Gate-efficient simulation of molecular eigenstates on a quantum computer
Marc Ganzhorn, Daniel J. Egger, Panagiotis Kl. Barkoutsos +8
A key requirement to perform simulations of large quantum systems on near-term quantum hardware is the design of quantum algorithms with short circuit depth that finish within the…
Quantum hardware simulating four-dimensional inelastic neutron scattering
A. Chiesa, F. Tacchino, M. Grossi +4
Magnetic molecules, modelled as finite-size spin systems, are test-beds for quantum phenomena and could constitute key elements in future spintronics devices, long-lasting nanoscal…
Local control theory for superconducting qubits
M. Malis, P. Kl. Barkoutsos, M. Ganzhorn +4
In this work, we develop a method to design control pulses for fixed-frequency superconducting qubits coupled via tunable couplers based on local control theory, an approach common…
Quantum algorithms for electronic structure calculations: particle/hole Hamiltonian and optimized wavefunction expansions
Panagiotis Kl. Barkoutsos, Jerome F. Gonthier, Igor Sokolov +9
In this work we investigate methods to improve the efficiency and scalability of quantum algorithms for quantum chemistry applications. We propose a transformation of the electroni…
Entanglement generation in superconducting qubits using holonomic operations
Daniel J. Egger, Marc Ganzhorn, Gian Salis +6
We investigate a non-adiabatic holonomic operation that enables us to entangle two fixed-frequency superconducting transmon qubits attached to a common bus resonator. Two coherent…
