... Before the advent of the formal development of quantum mechanics, a few simple, fundamental problems were worked out exactly. It was the case of the Bohr atomic model for the hydrogen atom. This kind of problem is treated in quantum mechanics and modern physics textbooks prior to the introduction of ...
Bohmian Mechanics
... Every student or teacher or philosopher of science must at some point have wondered: is there really a problem with quantum mechanics, or is it just that the theory is counterintuitive, the mathematics complicated, the world indeterministic or the textbooks badly written? The unambiguous answer give ...

C191 - Lectures 8 and 9 - Measurement in
... To actually perform a measurement, we bring our system into contact with a meter. The meter, since it is just another physical object, is a quantum system whose initial state we shall suppose is blank, which we’ll notate as |?i. When the system and the meter are brought into contact, they interact w ...

Computing prime factors with a Josephson phase qubit quantum
... A quantum processor (QuP) can be used to exploit quantum mechanics to find the prime factors of composite numbers[1]. Compiled versions of Shor’s algorithm have been demonstrated on ensemble quantum systems[2] and photonic systems[3–5], however this has yet to be shown using solid state quantum bits ...

Quantum teleportation
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. Because it depends on classical communication, which can proceed no faster than the speed of light, it cannot be used for faster-than-light transport or communication of classical bits. It also cannot be used to make copies of a system, as this violates the no-cloning theorem. While it has proven possible to teleport one or more qubits of information between two (entangled) atoms, this has not yet been achieved between molecules or anything larger.Although the name is inspired by the teleportation commonly used in fiction, there is no relationship outside the name, because quantum teleportation concerns only the transfer of information. Quantum teleportation is not a form of transportation, but of communication; it provides a way of transporting a qubit from one location to another, without having to move a physical particle along with it.The seminal paper first expounding the idea was published by C. H. Bennett, G. Brassard, C. Crépeau, R. Jozsa, A. Peres and W. K. Wootters in 1993. Since then, quantum teleportation was first realized with single photons and later demonstrated with various material systems such as atoms, ions, electrons and superconducting circuits. The record distance for quantum teleportation is 143 km (89 mi).
