REVOLUTIONIZING METALWORKING WITH QUANTUM SIMULATIONS

The Brief Byte: The Quasim project is developing quantum-based simulations to improve processes in the metalworking industry that may lead to defect-free and ideally dimensioned metal components.

Highlights:

  1. The Quasim project, led by teams from the German Research Center for Artificial Intelligence and Saarland University, is using quantum computing to create advanced simulations for the metalworking industry. These simulations could drastically reduce the manufacturing rejection rate and lengthy machine downtimes.

  2. To do so, the researchers are developing hybrid models that combine traditional simulation methodologies with quantum technology and machine learning. This integration is crucial for making simulations more accurate and practical in real-world manufacturing settings.

RESEARCH

OVERVIEW OF “PRACTICAL APPLICATION OF QUANTUM NEURAL NETWORK TO MATERIALS INFORMATICS”

QNN Representation | DALL-E

The Brief Byte: This study investigates QNNs for predicting the melting points of metal oxides to demonstrate that QNNs can be effectively used for multivariate regression tasks in materials informatics, achieving or surpassing classical neural networks' performance.

Highlights:

  1. QNNs can surpass the performance of classical neural networks in terms of generalization capabilities, especially with small datasets which is characteristic of materials informatics. The inherent unitarity of quantum circuits provides a natural form of regularization not present in classical NNs.

  2. Different encoding methods and entangler arrangements, were tested. Shallow-depth ansatzs paired with sufficiently entangled circuits achieved high expressibility without overfitting.

  3. The QNN models were implemented using Pytket and Qulacs. Mean squared error was used as the cost function, the Powell method was used to optimize learning parameters, and k-fold cross-validation was used to assess model accuracy.

RESEARCH

OVERVIEW OF “GENERATION OF SCALABLE MANY-BODY BELL CORRELATIONS IN SPIN CHAINS WITH SHORT-RANGE TWO-BODY INTERACTIONS”

The Brief Byte: This article discusses the generation of scalable many-body Bell correlations in spin chains with short-range two-body interactions. It highlights that scalable quantum resources like many-body entanglement and Bell correlations can be dynamically generated using a finite range of interactions.

Highlights:

  1. Scalable many-body Bell correlations in spin-1/2 chains can be dynamically generated using a minimal range of 4 two-body interactions regardless of the total number of spins.

  2. It establishes a threshold range and a threshold time for the appearance of scalable quantum correlations, showing that these correlations can be dynamically generated within a finite interaction range, which challenges the previous belief that long-range interactions are necessary.

  3. The quantum states with Bell correlations generated through this method can be certified using quantum simulator platforms, making the findings practical for real-world quantum computing applications.

COURSE RECOMMENDATION

FREE IBM COURSE: QUANTUM COMPUTING IN PRACTICE

Something for you to bookmark — IBM just announced a new (and free) course is coming to YouTube soon. This course aims to bring you out of theory and into the practical use of available quantum computers right now. Prioritize the doing over reading/hearing theory to solidify learning faster.
