Quantum Computers :: quantum physics computer

introduction A quantum computer is one which exploits quantum-mechanical interactions in order to function; this behavior, found in nature, possesses incredible potential to manipulate data in ways unattainable by machines today. The harnessing and organization of this power, however, poses no small difficulty to those who quest after it. Subsequently, the concept of quantum computing, birthed in the early 80's by physicist Richard Feynman, has existed largely in the realm of theory. Miraculous algorithms which potentially would take a billionth of the time required for classical computers to perform certain mathematical feats, and are implementable only on quantum computers, as such have not yet been realized. A two-bit quantum system, recently developed by a coalition of researchers, constitutes the sole concrete manifestation of the idea. The intent of these pages is provide a rudimentary understanding of the roots and progress of quantum computing, in order that one may realize the presence and growing significance of this fusion of quantum theory and computation. overview The bit, most basic unit of information within a computer, is the building block for all data residing within. An alphanumeric character, for example, usually consumes 1 byte, or 8 bits, of memory. A 2-byte, unsigned integer would be allowed to range from 00000000 00000000 to 11111111 1111111 in binary, or 0-65535 in decimal notation (0-216). The â€Å"bit† of a quantum computer, referred to as qubit (short for quantum bit), might be represented as an atom. Qubits, however, possess an intrinsic and most significant quality: they may simultaneously be assigned 0 or 1, the probability of each expressed as a numerical coefficient. This ability allows quantum computers to exist in multiple states at once, called superposition by those knowledgeable of such things. Subsequently, actions may be carried out in all states simultaneously, allowing parallel operations to be performed with one processing unit. A phenomenon dubbed â€Å"entanglement† joins qubits together in a quantum system. Superpositioning opens the way for several fascinating and potentially problematic uses for quantum computers. Factoring numbers of several hundred digits, a tactic needed to crack some encryption schemes currently in use, would take billions of years on the fastest supercomputers. Theoretically, this might take a year on quantum computers.

Alternatives to Prison Summary

need of â€Å"correction† than the prisoner. The caring communities have yet to be built. from Instead of Prisons: A Handbook for Abolitionists Why Decriminalize? Abolitionists advocate drastically limiting the role of criminal law. We do this not because we wish to encourage certain behaviour, but because we realize that criminal sanctions are not an effective way of dealing with social problems. There are far too many laws on the books. It would be prohibitively expensive to enforce them all. This results in unjust and arbitrary law enforcement. Powerless persons are imprisoned while more powerful persons go free. People of colour, first nations and poor people bear the brunt of unequal law enforcement. The crimes most frequently considered for decriminalization are those which are â€Å"victimless†Ã¢â‚¬ ¦. offenses that do not result in anyone's feeling that she has been injured so as to impel himher to bring the offense to the attention of the authorities †¦. behaviour not injurious to others but made criminal by statutes based on moral standards which disapprove of certain forms of behaviour while ignoring others that are comparable. A system â€Å"bursting at its seams† is perhaps the most visible effect of overcriminalization. Overcriminalization encourages the wide use of discretionary power in law enforcement. Because there is no complainant, police resort to questionable means of enforcement. Investigative techniques used to gather evidence are often immoral and sometimes illegal. These include entrapment, use of informers, wiretapping and use of constitutional rights such as illegal search and seizure, invasion of the right to privacy and self-incrimination. from Instead of Prisons Alternatives to Incarceration Imprisonment should be a last resort. The presumption should be against its use. Before any offender is incarcerated, the prosecution should bear the burden of proving in an evidentiary hearing that no other alternative exists. An equal burden should be required for the denial or revocation of â€Å"good time†, probation and parole, which really are only other ways of imposing imprisonment†¦ We should further reduce our excessive reliance on prisons by making extensive use of alternatives to imprisonment, such as fines, restitution, and other probationary methods, which could at least as effectively meet society's need for legal sanctions. However, such alternatives must be made available to all people who have committed similar offenses, so as not to become a means for the more affluent to buy their way out of prison. And where some kind of confinement seems necessary, halfway houses, community centres, group homes intermittent sentences, and other means of keeping offenders within the community should be preferred to prison. from A Program for Prison Reform

The Individuals With Disabilities Education Act - 1535 Words

THE INDIVIDUALS WITH DISABILITIES EDUCATION ACT (IDEA) IDEA is the main law addressing the education of children and adolescents with disabilities. It ensures all individuals with disabilities between the ages of 3−21 the right to a free, appropriate public education (FAPE), regardless of the nature or severity of the disability. Schools must therefore provide services to meet the particular educational needs arising from a disabling condition that cannot be met in the general educational program. THE NATURE OF SPECIAL EDUCATION Special education is instruction tailored to the unique learning needs of an exceptional student. A host of characteristics may make a student ‘exceptional,’ including sensory, physical, cognitive, or communication abilities that differ from those of same-age peers in a way that is relevant to the student’s education. IDEA specifies 13 disability categories that call for special education if the student requires alternate materials, teaching techniques, equipment, and/or environments to learn as a result of a disability. Special education instruction is more controlled in pace, complexity, persistence, structure, reinforcement, teacher-pupil ratio, content, and progress tracking in comparison to what the student’s peers experience in the general education classroom. Some students will require accommodations, or changes to how they learn, whereas other students will excel from modifications, or changes to what they learn.
