On the Einstein-Podolsky-Rosen paradox
... With the example advocated by Bohm and Aharonov [6], the EPR argument is the following. Consider a pair of spin one-half particles formed somehow in the singlet spin state and moving freely in opposite directions. Measurements can be made, say by Stern-Gerlach magnets, on selected components of the ...

Quantum Memories at Room-Temperature Supervisors: Dr Dylan
... in our lambda Raman quantum memory. This will be demonstration of a new protocol: a quantum Zeno noise suppression technique to kill a noise-process prohibits quantum operation, a process known as four-wave-mixing. We will suppress two-mode-squeezing via incoherent Hamiltonian engineering. This work ...

QUANTUM DOTS
... In the case of the high barrier potential the tunnelling is forbidden between dots (no evolution in time). In the low barrier potential spins will be subject to a transient Heisenberg coupling (Hubbard model). The equation obtained with this model gives a good description of a quantum dot system if ...

... introduce them by giving a rough overview over the historical development. Historically, Bethe's 1931 work on the isotropic case (gx = gy = gz), known as the XXX model, had a major impact and was the starting point for many of the subsequent developments in this area. He made an "ansatz" for the sta ...

Does the Everyday World Really Obey Quantum Mechanics?
... Figure 1 Erwin Schrödinger (left) and Niels Bohr. Bohr claimed that a momentum kick, imparted by any measurement of particle position, could explain the disappearance of quantum interference in ‘two-slit’ experiments. A new experiment1 shows that this effect is too small, and the disappearance must ...

The only information that was important was the size of the orbit, which was described by the n quantum number. Schrödinger's model allowed the electron to o ...

We show that under usual experimental conditions ultracold atomic gases actually show strong deviation from Einstein's saturation picture, but saturation ...
