Robust quantum gates for singlet-triplet spin qubits using composite pulses
Xin Wang, Lev S. Bishop, Edwin Barnes +2
We present a comprehensive theoretical treatment of SUPCODE, a method for generating dynamically corrected quantum gate operations, which are immune to random noise in the environm…
Robust Two-Qubit Gates for Exchange-Coupled Qubits
F. Setiawan, Hoi-Yin Hui, J. P. Kestner +2
We present composite pulse sequences that perform fault-tolerant two-qubit gate operations on exchange-only quantum dot spin qubits in various experimentally relevant geometries. W…
Ferromagnetic response of a "high-temperature" quantum antiferromagnet
Xin Wang, Rajdeep Sensarma, Sankar Das Sarma
We study the finite temperature antiferromagnetic phase of the ionic Hubbard model in the strongly interacting limit using quantum Monte Carlo based dynamical mean field theory. We…
Dynamically corrected gates for an exchange-only qubit
G. T. Hickman, Xin Wang, J. P. Kestner +1
We provide analytical composite pulse sequences that perform dynamical decoupling concurrently with arbitrary rotations for a qubit coded in the spin state of a triple quantum dot.…
Noise-resistant control for a spin qubit array
J. P. Kestner, Xin Wang, Lev S. Bishop +2
We develop a systematic method of performing corrected gate operations on an array of exchange-coupled singlet-triplet qubits in the presence of both fluctuating nuclear Overhauser…
