Efficient Block Encodings for Ensembles of Molecular Hamiltonians
Cristian L. Cortes, Andrew J. Jenkins, William Pol +8
Accurately characterizing molecular properties and reactivity often requires electronic-structure calculations across an ensemble of molecular geometries. Quantum algorithms that p…
Compiling the 2D Fermi-Hubbard ground-state energy estimation algorithm for active volume quantum architectures
Harriet Apel, Athena Caesura, Carys Harvey +11
As quantum computing enters the early fault-tolerant era, circuit compilation choices will increasingly depend on details of the underlying architecture rather than solely optimizi…
Reducing quantum resources for observable estimation with window-assisted coherent QPE
Harriet Apel, Cristian L. Cortes, Jessica Lemieux +1
Quantum Phase Estimation (QPE) routines are known to fail probabilistically even with perfect gates and input states. This effect stems from an incompatibility of finite-sized quan…
Faster quantum chemistry simulations on a quantum computer with improved tensor factorization and active volume compilation
Athena Caesura, Cristian L. Cortes, William Pol +8
Electronic structure calculations of molecular systems are among the most promising applications for fault-tolerant quantum computing (FTQC) in quantum chemistry and drug design. H…
Fault-tolerant quantum algorithm for symmetry-adapted perturbation theory
Cristian L. Cortes, Matthias Loipersberger, Robert M. Parrish +9
The efficient computation of observables beyond the total energy is a key challenge and opportunity for fault-tolerant quantum computing approaches in quantum chemistry. Here we co…
Simulating quantum error mitigation in fermionic encodings
Riley W. Chien, Kanav Setia, Xavier Bonet-Monroig +2
The most scalable proposed methods of simulating lattice fermions on noisy quantum computers employ encodings that eliminate nonlocal operators using a constant factor more qubits…
Fault-tolerant quantum computation of molecular observables
Mark Steudtner, Sam Morley-Short, William Pol +8
Over the past three decades significant reductions have been made to the cost of estimating ground-state energies of molecular Hamiltonians with quantum computers. However, compara…
Randomizing multi-product formulas for Hamiltonian simulation
Paul K. Faehrmann, Mark Steudtner, Richard Kueng +2
Quantum simulation, the simulation of quantum processes on quantum computers, suggests a path forward for the efficient simulation of problems in condensed-matter physics, quantum…
Quantum simulation by qubitization without Toffoli gates
Mark Steudtner, Stephanie Wehner
Qubitization is a modern approach to estimate Hamiltonian eigenvalues without simulating its time evolution. While in this way approximation errors are avoided, its resource and ga…
Quantum codes for quantum simulation of Fermions on a square lattice of qubits
Mark Steudtner, Stephanie Wehner
Quantum simulation of fermionic systems is a promising application of quantum computers, but in order to program them, we need to map fermionic states and operators to qubit states…
Quantum error correction in crossbar architectures
Jonas Helsen, Mark Steudtner, Menno Veldhorst +1
A central challenge for the scaling of quantum computing systems is the need to control all qubits in the system without a large overhead. A solution for this problem in classical…
Lowering qubit requirements for quantum simulations of fermionic systems
Mark Steudtner, Stephanie Wehner
The mapping of fermionic states onto qubit states, as well as the mapping of fermionic Hamiltonian into quantum gates enables us to simulate electronic systems with a quantum compu…
A Crossbar Network for Silicon Quantum Dot Qubits
R. Li, L. Petit, D. P. Franke +10
The spin states of single electrons in gate-defined quantum dots satisfy crucial requirements for a practical quantum computer. These include extremely long coherence times, high-f…

Jarrod R. McClean, Kevin J. Sung, Ian D. Kivlichan +32
Quantum simulation of chemistry and materials is predicted to be an important application for both near-term and fault-tolerant quantum devices. However, at present, developing and…
Anderson localization and momentum-space entanglement
Eric C. Andrade, Mark Steudtner, Matthias Vojta
We consider Anderson localization and the associated metal-insulator transition for non-interacting fermions in D = 1, 2 space dimensions in the presence of spatially correlated on…
