Search for Majorana Fermions in p-Type Semiconductor Thin Films and Nanowires
Abstract: Majorana fermions were envisioned by E. Majorana in 1935 to describe neutrinos. Majorana fermions are intriguing because they can be construed as their own anti-particles and follow non-Abe...

Quantum Journal Club: Coherent Ultrafast Measurement of Time-Bin Encoded Photons
Abstract: Time-bin encoding is a robust form of optical quantum information, especially for transmission in optical fibers. To readout the information, the separation of the time bins must be larger ...

Optically controlled phase gate for two spin qubits in coupled quantum dots
Abstract: We present a feasible scheme for performing an optically controlled phase gate between two conduction lectron spin qubits in adjacent self-assembled quantum dots. Interaction between the do...
