanics.

Quantum Superposition and Entanglement

2020
In this chapter, the notion of quantum superposition of states is introduced through the example of a polarized photon. This brings out the novel feature that the state of the system depends on how the experiment is set up. The paradoxical consequences of quantum superposition, such as a cat can be simultaneously dead and alive, are also discussed ...
