5. Tutorial: Introduction to Quantum Error Correction.

James Wootton

6/20/24, 8:00 AM

We will look at the basics of quantum error correction, starting from the repetition code and then focusing on surface codes. Finally we’ll consider the outlook towards high-rate LDPC codes.

Natalia Ares

6/20/24, 10:00 AM

Machine learning is rapidly proving indispensable in tuning and characterising quantum devices. By facilitating the exploration of high-dimensional and complex parameter spaces, these algorithms not only allow for the identification of optimal operational conditions but also surpass human experts in the characterisation of different operational regimes. I will present the first fully...

Roberto Gargiulo

6/20/24, 2:50 PM

The computation of classical Ising partition functions, coming from statistical physics, is a natural generalization of binary optimization.
This is a notoriously hard problem in general, which makes it an especially interesting task to consider in the search for practical quantum advantage in near term quantum computers.
In this work we view classical Ising models (on certain graphs) as...

Karthikeyan Sabari Ganesan, Vishal Saraswat

6/20/24, 2:50 PM

In digital communication, authentication, integrity, and confidentiality are fundamental security requirements. These properties enable robust security controls such as secure boot, secure update, secure access, and secure TLS across connected devices. However, existing cryptographic algorithms, while effective against classical threats, vulnerable to powerful quantum attacks. In this paper,...

Csaba Czabán, Márton Karácsony, Zoltan Zimboras, Zoltán Koralovszki

6/20/24, 2:50 PM

Photonic quantum computing has recently emerged as a promising candidate for fault-tolerant quantum computing by photonic qubits. These protocols make use of nondeterministic gates, enabling universal quantum computation.
However, the suggested solutions heavily use particle number resolving detectors (PNRDs), which are experimentally hard to realize and are usually biased in practice. We...

Javier González Conde

6/20/24, 3:30 PM

Classical information loading is a crucial task for many quantum algorithms, playing a fundamental role in the field of quantum machine learning. Consequently, the inefficiency of this loading process becomes a significant bottleneck for the application of these algorithms. In this context, we present and compare algorithms for the amplitude classical data into a quantum computer.

Hamid Tebyanian

In this paper, we study two well-characterized continuous variable detections, homodyne and heterodyne, and then compare their performance in phase keying or amplitude modulation schemes where indistinguishable states are being measured. We compare their performance in terms of generation rate and amount of extractable information necessary for quantum secure applications.
