Bootstrapping High-Energy Observables
Faizan Bhat, Debapriyo Chowdhury, Aninda Sinha +2
In this paper, we set up the numerical S-matrix bootstrap by using the crossing symmetric dispersion relation (CSDR) to write down Roy equations for the partial waves. As a motivat…
Complexity for one-dimensional discrete time quantum walk circuits
Aranya Bhattacharya, Himanshu Sahu, Ahmadullah Zahed +1
We compute the complexity for the mixed state density operator derived from a one-dimensional discrete-time quantum walk (DTQW). The complexity is computed using a two-qubit quantu…
A Celestial Route to AdS Bulk Locality
Faizan Bhat, Ahmadullah Zahed
We prove a precise form of AdS bulk locality by deriving analytical two-sided bounds on bulk Wilson coefficients. Our bounds are on the Wilson coefficients themselves, rather than…
A simple coin for a entangled walk
Ahmadullah Zahed, Kallol Sen
We analyze the effect of a simple coin operator, built out of Bell pairs, in a Discrete Quantum Random Walk (DQRW) problem. The specific form of the coin enables us to find an…
