Stabilizer Statistical Mechanics: A Framework for Efficient Quantification and Classification of Magic States
William E. Salazar, Gaurav Saxena, Jack S. Baker +2
The partition function is statistical mechanics' answer to an exponentially large spectrum, distilling it into a single analytic object whose temperature dependence resolves the fu…
Designing quantum technologies with a quantum computer
Juan Naranjo, Thi Ha Kyaw, Gaurav Saxena +2
The paper presents a quantum‑computer‑aided framework for simulating solid‑state spin systems, using advanced qudit‑to‑qubit mappings and a selected quantum Krylov fast‑forwarding…
Efficient Quantum Circuits for Coherent Conversion Between General First- and Second-Quantized Many-Body Representations
Jack S. Baker, Gaurav Saxena, Thi Ha Kyaw
Quantum simulation at fixed particle number admits two equivalent descriptions, a first-quantized (particle) representation and a second-quantized (occupation-number) representatio…
Physics-Inspired Extrapolation for efficient error mitigation and hardware certification
Pablo DÃez-Valle, Gaurav Saxena, Jack S. Baker +2
Quantum error mitigation (QEM) is essential for the noisy intermediate-scale quantum era, and will remain relevant for early fault-tolerant quantum computers, where logical error r…
Error-Mitigation Enabled Multicomponent Quantum Simulations Beyond the Born-Oppenheimer Approximation
Delmar G. A. Cabral, Brandon Allen, Fabijan PavoÅ¡eviÄ +6
We introduce a multicomponent unitary coupled cluster framework for quantum simulations of molecular systems that incorporate both electronic and nuclear quantum effects beyond the…
Universal initial state preparation for first quantized quantum simulations
Jack S. Baker, Gaurav Saxena, Thi Ha Kyaw
Preparing symmetry-adapted initial states is a principal bottleneck in first-quantized quantum simulation. We present a universal approach that efficiently maps any polynomial-size…
