Improved bounded-strength decoupling schemes for local Hamiltonians
Adam D. Bookatz, Martin Roetteler, Pawel Wocjan
We address the task of switching off the Hamiltonian of a system by removing all internal and system-environment couplings. We propose dynamical decoupling schemes, that use only b…
Quantum Logic with Interacting Bosons in 1D
Yoav Lahini, Gregory R. Steinbrecher, Adam D. Bookatz +1
We present a scheme for implementing high-fidelity quantum logic gates using the quantum walk of a few interacting bosons on a one-dimensional lattice. The gate operation is carrie…
Error suppression in Hamiltonian based quantum computation using energy penalties
Adam D. Bookatz, Edward Farhi, Leo Zhou
We consider the use of quantum error detecting codes, together with energy penalties against leaving the codespace, as a method for suppressing environmentally induced errors in Ha…
Hamiltonian quantum simulation with bounded-strength controls
Adam D. Bookatz, Pawel Wocjan, Lorenza Viola
We propose dynamical control schemes for Hamiltonian simulation in many-body quantum systems that avoid instantaneous control operations and rely solely on realistic bounded-streng…
QMA-complete problems
Adam D. Bookatz
In this paper we give an overview of the quantum computational complexity class QMA and a description of known QMA-complete problems to date. Such problems are believed to be diffi…
Testing quantum expanders is co-QMA-complete
Adam D. Bookatz, Stephen P. Jordan, Yi-Kai Liu +1
A quantum expander is a unital quantum channel that is rapidly mixing, has only a few Kraus operators, and can be implemented efficiently on a quantum computer. We consider the pro…
The influence of polaron size on the conductivity of poly-DNA
Julia A. Berashevich, Adam D. Bookatz, Tapash Chakraborty
The velocity of polaron migration in the long poly-DNA chain (~40 base pairs) in an applied electric field has been studied within a polaron model. We found that the polaron veloci…
