Reducing entanglement with a Hamiltonian derived Clifford transformation
James Brown, Erika Lloyd, Alexandre Fleury +2
Recently (Physica Scripta, 100(10):105401, 2025), an algorithm was introduced that deterministically generates a Clifford transformation from the Qubit Coupled Cluster (QCC) algori…
Evolving Quantum Error-Correcting Encodings for Molecular Simulation
Kenny Heitritter, James Brown, Tarini Hardikar
Useful quantum algorithms require many coupled discrete design choices. We study LLM-driven evolutionary program synthesis -- a language model edits a program, an external verifier…
Mid-Circuit Measurements for Clifford Noise Reduction in Hamiltonian Simulations
James Brown, Jason Iaconis, Yuri Alexeev +6
Quantum simulation of fermionic Hamiltonians is a leading application of quantum computing, but accurate execution on present-day hardware is limited by error accumulation in deep…
Efficient and Noise-Resilient Molecular Quantum Simulation with the Generalized Superfast Encoding
James Brown, Tarini S Hardikar, Kenny Heitritter +1
Simulating molecular systems on quantum computers requires efficient mappings from Fermionic operators to qubit operators. Traditional mappings such as Jordan-Wigner or Bravyi-Kita…
Quantum Reservoir Computing for Corrosion Prediction in Aerospace: A Hybrid Approach for Enhanced Material Degradation Forecasting
Akshat Tandon, James Brown, Kenny Heitritter +5
The prediction of material degradation is an important problem to solve in many industries. Environmental conditions, such as humidity and temperature, are important drivers of deg…
