- 1 Intro
- 2 We need reliable theory to accurately evaluate S-factors at stellar energies
- 3 We combine nuclear forces derived within chiral effective field theory and ab initio methods
- 4 Structure, scattering and reactions obtained with unified treatment of bound and unbound states
- 5 combine it with experimental data to arrive at an improved evaluation of S..(0)
- 6 The ab initio structure and reactions team
- 7 Quantum computers perform calculations by manipulating quantum states
- 8 A physical realization of a qubit is a transmon
- 9 One can also work with registers of d-level quantum systems or qudits
- 10 Physically, quantum gates are realized by irradiation with resonant microwave pulses (found by optimization)
- 11 Quantum computing offers a natural framework for simulating time-dependent scattering theory
- 12 A challenge is to realize useful quantum simulations in this early vacuum tube era' of quanturn computing
- 13 In the near term, this is a self-inflicted problem! Can build custom gates for the problem of interest
- 14 We can extract the energy spectrum from the signal because we are able to run the simulation a long time
- 15 Custom gates enable major performance improvements for state preparation, broader class of problems
- 16 The APS Topical Group On Few-Body Systems
- 17 With minimal number of custom gates, we demonstrated 99% fidelity, 10-fold increase in quantum simulation time
