Generalised fractional Rabi problem
Alexander Lopez, Sébastien Fumeron, Malte Henkel +2
Fractional quantum dynamics provides a natural framework to capture nonlocal temporal behavior and memory effects in quantum systems. In this work, we analyze the physical conseque…
Real-Space Chemistry on Quantum Computers: A Fault-Tolerant Algorithm with Adaptive Grids and Transcorrelated Extension
César Feniou, Christopher Cherfan, Julien Zylberman +3
First-quantized, real-space formulations of quantum chemistry on quantum computers are appealing: qubit count scales logarithmically with spatial resolution, and Coulomb operators…
Quantum Circuits for the Metropolis-Hastings Algorithm
Baptiste Claudon, Pablo Rodenas-Ruiz, Jean-Philip Piquemal +1
Szegedy's quantization of a reversible Markov chain provides a quantum walk whose spectral gap is quadratically larger than that of the classical walk. Quantum computers are theref…
Quantum Speedup for Nonreversible Markov Chains
Baptiste Claudon, Jean-Philip Piquemal, Pierre Monmarché
Quantum algorithms can potentially solve a handful of problems more efficiently than their classical counterparts. In that context, it has been discussed that Markov chains problem…
Non-Iterative Disentangled Unitary Coupled-Cluster based on Lie-algebraic structure
Mohammad Haidar, Olivier Adjoua, Siwar Baddredine +2
Due to their non-iterative nature, fixed Unitary Coupled-Cluster (UCC) ansätze are attractive for performing quantum chemistry Variational Quantum Eigensolver (VQE) computations as…
Polylogarithmic-depth controlled-NOT gates without ancilla qubits
Baptiste Claudon, Julien Zylberman, César Feniou +3
Controlled operations are fundamental building blocks of quantum algorithms. Decomposing -control-NOT gates () into arbitrary single-qubit and CNOT gates, is a crucial b…
Sparse Quantum State Preparation for Strongly Correlated Systems
C. Feniou, O. Adjoua, B. Claudon +3
Quantum Computing allows, in principle, the encoding of the exponentially scaling many-electron wave function onto a linearly scaling qubit register, offering a promising solution…
Greedy Gradient-free Adaptive Variational Quantum Algorithms on a Noisy Intermediate Scale Quantum Computer
César Feniou, Muhammad Hassan, Baptiste Claudon +4
Hybrid quantum-classical adaptive Variational Quantum Eigensolvers (VQE) hold the potential to outperform classical computing for simulating many-body quantum systems. However, pra…
Overlap-ADAPT-VQE: Practical Quantum Chemistry on Quantum Computers via Overlap-Guided Compact Ansätze
César Feniou, Muhammad Hassan, Diata Traoré +3
ADAPT-VQE is a robust algorithm for hybrid quantum-classical simulations of quantum chemical systems on near-term quantum computers. While its iterative process systematically reac…
Open Source Variational Quantum Eigensolver Extension of the Quantum Learning Machine (QLM) for Quantum Chemistry
Mohammad Haidar, Marko J. Rančić, Thomas Ayral +2
Quantum Chemistry (QC) is one of the most promising applications of Quantum Computing. However, present quantum processing units (QPUs) are still subject to large errors. Therefore…
Calculating the ground state energy of benzene under spatial deformations with noisy quantum computing
Wassil Sennane, Jean-Philip Piquemal, Marko J. Rančić
In this manuscript, we calculate the ground state energy of benzene under spatial deformations by using the variational quantum eigensolver (VQE). The primary goal of the study is…
Non-linear Fano Interferences in Open Quantum Systems: an Exactly Solvable Model
Daniel Finkelstein-Shapiro, Monica Calatayud, Osman Atabek +2
We obtain an explicit solution for the stationary state populations of a dissipative Fano model, where a discrete excited state is coupled to a continumm set of states; both excite…
Fano-Liouville Spectral Signatures in Open Quantum Systems
Daniel Finkelstein-Shapiro, Ines Urdaneta, Monica Calatayud +3
The scattering amplitude from a set of discrete states coupled to a continuum became known as the Fano profile, characteristic for its asymmetric lineshape and originally investiga…
Simple Glass Models and their Quantum Annealing
Thomas Jorg, Florent Krzakala, Jorge Kurchan +1
We study first order quantum phase transitions in mean-field spin glasses. We solve the quantum Random Energy Model using elementary methods and show that at the transition the eig…
