Simulating quantum collision models with Hamiltonian simulations using early fault-tolerant quantum computers

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Kushagra Garg, Zeeshan Ahmed, Subhadip Mitra, Shantanav Chakraborty, | Summary: We develop randomized quantum algorithms to simulate quantum collision models, also known as repeated interaction schemes, which provide a rich framework to model various open-system dynamics. The underlying technique involves composing time evolutions of the total (system, […]

Tracing the imprints of large-scale magnetized structure on $γ$ rays from GRB 221009A

Kavli Affiliate: Nicola Omodei | First 5 Authors: Saikat Das, Soebur Razzaque, Nestor Mirabal, Nicola Omodei, Kohta Murase | Summary: We search for possible GeV-TeV gamma-ray imprints of ultrahigh-energy (UHE; $gtrsim 0.1$ EeV) cosmic ray (CR) acceleration in the large-scale structures surrounding the brightest gamma-ray burst (GRB) explosion, GRB 221009A. Using 1.25 years of post-event […]

Cosmological Evolution of Fast Radio Bursts and The Star Formation Rate

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Sujay Champati, Vahé Petrosian, , , | Summary: We investigate the cosmological evolution of the luminosity and redshift of FRBs. As is the case for all extragalactic sources, we are dealing with data that are truncated by observational selection effects, the most important being the flux limit, […]
