It suggests that parallel worlds can interact on the quantum level, andin fact that they do."T he idea of parallel universes in quantum mechanics has been around since 1957, " explained Howard Wiseman, a physicist at Griffith University in Brisbane, Australia, and one of the physicists to ...

In quantum mechanics, the only perfectly distinguishable states are those that are orthogonal. For qubits, these are states that are perpendicular on the Bloch sphere. It so happens that the Bell states are orthogonal, so when it comes time for Bob to measure the qubits, he can perform an ...
Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents—electrons, protons, neutrons, and other more
The computational efficiency of quantum mechanics can be characterized in terms of the qubit circuit model, which is defined by a few simple properties: each computational gate is a reversible transformation in a connected matrix group; single wires carry quantum bits, i.e. states of a three-dim...
why the behaviour of the atomic world should conform to that of the familiar, large-scale world. It is important to realize that quantum mechanics is a branch ofphysicsand that the business of physics is to describe and account for the way the world—on both the large and the small scale...
2After visiting the musée, I learned that my classical-mechanics professor had been referring to the Foucault pendulum that hangs in the Panthéon, rather than to the pendulum in the musée. The musée still contains the pendulum used by Foucault in 1851, whereas the Panthéon has only a copy...
perform calculations on a quantum computer, it is necessary to interact several qubits, and in such a way that they form a single quantum system. Then this system should be allowed to develop according to the laws of quantum mechanics and after a certain time find out what state it has ...
In this work we introduced an operational formalism to apply quantum mechanics from the point of view of a reference frame attached to a quantum particle, which we call quantum reference frame. This reference frame has its own degrees of freedom, which can be in quantum superposition or entangle...
Measurement lies at the heart of quantum mechanics and allows one to probe a quantum system of interest through a measuring pointer (an apparatus) coupled to the system’s observables. The interaction between the system and pointer is later classically amplified for the outcome to be seen macrosc...
