Preparation of Non-equilibrium Nuclear Spin States in Double Quantum Dots
M. Gullans, J. J. Krich, J. M. Taylor +2
We theoretically study the dynamic polarization of lattice nuclear spins in GaAs double quantum dots containing two electrons. In our prior work [Phys. Rev. Lett. 104, 226807 (2010…
A proposal to probe quantum non-locality of Majorana fermions in tunneling experiments
Jay D. Sau, Brian Swingle, Sumanta Tewari
Topological Majorana fermion (MF) quasiparticles have been recently suggested to exist in semiconductor quantum wires with proximity induced superconductivity and a Zeeman field. A…
Valley Degenerate 2D Electrons in the Lowest Landau Level
Tomasz M. Kott, Binhui Hu, S. H. Brown +1
We report low temperature magnetotransport measurements on a high mobility (μ=325,000 cm^2/V sec) 2D electron system on a H-terminated Si(111) surface. While low magnetic field dat…
Manipulating Topological Edge Spins in One-Dimensional Optical Lattice
Xiong-Jun Liu, Zheng-Xin Liu, Meng Cheng
We propose to observe and manipulate topological edge spins in 1D optical lattice based on currently available experimental platforms. Coupling the atomic spin states to a laser-in…
Simulating Capacitances to Silicon Quantum Dots: Breakdown of the Parallel Plate Capacitor Model
Ted Thorbeck, Akira Fujiwara, Neil M. Zimmerman
Many electrical applications of quantum dots rely on capacitively coupled gates; therefore, to make reliable devices we need those gate capacitances to be predictable and reproduci…
Fabrication and Electrical Characterization of Fully CMOS Si Single Electron Devices
P. J. Koppinen, M. D. Stewart, Neil M. Zimmerman
We present electrical data of silicon single electron devices fabricated with CMOS techniques and protocols. The easily tuned devices show clean Coulomb diamonds at T = 30 mK and c…
Manipulating Majorana Fermions in Quantum Nanowires with Broken Inversion Symmetry
Xiong-Jun Liu, Alejandro M. Lobos
We study a Majorana-carrying quantum wire, driven into a trivial phase by breaking the spatial inversion symmetry with a tilted external magnetic field. Interestingly, we predict t…
To close or not to close: the fate of the superconducting gap across the topological quantum phase transition in Majorana-carrying semiconductor nanowires
Tudor D. Stanescu, Sumanta Tewari, Jay D. Sau +1
We investigate theoretically the low energy physics of semiconductor Majorana wires in the vicinity of a magnetic field-driven topological quantum phase transition (TQPT). The loca…
Circuit Quantum Electrodynamics with a Spin Qubit
K. D. Petersson, L. W. McFaul, M. D. Schroer +4
Circuit quantum electrodynamics allows spatially separated superconducting qubits to interact via a "quantum bus", enabling two-qubit entanglement and the implementation of simple…
Topological minigap in quasi-one-dimensional spin-orbit-coupled semiconductor Majorana wires
Sumanta Tewari, T. D. Stanescu, J. D. Sau +1
The excitation gap above the Majorana fermion (MF) modes at the ends of 1D topological superconducting (TS) semiconductor wires scales with the bulk quasiparticle gap E_{qp}. This…
Zero bias conductance peak in Majorana wires made of semiconductor-superconductor hybrid structures
Chien-Hung Lin, Jay D. Sau, S. Das Sarma
Motivated by a recent experimental report[1] claiming the likely observation of the Majorana mode in a semiconductor-superconductor hybrid structure[2,3,4,5], we study theoreticall…
All-optical tuning of a quantum dot in a coupled cavity system
Ranojoy Bose, Tao Cai, Glenn. S. Solomon +1
We demonstrate a method of tuning a semiconductor quantum dot (QD) onto resonance with a cavity mode all-optically. We use a system comprised of two evanescently coupled cavities c…
Composite pulses for robust universal control of singlet-triplet qubits
Xin Wang, Lev S. Bishop, J. P. Kestner +3
Precise qubit manipulation is fundamental to quantum computing, yet experimental systems generally have stray coupling between the qubit and the environment, which hinders the nece…
Interplay of disorder and interaction in Majorana quantum wires
Alejandro M. Lobos, Roman M. Lutchyn, S. Das Sarma
We study the interplay between disorder and interaction in one-dimensional topological superconductors which carry localized Majorana zero-energy states. Using Abelian bosonization…
Determining the Location and Cause of Unintentional Quantum Dots in a Nanowire
Ted Thorbeck, Neil M. Zimmerman
We determine the locations of unintentional quantum dots (U-QDs) in a silicon nanowire with a precision of a few nanometers by comparing the capacitances to multiple gates with a c…
