Assessing requirements to scale to practical quantum advantage
Michael E. Beverland, Prakash Murali, Matthias Troyer +7
While quantum computers promise to solve some scientifically and commercially valuable problems thought intractable for classical machines, delivering on this promise will require…
Halving the cost of quantum multiplexed rotations
Guang Hao Low
We improve the number of gates needed for a -bit approximation of a multiplexed quantum gate with controls applying single-qubit arbitrary phase rotations from $4n b…
A Variational Quantum Algorithm for Preparing Quantum Gibbs States
Anirban N. Chowdhury, Guang Hao Low, Nathan Wiebe
Preparation of Gibbs distributions is an important task for quantum computation. It is a necessary first step in some types of quantum simulations and further is essential for quan…
Quantum simulations of excited states with active-space downfolded Hamiltonians
Nicholas P. Bauman, Guang Hao Low, Karol Kowalski
Many-body techniques based on the double unitary coupled cluster ansatz (DUCC) can be used to downfold electronic Hamiltonians into low-dimensional active spaces. It can be shown t…
Well-conditioned multiproduct Hamiltonian simulation
Guang Hao Low, Vadym Kliuchnikov, Nathan Wiebe
Product formula approximations of the time-evolution operator on quantum computers are of great interest due to their simplicity, and good scaling with system size by exploiting co…
Q# and NWChem: Tools for Scalable Quantum Chemistry on Quantum Computers
Guang Hao Low, Nicholas P. Bauman, Christopher E. Granade +9
Fault-tolerant quantum computation promises to solve outstanding problems in quantum chemistry within the next decade. Realizing this promise requires scalable tools that allow use…
