Quantum entanglement

Quantum Entanglement Quantum entanglement, also known as “spooky action at a distance” as first referred to by Einstein, is a phenomenon which occurs when two or more particles interact in such a way that their physical states can be described as one whole system rather than as each particle separately. The particles spin in opposite directions to each other and, no matter how far away each particle is from the other, if one particle changes its spin the other particle/s will instantaneously change

Entanglement is one of the most fundamental and yet unintuitive concepts in quantum mechanics. Maximally entangled two-qubit states, often called Bell states, where shown to violate classical (local) correlation properties [33, 34] and are an essential building block for quantum communication and distributed quantum computation. Unfortunately, such entangled states are also difficult to generate and sustain as interaction with a noisy environment typically leads to rapid loss of their unique quantum

physicist working on quantum mechanical aspects of condensed matter and solid state physics. My past research highlights coherence, entanglement, and topology in condensed matter systems. These features are unique in quantum systems, and can give rise to phenomena that do not have classical counterparts. Target systems of my interest include mesoscopic/nanoscopic systems such as graphene, spintronics, topological insulators, and strongly correlated electron systems such as quantum magnetism, unconventional

Quantum Computing and Its Relation to Computer Science I have decided to write my paper on Quantum Computing. This is a difficult subject for me to wrap my head around, however I feel it is a very important field to look into more closely. Quantum Computing relates to the studies I have chosen, in the fact that it is actually a field that could potentially change Computer Science as it is known today. This could affect me in unforeseen ways, and I feel I need to know about it in order to

In 1964, John Bell set out to test the arguments originally described in the EPR paper and later more eloquently describe by David Bohm. In the paper by Bohm, he shows how one could conceive of an experiment to mirror the conceptual situation put forth in the EPR paper, by examining the dissociation of a diatomic molecule whose total spin angular momentum is zero. For example, the hydrogen molecule into two hydrogen atoms. In the experiment, the hydrogen atoms would separate after interaction, in

Quantum Computing Less than 100 years ago, beginnings of the “new quantum theory” began. Only about 55 years after the new quantum theory began to emerge the idea that quantum phenomena can be used to perform computations. The idea being for a quantum computer was that classical computers would take an extremely long time to perform huge calculations, when a simple quantum system perform these same calculations all the time. One property that quantum computers have been observed to have was the

“Experience is not what happens to you; it is what you do with what happens to you”. That is what my dad was saying in the big screen in front of me, quoting Aldous Huxley, next to my mom, both smiling widely and a bit dewy-eyed. It was a video they recorded unbeknownst to me that was being shown at the Jenkins Foundation scholarship awards ceremony; a night that will last in my memory for the rest of my life. An acknowledgment that came almost as unexpected as the realization that I would study

Quantum Cryptography is the newest technology in the field of Encryption and proved to be most secure as of now. In this paper we will discuss what quantum cryptography is and what makes it most secure and unbreakable. Introduction All our classical computer cryptography methods are basically based on some mathematical calculations which are quiet easy to implement in one direction but very difficult to process in the other direction. As RSA(Rivest-Shamir-Adleman) algorithm which is one of the

of auxiliary assumptions to consider. The primary hypothesis and all of these auxiliary hypotheses are effectively being tested together. In this case, the Alain Aspect experiment was testing entanglement between co-generated and entangled particles. Their behavior was compared to results predicted by Quantum Mechanics and results predicted by Bell’s Inequality. The experiment

Sawyer, we are transported into a parallel universe. In this unpolluted world that is populated by Neanderthals, there is a sophisticated computing system, we know as a quantum computer. As of 2014, quantum computers are still in their infancy, and have been prophesied since the early 1990s. However, work on building a quantum computer, and creating algorithms compatible with one, began around the turn of the century. As one of only seven sci-fi writers in the world, and the only Canadian, who has
