We give a quantum information-theoretic description of an ideal propagating cw laser field and reinterpret typical quantum-optical experiments in light of this.

We introduce a primitive for quantum cryptography that we term ``state targeting.{''} We show that increasing one's probability of success in this task above a minimum amount implies an unavoidable

Using golden coordinates we have successfully isolated superconductors with T sub c > 10K into three small volumes in elemental configuration space.

Parametric devices based on four-wave mixing processes in fibers can amplify, frequency convert, phase conjugate, regenerate, sample and delay signals in conventional communication systems.

Rings fabricated from one dimensional GaAs heterostructures display a suppression of the Aharonov-Bohm effect at magnetic fields of about .75-1.0 Tesla.

High mobility two-dimensional electron systems in GaN/AlGaN heterostructures have been realized by plasma assisted molecular beam epitaxy on GaN templates.

Narrow MOSFET channels are investigated as quasi-one-dimensional electron systems containing a small number of electrons.
