Quantum simulation of scattering amplitudes and interferences in perturbative QCD
Herschel A. Chawdhry, Mathieu Pellen, Simon Williams
A flagship application of quantum computers is the simulation of other quantum systems, including quantum field theories. In this article, we show how quantum computers can be empl…
Quantum algorithms for the simulation of QCD processes in the perturbative regime
Herschel A. Chawdhry, Mathieu Pellen
Theoretical predictions for high-energy collision processes at particle colliders, such as the Large Hadron Collider (LHC), rely on calculations in perturbative Quantum Chromodynam…
Rational-function interpolation from p-adic evaluations in scattering amplitude calculations
Herschel A. Chawdhry
Numerical interpolation techniques are widely employed for calculating large rational functions in scattering amplitude computations. It has been observed in recent years that thes…
Interpolation of rational functions in loop calculations by using p-adic numbers
Herschel A. Chawdhry
The calculation and manipulation of large multi-variable rational functions is a key bottleneck in multi-loop calculations. In these conference proceedings, based on my article [Ch…

Herschel A. Chawdhry
Numerical reconstruction techniques are widely employed in the calculation of multi-loop scattering amplitudes. In recent years, it has been observed that the rational functions in…

Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In these conference proceedings, we discuss quantum algorithms for the simulation of p…
Quantum simulation of colour in perturbative quantum chromodynamics
Herschel A. Chawdhry, Mathieu Pellen
Quantum computers are expected to give major speed-ups for the simulation of quantum systems. In this work, we present quantum gates that simulate the colour part of the interactio…

Federico Buccioni, Fabrizio Caola, Herschel A. Chawdhry +6
We compute mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons in the high invariant mass region. Our computation is fully d…

We compute the NNLO QCD corrections to three-photon production at the LHC. This is the first NNLO QCD calculation for a process. Our calculation is exact, except for the s…
Ambiguities of the principle of maximum conformality procedure for hadron collider processes
Herschel A. Chawdhry, Alexander Mitov
In any calculation in perturbative Quantum Chromodynamics (QCD) a choice needs to be made for the unphysical renormalisation scale, . The Brodsky-Lepage-Mackenzie/Principle of…

Herschel A. Chawdhry, Matthew A. Lim, Alexander Mitov
We solve the integration-by-parts (IBP) identities needed for the computation of any planar two-loop five-point massless amplitude in QCD. We also derive some new results for the m…
