    Cryptography has come a long way since invisible ink and decoder rings. Today we rely on the magic of prime numbers to keep our online transactions and records secure. I'll describe cryptosystems work, from Caesar to the Kama Sutra to modern e-commerce, and how a future quantum computer would break them. I'll then describe what kinds of cryptography might remain secure even after quantum computers are built. Nothing beyond high school math, I promise!

      Recent research shows real time tracking of a quantum system is possible. One of the most famous examples of the strangeness of quantum mechanics is the paradox of Schrödinger's cat, A cat in a box whose fate is decided by subatomic particles, is both dead and alive until observed known as the Copenhagen Interpretation. Similar to when a quantum particle interacts with the outside world, it loses its quantum behavior and collapses into a classical state. This paper shows it is possible to follow the quantum particle before it collapses into a classical state. It is found that quantum particles follow the classical path of least resistance, allowing scientists to steer quantum behavior in a certain direction.

        Awareness of quantum physics has entered the mainstream culture by now, and it’s ideas are part of daily expression, but do we know what is actually meant by “quantum computing”? Jonathan Home of the Institute of Quantum Electronics, at ETH Zurich, answers some questions about what we can expect from this “new structure for logic.” Created by Featurezoo (http://featurezoo.net) for ETH Zurich.

        • Quantum Computing versus traditional computing

          The Hilbert space is yet the base for all practical technological applications. How can it be possible that a useful fiction, a mathematical-only artifice could carry us such an amount of Wall Street-quoted technological and industrial applications ? As an example, no one doubts about the reality of the switchings of the CPUs and of the logic gates in the Programmable Logic Controllers (PLCs) which let worldwide Food and Beverage Bottling Lines run in this moment. No one doubts that what those CPUs and I/Os are performing, are computations over a programmed algorithm. A second attempt to pass around the uncomfortable implications of the reality of the Quantum Field, tried to limit to the atomic and subatomic scales the domain of application of noncommutative geometry rules. But, other examples of noncommutativity were yet known also for objects of the spacetime macroscale of dimensions we directly perceive without any instrumental aid. As an example the geometric rotations of a solid, a massive 3-dimensional book. Then, non commutativity represents rules of general application. The key point is that Hilbert space represent a system before the measurement action when all of the states of the system exist in superposition. The act to measure a status for a variable (or, Trigger, e.g. the time of passage of a container front of a photoelectric sensor) reduces the observed value to a single point, ...what does not mean that the others do not exist any more or they did not existed at all before the measurement. Additional confirmations that Quantum Mechanics had since the start the multiversal scenario deeply embedded into its logic. The tree-like branching logic which explains why and how our industrial world exists and operates. One of the applications of the quantum computers is the Binary Classification. Electronic Inspectors in the Food and Beverage Bottling Lines are Binary Classifiers. (In another page of this site we’ll explain why the ideal Bottling Control is a device calculating in binary way as usual but, in the Hilbert space). From Decoherence we learnt that the general mechanisms and phenomenons arising from the interaction of a macroscopic quantum system with its Environment, strictly depend on the strength of the coupling between the considered degree of freedom and the rest of the world. The first commercial application of the Quantum Computing, also devoted to the Binary Classification main task of all Electronic Inspectors, is the D-Wave's “Vesuvius” Central Processing Units are a system of 512 quantum bits (qbits). - 512 superpositions of the Ψ wave functions, preserved longer than possible in the Hilbert space; - operating at temperatures of 0.02 K (-272.98 ºC), extremely close to the absolute zero; - protected by induction of external electromagnetic fields by fifteen levels of Faraday cages. A mind-boggling amount of other branches of the Multiverse where the computer exists, each one processing the same original qbit with differences from one to another in the variable processed, reduced to 1 bit. Moreover they: - adopt Rainier processors and Josephson-effect junctions, rather than Silicium-based processors. Josephson junctions are the most basic mesoscopic superconducting quantum device; - handle qubits which can slowly be tuned (annealed) from their superposition state (say where they are 0 and 1 at the same time) into a classical state where they are either 0 or 1. When this is done in the presence of the programmed memory elements on the processor, the 0 and 1 states that the qubits end up settling into gives the answer to an user-defined problem.

            The Department of Physics and the George Gamow Memorial Lecture Committee proudly presents the Forty-Ninth George Gamow Memorial Lecture, "Quantum Computers and Schrödinger's Cat" by Nobel Laureate, NIST Fellow and Professor Adjoint, Dr. David Wineland. The lecture was on Tuesday, April 1st beginning at 7:30 P.M. in Macky Auditorium on the CU Boulder campus. Abstract: As the size of computer logic gates and memory elements approaches the atomic scale, we are forced to deal with the constraints imposed by the laws of quantum mechanics. However, we now also know that a computer based on quantum mechanics could solve certain problems that are intractable on conventional computers. Interestingly, if this device could be made on a large scale it would have the same characteristics as Erwin Schrödinger’s famous 1935 hypothetical cat that could be both dead and alive at the same time. In part, I will discuss how a quantum computer might be realized with a collection of atomic ions. For more information about the lecture series, go to: http://physics.colorado.edu/Gamow
