The quantum mechanical phenomenon of having a system of particles be in a superposition of several states at once allows a quantum computer to perform an exponential number of computations in a single step. The results, however, remain in a superimposed state and c ...

... and also adds suitable potentials (which are necessary to keep the gap from closing.) Thus one relates incompressible states with different quantum statistics in different background magnetic fields. At ii l/(2m + 1) one has incompressible fermion states, suitable for describing ordinary electrons, ...

Cloaking of Matter Waves
... Cloaking of electromagnetic waves is possible due to time invariant coordinate transformation of the governing Maxwell’s equations. Such invariant transformations map a particular region in free space to a spatial domain with position dependent and anisotropic material parameters (such as permeabili ...

In this case measurements project the system to Bloch states corresponding to the measured spin components. ...

Basic Notions of Entropy and Entanglement
... On the other hand, if the indicator is “irreversible” and does not automatically return to its initial setting, we will not get back to the initial state, and we cannot literally repeat the cycle. In this situation, if we have a store of indicators, their values, after use, will constitute a memory. ...

Is the quantum mechanical description of physical reality complete

The above channel construction scheme relies on three key components: (1) ability to apply a certain class of unitary gates (recall that we engineer only the left half of the unitary) on the system and ancilla combined system; (2) QND readout of the ancilla qubit; (3) adaptive control of all unitary ...
