Presentation on quantum computers
Quantum computers have the potential to vastly outperform classical computers for certain problems. They make use of quantum bits (qubits) that can exist in superpositions of states and become entangled with each other. This allows quantum computers to perform calculations on all possible combinations of inputs simultaneously. However, building large-scale quantum computers faces challenges such as maintaining quantum coherence long enough to perform useful computations. Researchers are working to develop quantum algorithms and overcome issues like decoherence. If successful, quantum computers could solve problems in domains like cryptography, simulation, and machine learning that are intractable for classical computers.

Quantum computing harnesses the laws of quantum mechanics to solve complex problems too difficult for classical computers. A qubit, the basic unit of information in a quantum computer, can exist in superpositions of states allowing quantum computers to test an exponential number of solutions simultaneously. This enables quantum algorithms to find solutions to problems like protein folding that would take classical computers thousands of years to solve. While quantum computing promises vast speedups, challenges remain in developing algorithms, maintaining the extremely cold temperatures needed, and scaling to larger numbers of qubits.
quantum computing and Quantum Communications
Quantum computing and quantum communications utilize principles of quantum mechanics such as superposition and entanglement to process and transmit information in novel ways. Current research is exploring how to build reliable quantum computers and networks using technologies like ion traps, quantum dots, and optical methods. While still in early stages, quantum information science shows promise for solving computationally difficult problems in fields such as artificial intelligence, cybersecurity, and drug discovery.

Quantum computing uses quantum mechanics and qubits to perform calculations exponentially faster than classical computers for certain problems. It has the potential to enable powerful artificial intelligence and solve problems that are currently unsolvable. However, quantum computers are very difficult to build and operate due to their sensitivity, temperature requirements, and other challenges. The future of quantum computing is promising, with the market expected to reach $2.2 billion by 2026, but significant technological advances are still needed for quantum computers to become practical for general-purpose use.
Quantum computers
Quantum computers are still theoretical but could perform certain calculations much faster than classical computers. They use quantum bits that can exist in superposition and entanglement, allowing them to represent multiple states simultaneously. Current quantum computers have only manipulated a few qubits, but applications could include factoring large numbers and rapidly searching large databases. Significant challenges remain in developing practical quantum computers that can maintain quantum states long enough to perform useful computations.
Quantum Computers
Quantum computers have the potential to solve certain problems much faster than classical computers by exploiting principles of quantum mechanics, such as superposition and entanglement. However, building large-scale, reliable quantum computers faces challenges related to decoherence and controlling quantum systems. Current research aims to develop quantum algorithms and overcome issues in scaling up quantum hardware to perform more complex computations than today's most powerful supercomputers.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

- 3. WHAT IS QUANTUM COMPUTER The Quantum computer is a device that is built on the basis of the quantum mechanics It is very different from a normal computer because it has the unique features when compared to the classical computer To understand Quantum computer we should have a little knowledge on the Quantum mechanics The Quantum mechanics/physics is the branch of physics in which Newtonian laws does not work any more. It is purely based on the quantum particles, the particles which are very small like electrons or photon. The photon is the particle of light which can be travelled as a particle and also wave here many of the physics laws fail.
- 4. How it is different from classical computer Instead of the bits in classical computer the Quantum computer uses Quantum bits also called as Qu-bits. The classical logical bit is represented by binary logic based on either logical high and logical low. Logical high corresponds to binary '1' and logical low corresponds to binary '0' respectively. This makes the possibility of 0 and 1 is 50% each. The Qubit will be in a superposition of the 0 and 1 this makes qubit can be in any probability of getting 0 to 1. b
- 5. The Origin of Quantum Computer Quantum superposition The idea of the quantum computer begin with a paper by Richard Feynman in 1982 and later the scientists such as Deutsch, Shor and Grover gave contribution in algorithms Today this was biggest achievement and many of the computer scientists are working under a quantum computer The superposition of a particle in quantum mechanics can be explained as the particle can be both in spin up and spin down state at same time
- 6. WHAT ARE QUANTUM CIRCUITS The quantum circuits are similar to the circuits which perform the operations using quantum logic gates We have AND, NOT, OR, NOR, NAND and XOR gates in classical computer where as in quantum computing we have H/HADAMARD, PHASE SHIFT, SWAP, PAULI X, PAULI Y, PAULI Z and etc which can perform similar kind of operations. image source: IBM Q experience
- 7. QUANTUM TURING MACHINE vs CLASSICAL TURING MACHINE The Quantum Turing machine/Universal Quantum computer
- 8. QUANTUM COMPUTER vs CLASSICAL COMPUTER The qubit can be in superposition, this makes the quantum computer to make calculations faster than a classical computer If we consider a maze where a computer and a quantum computer are to run a algorithm The classical computer end up losing each possibility and starting from start Where a quantum computer checks out all possibilities at a time by splitting it self by superpositionQUANTUM COMPUTER vs SUPER COMPUTER The super computer is same as classical computer but runs in fast process
- 9. FUTURE OF QUANTUM WORLD • Quantum neurons • Quantum Intelligence • Quantum Cryptography • Bottlenecks into the Tunnels IBM QUANTUM + ARTIFICIAL INTELLIGENCE • Quantum algorithms for learning • Quantum algorithms for decision making • Quantum searching • Quantum game theory
- 10. DISADVANTAGES OF QUANTUM COMPUTING • The main disadvantage of computing is the technology required to implement a quantum computer is not available at present. The reason for this is the consistent electron is damaged as soon as it is affected by its environment and that electron is very much essential for the functioning of quantum computers. • The research for this problem is still continuing the effort applied to identify a solution for this problem has no positive progress. • It cannot store the data we need to have the classical bits to store information.
- 11. CONCLUSION Many companies such as IBM, GOOGLE, MICROSOFT are investing lots of money in making a quantum computer. These companies have a strong belief that this is future. The weird behaviour in small particles made this possible This is the collaboration of the all sciences and this can make a better future REFERENCES Mingsheng Ying, Elesevier – Quantum computation, quantum theory and AI (2009) D.W.Leung, M.MILLER, Quantum computation - IEEE international conference on evolution computing
