Electronic structure of rectangular quantum dots
... a hard-wall confinement has not been generalized into arbitrary rectangular shapes. However, experiments have been done on rectangular mesas of vertical dots by Austing et al.,17 who applied electron-beam lithography with etching techniques on a double-barrier heterostructure.18 They measured the ad ...

... gain, which is information beyond "eff ð!Þ. For loss-loss and gain-gain metamaterials the a and b add up to unity. Only in the case Ta ¼ Tb , as for a passive lossy metamaterial at room temperature, we then find that Neff reduces to the thermal distribution Nth . Thus our QOEM theory explains our ...

The fundamental reason for this goes beyond the classical description in terms of the wave formalism, it is rooted in quantum mechanics. Quantum ...

The Learnability of Quantum States
... Claim: For all awN, there’s a randomized protocol where Alice sends a+O(log N) bits and Merlin sends w bits Proof: Alice divides x into w-bit substrings. She then encodes each one with an error-correcting code, and sends Bob a random k along with the kth bit of each codeword. Merlin sends the subst ...
