Isotropic Landau levels of relativistic and non-relativistic fermions in 3D flat
Abstract: We generalize the two-dimensional Landau level problem to three dimensions and above for both the relativistic and non-relativistic cases. For the 3D case filled with fermions, the systems ...

Quantum Journal Club: Efficient Experimental Estimation of Fidelity of Linear Op
Abstract: We propose an efficiently measurable lower bound on quantum process fidelity of N-qubit controlled-Z gates. This bound is determined by average output state fidelities for N partially conju...

Quantum Journal Club: Condensation of Pairs of Fermionic Atoms near a Feshbach
Abstract: We have observed Bose-Einstein condensation of pairs of fermionic atoms in an ultracold 6Li gas at magnetic fields above a Feshbach resonance, where no stable 6Li2 molecules would exist in ...

Quantum Journal Club: Experimental Protection of Two-Qubit Quantum Gates against Environmental Noise by Dynamical Decoupling
Abstract: Hybrid systems consisting of different types of qubits are promising for building quantum computers if they combine useful properties of their constituent qubits. However, they also pose ad...
