A document about quantum teleportation is summarized in 3 sentences:
Sender Alice wishes to teleport an unknown quantum state to receiver Bob without sending the original particle. This is done by Alice and Bob initially sharing an entangled pair of particles. Alice performs a joint measurement on the unknown state particle and her entangled particle, sends the results to Bob, who uses it to perform a unitary transformation on his particle and recreate the original state. The protocol allows transfer of quantum information between particles in a non-classical way using entanglement and classical communication.
Teleportation belongs to Quantum Physics, Quantum Teleportation is a process by which quantum information (e.g. the exact state of an atom or photon) can be transmitted (exactly, in principle) from one location to another, with the help of classical communication and previously shared quantum entanglement between the sending and receiving location.

What are the methods of implementing ANN using Quantum computing
Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. Currently used popular public-key encryption and signature schemes can be broken by quantum adversaries. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical communication. For example, it is impossible to copy data encoded in a quantum state and the very act of reading data encoded in a quantum state changes the state. This is used to detect eavesdropping in quantum key distribution.
Multi Qubit Transmission in Quantum Channels Using Fibre Optics Synchronously...researchinventy
A quantum channel can be used to transmit classical information as well as to deliver quantum data from one location to another . Classical information theory is a subset of Quantum information theory which is fundamentally richer, because quantum mechanics includes so many more elementary classes of static and dynamic resources. Quantum information theory contains many more facts other than described here, including the study of quantum data processing, manipulation and Quantum data compression. Here we consider quantum channel as Bosonic channels, which are a quantum-mechanical model for free space or fibre optic communication. In this paper the overview of theoretical scenario of quantum networks in particular to multiple user access to the quantum communication channel is considered. Multiple qubits are generated in different system, the proper alignment of qubits is a must it can be first come first serve or round robin fashion. The received data are grouped into codewords each of n qubits and quantum error correction is performed. These codewords are agreed between the transmitter and the receiver before transmitting over the quantum channel known as valid codewords.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

An unknown quantum state ]P) can be disassembled into, then later reconstructed from, purely
classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) correlations. To do
so the sender, "Alice," and the receiver, "Bob," must prearrange the sharing of an EPR-correlated
pair of particles. Alice makes a joint measurement on her EPR particle and the unknown quantum
system, and sends Bob the classical result of this measurement. Knowing this, Bob can convert the
state of his EPR particle into an exact replica of the unknown state ]P) which Alice destroyed.

The existence of long range correlations between
Einstein-Podolsky-Rosen (EPR) [1] pairs of particles
raises the question of their use for information transfer.
Einstein himself used the word "telepathically" in this
contempt [2]. It is known that instantaneous information
transfer is definitely impossible [3]. Here, we show that
EPR correlations can nevertheless assist in the "telepor-
tation" of an intact quantum state from one place to
another, by a sender who knows neither the state to be
teleported nor the location of the intended receiver.
Suppose one observer, whom we shall call "Alice, " has
been given a quantum system such as a photon or spin-&
particle, prepared in a state ]P) unknown to her, and she
wishes to communicate to another observer, "Bob," suf-
ficient information about the quantum system for him to
make an accurate copy of it. Knowing the state vector
a perfectly accurate copy.
A trivial way for Alice to provide Bob with all the in-
formation in [P) would be to send the particle itself. If she
wants to avoid transferring the original particle, she can
make it.interact unitarily with another system, or "an-
cilla, " initially in a known state ~ap), in such a way that
after the interaction the original particle is left in a stan-
dard state ~Pp) and the ancilla is in an unknown state
]a) containing complete information about ~P). If Al-
ice now sends Bob the ancilla (perhaps technically easier
than sending the original particle), Bob can reverse her
actions to prepare a replica of her original state ~P). This
"spin-exchange measurement" [4] illustrates an essential
feature of quantum information: it can be swapped from
one system to another, but it cannot be duplicated or
"cloned" [5]. In this regard it is quite unlike classical
