EDWIN B. FABILLAR Introduction Information carried by a quantum system has notoriously weird properties. Physicists and engineers are now learning how to put that weirdness to work. Quantum computers, which manipulate quantum states rather than classical bits, may someday be able to perform tasks that would be inconceivable with conventional digital technology. A particularly daunting [...]

EDMAR G. PANTOHAN This report is based on the very interesting researches of L. de Broglie on what he called “phase waves”. The advantages of the wave theory, The laws of motion and quantum condition can be derived from Hamiltonian principle. The discrepancy between the frequency of motion and frequency of emission disappears when the [...]

Karl Patrick S. Casas Consider a three-dimensional infinite cubical well The stationary states are and the allowed ground state energy is given by . The first excited state is triply degenerate, and we denote each degenerate state as Now, we introduce the perturbation   (shown in the figure above), We can get the first-order correction to [...]

Rommel J. Jagus Find the 2nd-order correction to the energies for the potential Solution: This is zero unless both m and n are odd in which case it is But So, Since For n=1 … For n=3 … Therefore if n is even if n is odd Source: Problem 6.4 A in “Introduction to Quantum [...]

Michael J. Jabines Quantum information science(QIS) is a new field of science and technology, combining and drawing on the disciplines of physical science, mathematics, computer science and engineering. Here, Quantum information processors exploit the quantum features of superposition and entanglement for application not possible in classical devices. It offers the potential for significant improvements in [...]
