PADQOC, high-performance solver for Quantum Optimal Control

Michael Chen

Designing control pulses to generate desired unitary evolution subjugated to experimental constraints (e.g., decoherence time, bandwidth) is a common task for quantum platforms, these type of problems are often addressed in the context of quantum optimal control. Parallel Automatic Differentiation Quantum Optimal Control (PADQOC) is an open-source, Python based general quantum optimal control solver built on top of Tensorflow 2. It is designed to be fast, extensible and useful for controlling general quantum systems.

Quantum Obvious Transfer using Coherent States

David Reichmuth, Heriot-Watt University

One-out-of-two (1-2) oblivious transfer is a cryptographic primitive, in which a sender holds two bits, x0 and x1, and a receiver receives one of them, in such a way that the receiver does not know both bits, and the sender does not know which bit the receiver obtained. While information-theoretical security for quantum versions of such protocols is not possible, it is of interest to examine possible security bounds, which previous work has shown to be set at 0.749 in “complete” protocols employing pure symmetric states.
