'Chemistry is a quantum mechanical problem, designing drugs is a quantum mechanical problem...if you could solve those quantum mechanical problems, you could really make great strides in our knowledge and useful technology.' -MIT Prof. Peter Shor, the deviser of Shor's Algorithm, on the importance of the development of quantum computing WATCH HERE: https://lnkd.in/dBVQeu5f

𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗕𝗮𝘀𝗶𝗰𝘀 #𝟭 𝗽𝗮𝗿𝘁 𝟭 𝗤𝘂𝗮𝗻𝘁𝘂𝗺 𝗕𝗶𝘁 𝗼𝗿 𝗤𝘂𝗯𝗶𝘁 Quantum bit is the alternative to the classical bit, so what is the difference between them? In physics, while the classical bit represents a transistor, the quantum bit or qubit represents a quantum element, i.e. represents one electron, for example. In order to know more about what is the essential difference between a bit and a qubit, we will consider a qubit as an abstract mathematical concept. I will explain how this is done physically in later posts. 𝗦𝘂𝗽𝗲𝗿𝗽𝗼𝘀𝗶𝘁𝗶𝗼𝗻 A qubit carries the values one and zero like a regular bit, but what distinguishes it is that it can carry both values at the same time. How is this done? As we said previously, it is mathematically using the following linear statement or what we call superposition : |ψ> = α |0> + β |1> Which means that it could be carrying the value 0 with probability |α|² and the value one with probability |β|², as we can note that the probability is the square value of a complex number, and yes α and β are complex numbers. In order to get closer to the idea, let us see the geometric representation of the qubit. https://lnkd.in/e5NPKgVm This sphere is often called the Bloch sphere. The ability of a qubit to be in a superposition state runs counter to our ‘common sense’ understanding of the physical world around us. A classical bit is like a coin: it's either heads or tails.

Gordana Dodig-Crnkovic You will enjoy this as a Physicist who became a Computer Scientist and wrote many papers on info-computationalism related to advancing computer science as we know it. The question raised here is whether we can predict the future by knowing about the current state alone (Is it Markovian or non-Markovian evolution). I enjoyed his other book and referred to his writing in the paper I presented at the Turing Centenary Conference in Manchester (2012). https://lnkd.in/gpyGVyN "The Turing O-Machine and the DIME Network Architecture: Injecting the Architectural Resiliency into Distributed Computing." We have come a long way from there with the General Theory of Information. We have a better understanding of the five C's discussed in is4si conference several years ago by Terrence Deacon.

Quantum mechanics was developed between 1900 and 1925. Despite that, for many years even some of the simplest systems seemed to be beyond the human ability to model with quantum mechanics. In #1980, Paul #Benioff described the first quantum mechanical model of a computer. In the same year, Yuri #Manin motivated the idea of quantum computing in his book Computable and Uncomputable. At the First Conference on the Physics of Computation, held by the Massachusetts Institute of Technology (MIT) in #1981, Paul Benioff and Richard Feynman gave talks on #quantumcomputing. While Benioff showed that a computer can operate under the laws of quantum mechanics, #Feynman proposed a basic model for a quantum computer, arguing that it appeared to be impossible to efficiently simulate an evolution of a quantum system on a classical computer.

Schrödinger's Cat and the Quantum Conundrum: Schrödinger's Cat, a thought experiment by physicist Erwin Schrödinger in 1935, challenges our understanding of reality through a paradox involving a cat, a sealed box, and quantum principles like superposition and entanglement. The cat's fate exists in a superposition of alive and dead states until observed. The act of observation, according to the Copenhagen interpretation, collapses the superposition into a definite outcome. Various interpretations, such as Many-Worlds and Transactional, offer different perspectives on the paradox. Beyond theoretical discussions, quantum mechanics finds practical applications in technologies like quantum computing and cryptography.Schrödinger's Cat serves as a gateway to exploring the mysteries of the subatomic world, pushing the boundaries of our comprehension. #snsinstitutions #designthinking #designthinkers
