It has previously been shown that probabilistic quantum logic operations can be performed using linear optical elements, additional photons (ancilla), and post-selection based on the output of single-photon detectors. Here we describe the operation of several quantum logic operations of an elementary nature, including a quantum parity check and a quantum encoder, and we show how they can be com...

By coating a thin layer of photosensitive polymer such as poly3-octylthiophene-2,5-diyl (P3OT), the Carbon Nanotube Field Effect Transistor (CNTFET) provides an optical gating phenomenon [1]. It is called Optical-Gated CNTFET (OG-CNTFET or OGCNTFET). Compared to the conventional CNTFET, the OG-CNTFET reveals a right hand shift of the drain current vs. gate bias voltage. If this device is under ...
