The tunneling probability for the birth of a closed (D+ 1)-dimensional Friedmann-Lemaitre-Robertson-Walker space-time is calculated, and two particular cases are distinguished: (1) In the interpretation of parallel universes, we find that there is no preferred number of spatial dimensions. Then,...
Tags Mechanical Probability Quantum Tunneling Sep 21, 2012 #1 Demon117 162 1 I recently took an exam in which the professor asked the following question: Suppose an object of mass 2 grams were incident on a rectangular barrier of height 20 cm and width 2.0 cm. What is the probability th...
Quantum tunneling is a phenomenon where an electron is able to phase through a barrier and move to the other side. It is a quantum phenomenon that occurs when particles move through a barrier that, according to the theories of classical physics, should be impossible to pass through. When an ...
We formulate and analyze a double-slit proposal for quantum annealing, which involves observing the probability of finding a two-level system (TLS) undergoing evolution from a transverse to a longitudinal field in the ground state at the final timetf. We demonstrate that for annealing schedules in...
(strong coupling); ∼2–10nm are considered as an intermediate coupling range; at longer distance the probability for efficient FRET EET is extremely low (week coupling). An exciton that is not transferred successfully will eventually decay to the ground state through fluorescence or heat. Decay...

However, as already mentioned, the final state of each qubit on which the result of the calculation is read has to be determined with a very high probability and therefore be very close to 0 or 1. Typical problems of interest are those for which classical algorithms’ running time depends ...
3c). We can thus assume that the charge accumulation on the surface of the electrodes is equal on average during the tunneling event: Q^L=Q^R=Q^ with ⟨Q^⟩=e/2. The continuity equation dQ^/dt = I^L−I^T = I^T+I^R then implies I^T = (I^L−I^R)/2...
Tunneling Phenomena Potential Barriers. The first three particle-in-a- box wave functions are shown. For which wave function is the probability of finding the particle near x = L/2 the smallest? 1 Chapter 40 Quantum Mechanics April 6,8 Wave functions and Schrödinger equation 40.1 Wave ...
These two descriptions are linked through Schrödinger's equation. For each energy state there is an associated wavefunction which determines the spatial probability distribution of electrons in the state. Consequently, a change in quantum state implies a change in spatial distribution and energy of ...
