Antenna subtraction at NNLO for heavy quark pair production at hadron colliders: the non-diagonal channels

A bstract We present the calculation involving the qq , qq ′ and qg partonic channels contributing to heavy-quark pair production at hadron colliders through next-to-next-to-leading order in QCD using the antenna subtraction formalism. The calculation is performed in full colour...

Entanglement fidelity of the Petz decoder for one-shot entanglement transmission

One-shot entanglement transmission is a quantum information processing task where a quantum state is sent to a second party over a noisy channel. The goal of the task is to approximately recover the original state by applying a decoder to the output of the noisy channel. In this...

Probing picosecond depairing currents in type-II superconductors

Abstract Accessing the intrinsic critical current density in type-II superconductors can provide a means to probe microscopic superconducting properties and increase current limits in high-magnetic-field devices and electrical power systems. However, the critical current density...
