Conditions allowing error correction in driven qubits
Robert E. Throckmorton, S. Das Sarma
We consider a qubit that is driven along its logical axis, with noise along the axis in the driving field proportional to some function , as well as noise along t…
Plasmon-pole approximation for many-body-effects in extrinsic graphene
E. H. Hwang, Robert E. Throckmorton, S. Das Sarma
We develop the plasmon-pole approximation (PPA) theory for calculating the carrier self-energy of extrinsic graphene as a function of doping density within analytical approximation…
Failure of Kohn's theorem and the apparent failure of the -sum rule in intrinsic Dirac-Weyl materials in the presence of a filled Fermi sea
Robert E. Throckmorton, S. Das Sarma
Kohn's theorem and the -sum rule are powerful theorems, the first applying to translationally invariant single-band electronic systems with parabolic electronic dispersion relat…
Error correction for gate operations in systems of exchange-coupled singlet-triplet qubits in double quantum dots
Donovan Buterakos, Robert E. Throckmorton, S. Das Sarma
We present a scheme for correcting for crosstalk- and noise-induced errors in exchange-coupled singlet-triplet semiconductor double quantum dot qubits. While exchange coupling allo…
