Progress towards practical quantum variational algorithms
The preparation of quantum states using short quantum circuits is one of the most promising near-term applications of small quantum computers, especially if the circuit is short enough and the
Evidence for quantum annealing with more than one hundred qubits
Quantum annealing is expected to solve certain optimization problems more efficiently, but there are still open questions regarding the functioning of devices such as D-Wave One. A numerical and
LIQUi|>: A Software Design Architecture and Domain-Specific Language for Quantum Computing
Languages, compilers, and computer-aided design tools will be essential for scalable quantum computing, which promises an exponential leap in our ability to execute complex tasks. LIQUi|> is a
Defining and detecting quantum speedup
Here, it is shown how to define and measure quantum speedup and how to avoid pitfalls that might mask or fake such a speedup, and the subtle nature of the quantum speed up question is illustrated.
Elucidating reaction mechanisms on quantum computers
This work shows how quantum computers can be used to elucidate the reaction mechanism for biological nitrogen fixation in nitrogenase, by augmenting classical calculation of reaction mechanisms with reliable estimates for relative and activation energies that are beyond the reach of traditional methods.
Improving quantum algorithms for quantum chemistry
Improvements to the standard Trotter-Suzuki based algorithms used in the simulation of quantum chemistry on a quantum computer by modifying how Jordan-Wigner transformations are implemented to reduce their cost from linear or logarithmic in the number of orbitals to a constant.
Gate count estimates for performing quantum chemistry on small quantum computers
As quantum computing technology improves and quantum computers with a small but non-trivial number of N > 100 qubits appear feasible in the near future the question of possible applications of small
The Trotter step size required for accurate quantum simulation of quantum chemistry
This study presents an alternative simulation scheme and shows that it can sometimes outperform existing schemes, but that this possibility depends crucially on the details of the simulated molecule.
Hybrid quantum-classical approach to correlated materials
This work shows that by using a hybrid quantum-classical algorithm that incorporates the power of a small quantum computer into a framework of classical embedding algorithms, the electronic structure of complex correlated materials can be efficiently tackled using a quantum computer.
On the Chemical Basis of Trotter-Suzuki Errors in Quantum Chemistry Simulation
Although the simulation of quantum chemistry is one of the most anticipated applications of quantum computing, the scaling of known upper bounds on the complexity of these algorithms is daunting.
